The vulture is three-stranded. Sip cable - what is it?

⁰

The old, uninsulated, renewed lines of life by electricians step by step enter the past. In the present hour, on the redundant lines, more and more often, insulated darts are stuck. SIP is deciphered as "self-supporting insulated darts". The stinks serve for the life of new power lines, as well as for the replacement beaten darts yakі do not wash the insulation.

vidi

The SIP cable is subdivided on the main type in the fallage in the material and design features. Kozhen okremy viglyad the cable is considered with a diameter and a number of cores, obviously zero explorer, insulation material. The main power of such cables is the presence of insulation. Vіdpovіdno to GOST stench vvazhayutsya wires, but for the fact tse cables.

SIP-1 cable

This type of cable is made up of aluminum conductors, insulated with PET material. To briefly describe the type of insulation, we can say that PET is polyethylene terephthalate, a thermoplastic polyester material that looks like synthetic fabric or slinky. The cover does not let through the ultraviolet light. Nulyova lived in 2 ways: insulated and without insulation. СІП-1А - cable is isolated with zero. On the target, indicate the letter "A".

SIP-2

This type of cable may have a similar design. Vіdmіnіst polyaє seldom have material_іlіїlyatsії. We all lived insulated with special polyethylene insulation (PET). This type of cable is twisted when a power transmission line is installed with a voltage of up to 1000 V. It is installed for stretching the head lines and auxiliary wires. Such a cable is dotsilno vikoristovuvat for pivnіchnyh regions and areas with a peaceful climate. Vin can also be used for summer cottages for washing the voltage of 380 V.

Behind the standard, the droti is guilty of vitrimuvat trivale heating to the right temperature. SIP-1A can be 70 degrees, and SIP-2A building is 90 degrees. When installing the cable, it is necessary to tie the cable to the smallest radius of the wig, which, according to the rules, is responsible for the cable that is larger than the 10-fold diameter of the cable.

SIP-3

This version of the cable may be significant. This design is made up of a steel core with aluminum braiding, as it is made up of an alloy of aluminum, magnesium and silicon. Calls are used for insulation with PET, as they do not pass ultraviolet light. Such a 1-core wire wins for everyday life electric lines 20 kilovolts. Vіn recommendations for zastosuvannya in different types climate, arctic and sharp continental climate. For the standard, the temperature is normal and can be 70 degrees, the temperature is allowed -20 + 90 degrees.

SIP-4

The cable is made from a number of pairs of wires. Zero drіt vіdsutnіy. For example, the designation is the marking "H", as it is known about those that the alloy lived as a material. As letters are not known, it means that the core was crushed from pure aluminum. Zovni lived є іzolyatsіya z thermoplastic PVC, which can stіykіst to ultraviolet.

SIP-5

The attachment of the brand drot is similar to the SIP-4 cable, but it is also covered with insulation material, like a vikonan with PET. Tse allows you to increase the trivality of the allowable temperature by 30%. The SIP-5 cable is used for a 2.5 kV transmission line link, as well as for bringing to work, street lighting, and lighting at the gatehouses. The application of SIP-5 is recommended for regions with a peaceful and cold climate.

The technical power of the SIP of different types is indicated in the tables.

Markuvannya

The CIP cable is designated for additional numbers, letters and insulation. Let's look at the butt of the identification of the SIP-1 dart, decipher yoga:

SIP - 1 - 3 × 70 + 1 × 95 - 0.6 / TU 16-705.500 - 2006

The cable may have 3 phases with a span of 70 mm2, one core without insulation, with a span of 95 mm2. operating voltage alive 0.6-1 kilovolt.

Marking the cable follows the rules of singing, in this order:

Lives of phases are designated by numbers, swags, by the way of ruku chi embossing.
Null's vein does not show up.
The replacement of numerals and letters can be filled with a color scheme with a width of over 1 mm.
Additional living lighting is designated B1, B2, B3.
The cable is marked through the skin 50 cm in all cases.
The designation of standard sizes: the width of the sign is over 2 mm, the height is 5 mm.
Additional controls may have lived longer.
Marking can be resistant to ultraviolet changes and be protected by a long term of service.

Having deciphered the cable designation for yoga marking, you can look at yoga and choose the right one.

power cable

The technical data of the cable may be standardized according to GOST R 52373 - 2005. This standard specifies the installation of a CIP cable for power lines no higher than 35 kilovolts. Peretin lived up to 240 mm2. On the plots of the main line of the power transmission line, the diameter of the main cable should be wider than the cut of the core of the main cable. The technical characteristics of the cable allow it to be installed for the organization of street lighting. For such tasks, a cable made of 25 mm 2 cores is used.

The standard has a characteristic of boundary values. Even if the parameters do not match with GOST, such a test cannot be performed.

Let's take a look at the main parameters of the drone for the standard:

The most admissible vanity. Chim more stretch, the more admissible vanity is higher.
The maximum operating temperature
Between temperatures in critical mode (130 degrees).
Permissible radius of the wig (no less than 10 core diameters).
Warranty term - 3 years.
The term of service for the mind of the vikonnanny could be exploited for over 40 years.

Deyakі danі cable can v_znyatisya at different virobnіv, however, the stench is to blame buti in the range of standard values.

SIP cable fittings

The cable kit includes mounting elements and fittings:

Prokolyuyuchi zatiskachi, yakі podnuyutsya s be-what kind of cable. The stench is to give the vikonati a hermetically sealed seal, to the one who does not know how to live in case of isolation. After the installation of fasteners on the insulation, the tightening of the fastening bolts is vibrated. The teeth pierce the insulation and make contact with the metal core.
Vіdgaluzhuvalna fittings vikoristovuєtsya for pіdtrimki and tightness lived. Zatyskachi vikonanі for the principle that will simplify the installation and dismantling of the dart without additional possession. The tensioner is fixed for hanging the cable to the surface.
Anchor fastening to serve for fastening the fasteners. With hooks and zastosovuetsya bandage stitch. Fixing fittings can withstand up to fluctuations in temperature.

Installation specifics

SIP cable to serve as a line on the open air. Yogo connection is connected to the central line. In order to connect such a cable to the central line, it is necessary to use the work with the relevant organizations, such as to lie in the middle. Before this, the project is being developed. To install the cable, you need to install special accessories and tools.

For cutting the dart, there are vicorous battens that are pierced, that allow the connection to be made without stripping the cable insulation. Let's connect tips. To move the darts on a length greater than 25 meters, pull the cable between the stomps. Trimachs are fixed on the stovpah for manual and secure installation of the cable.

For carrying out the cable along the facade, special anchors will be installed, which will be connected to the standard cable set. The number of anchors and fasteners may be confirmed by the number of entry veins. It is allowed to run a cable at the alarm no more than 1 m lower. The peculiarity of installing the cable in isolation is the factor that the work can be carried out without vibrating the wire.

If the material of the life of the booth is non-combustible, then CIP is carried out according to old wall conduct a speech. Obviously, it doesn’t give a booth of aesthetics, since the black-colored cable is well seen on the wall, especially on the facade. Sob whom to hide, install on the wall plastic box, but special corrugated pipe. Tim is bigger, like wooden houses.

Sphere zastosuvannya cable 2×16, 4×16

Such marks of drota vikoristovuyut for povtryanyh vіdgaluzhen to budinkov, as well as for laying on the walls of budіvel that sporud.

Cable СІП 2 x 16 is installed for control of internal transmission lines in the premises. Yak vydgaluzhuvalny droti, SIP 2 × 16 is suitable for connecting to the electrics of country cottages.

Although CIP has a lot of insulation, but it is not large, which creates security for installation. The table, for example, for the double-wire SIP-4, helps to select the cable for the brand of the cable:

Zastosuvannya SIP replacement of wires without insulation allows you to prevent short flicker and strum strike when the lines are broken.

Advantages of SIP wires

There is no need to install hard insulators on the line.
The isolated line is safe for fakhіvtsіv, yakі її to serve.
The width of the highway line was changed to the fact that everyone lived together in the same isolation.
Zastosovuєtsya at whatever mind you wait.
Not weak to corrosion.
The handguard of the darts is twisted, and it is easy to see.
Environmentally friendly for people and creatures.
Resistant to overheating of wires.
Simple that easy laying line.

Nedoliki SIP

Three shortcomings include the following factors:

Significant vaga one meter cable. Supports need to be placed more often, lower when standing on a bare dart. The installation of wooden stovpіv does not cause any particular difficulties, the concrete constructions may be high versatility and foldable installation.
With varying degrees of industry, the cable will require reinforced insulation.

Construction repeated lines electric transmissions from the moment of їх vinhoda recognized few changes. The base has lost its weight: the darts are attached to the insulators. The material for the darts is aluminum, which can be low support have a low varity. For greater flexibility, the wires for LEP are prepared with rich iron, and for the increase in strength, steel drill is added to the middle.

The material for the preparation of insulators is porcelain. Sob they didn’t trim the water and drank, cover the surface of the insulators with glaze and ribbed.

The design of the LEP is simple, ensured its wide zastosuvannya, but didn’t include nedolіki, sleddkami such electricians have to fight and dosi.

The form of that covering of insulators does not include their tests.
The bird that sat on the dart for repair, becomes the cause short hum.
Spend all the same vytyagyuyutsya, scho when strong wind produce up to їх rozgoduvannya, shlostuvannya and short zamikannya.
The tree that fell on the line should be brought to a short zamikannya, and sometimes - with a shaved wire.
Z'ednannya lines, which come in, are twisted from the main line. In the meantime, her contact is weak, she warms up and disappears.
To repair the line or connect to it, subscribers will need to be unscrubbed. Otherwise, electricians on high check for deadly inaccuracies.

Podbag tsikh nedolіkіv є road maintenance lines. It is accumulated out of necessity:

postiyny cherguvannya of operational-viznih brigades (OVB);
presence of a warehouse stock of spare parts (insulators, darts);
security of the ESA with transport for arrival before the accident, with assistance for getting to the top (including cars with veils).

Dodamo to the point, whether it be put on a support for the repair of the line - tse robot, tied with a rizik for life and health. I won't demand a high qualification of an electrician, as if they were rocking the rocks. And after hurricanes, bright snowfalls, and after the storms of power transmission lines, they are massive. Energy supply companies recognize the congestion in connection with the supply of electricity to the victims, as well as the support of material supplies for the repair of power transmission lines.

SIP - a new word for the construction of LEP

Thesis, implemented in the design of a self-supporting insulated dart: don't go crazy and isolate yourself. And in the right direction to cover the conductors of the SIP, the vimogi hang out, which inspect their types of conductors of the power cable:

mechanical strength;
durability up to atmospheric fallout, kolivan temperatures;
resistance to ultraviolet;
gnuchkist.

The power rating is suitable for thermoplastic or cross-linked light-stabilized polyethylene. From them, the insulation of SIP wires is prepared.

thermoplastic naming polymers, the building of bagatorase rozm'yakshuvatisya at elevated temperatures and turn around at the exit camp at її zvorotny decrease. Sewing polyethylene prepared for special technology. When the vise of yoga is lifted, the molecules swell with additional bonds between each other, nibbling together. Tse take care of the removed material as an additional mechanical power, and electrical. From the new one they prepare not only SIP dart, but also cables: both low-voltage and high-voltage.

Ale, I would like a polymer that is not built on its own and vitrimat tyagars laid at a new conductor. In SIP, this function is implemented in one of the following ways:

one of the strum-leading cores: PEN or PE, whichever is assigned for safety refrigeration. Її shave chi poshkodzhennya not lead to the defeat of otochuyuchy strums;
zusillya tightness is evenly distributed between us with SIP veins.

Technical characteristics of SIP wires

The fallow type of construction of the SIP dart is subdivided into:

Type	Bearing vein	Insulation material	operating voltage
SIP-1	Chi is not isolated	Thermoplastic polyethylene	Up to 1000 V
SIP-1A	Isolated	Thermoplastic polyethylene	Up to 1000 V
SIP-2 (SIP-2A)	Isolated	Sewing polyethylene	Up to 1000 V
SIP-3	Isolated	Sewing polyethylene	Higher 1000 V
SIP-4	Mustache lived to carry	Sewing polyethylene	Up to 1000 V

Provid brand SIP-1 is not allowed for laying in places accessible to people. On an uninsulated PEN (PE) core, in case of accidents in electrical circuits, it is theoretically possible to have a life-threatening potential. That is why yoga is not laid with facades of houses.

Sewing polyethylene building to work at high temperatures dovkilla. Vin allow heating up to +90˚С, but thermoplastic polyethylene I can work the temperature no more than 70˚С. These parameters include the installation of SIP-1 and SIP-1A.

Provid SIP-3 vikoristovuetsya for the installation of power transmission lines with a voltage of 6 kV and more.

Zastosuvannya dart SIP-4 is less likely to be lined with inputs at budivly. Porіvnjano s SІP-1 and SIP-2 wines may lessen the price for opening. Tsі brands zastosovuyutsya for the installation of main lines of power transmission.

Crimean data about the construction of the construction in the March wire SIP is available for information about the yogo cut and the number of lived. One vein at the warehouse may be less than SIP-3, reshta - from two to five. Peretin varies from 16 to 120 mm2. In vipadkah, if the vein of the SIP is not able to increase the cuts, the vin is indicated okremo. An example of such marking is indicated in the table

Permissible trival strums for SIP wires lie not only in their peretina, but also in the insulation material.

Accessories for the installation of a self-supporting insulated rod

For fixing a self-supporting insulated rod, as well as for installation is not insulated darts, vikoristovuyutsya themselves support. For those who do not need special traverses with pins, insulators are attached to them. Technology of strengthening СІПу інша.

Replace the traverse during installation brackets, which are installed on supports behind an additional mounting line. All smuga from stainless steel, which is sold in rolls. For її tightening that trimming, a tool is installed under the name " strichkonatyaguvach". Through the presence of a new similar handle, the fitters call yoga a “meat grinder”. For skin fastening, a lock is needed. mounting fastening, before which the end of the line should be refueled.

To bring the SIP to the wall of the booth, there are brackets that are fixed on the facade behind the help of hard screws with hex heads.

Conduct to the brackets on the cob and in the end of the line, as well as on the turns, fasten anchor clamps. The stench of the construction, which hobbles and tightly tightens the carrying core of the SIP. Before the anchor, the bracket is free to fasten for help.

Anchor zatyskach for SIP-4 hoist all darts, for dermal z them the anchor may be personalized. The nut is tightened, which tightens the clamp, fixes all conductors at once. Zatyskachi for SIP-4 are issued for two-wire and chotyri-wire lines.

Anchors zatiskachi vykonuyut function natyaguvachіv pіd hour installation. On the reshti supports, the tension is not needed, for that there they win promizhnі zatiskachi, scho win the role of pіdvіsіv Since SIP-4 is not vikoristovuєtsya on the main lines, then the intermediary zatiskachi, zdatnі obtysnut all lived, what they carry, they don’t transfer for the new one.

Electrical installations SIP

Kіntsі СІПу do not deprive of vodkriti, їх іхіуюyуyut for help kovpachkiv: elastomeric or heat-shrinkable.

For the organization of vіdgaluzhen vіd magistralі vikoristovuyutsya vіdgaluzhuvalnі zatiskаі. For skin treatment, one of the phases is treated with a personal touch. The wine is made up of two parts: the conductor of the line is put into one, and the conductor that comes to it is put into the other. Opening for the conductor of the line of the cross, the zatskach is superimposed on the need for a vein, be it necessary. The last segment of the seal of appointments for inserting the conductor only from one side, from the other side ends with a deaf kut, insulating the butt of the dart from the middle of the middle.

After installation, the seal in the space required and the introduction into the new SIP conductor in the galvanic line will be tightened. At the process of tightening the teeth, the seal is pierced through the insulation and pierced into the streamer lived. It is necessary to tighten the control over the chest self-tapping nut, and also stop at good couplings for power cables. A little necessary susilla will be reached, the nut will be broken. It is necessary to reduce to a minimum the impact of the human factor on the efficiency of the task and to rob the robot manually: it is not necessary to climb on the floor with a torque wrench. The next step is to pick up the z'ednannya to be carried out for the help of an additional nut, and the tack is not re-tacked.

After tightening the opening of the nut, it is closed with a cold cap.

For connecting lamps up to the line of vykoristovuєtsya іnshiy grade vіdgaluzhuvalnyh zatiskіv. The socket for connection to the cable should not be dented, which is intended for piercing the insulation of a self-supporting insulated conductor, but the flats that squeeze the cable to the cable of the lamp. In a different principle, the robotic grip is the same.

Є zatiskachi, for the help of those SIP wires are connected to the permanent non-insulated line. To the aluminum dart of the LEP, there is a partial seal, which may look like a clamp, and the SIP is punctured by itself. This view of the day is victorious, as it is connected to a new line, vikonana SIP, or before it comes to the court for the arrival of a spozhivach.

For the introduction of livelihood to the booth, there are two options. First broadcast installation on the street of the shield, in which to enter the SIP Shield, either on the wall of the booth, or on the intermediate support. Vіd nygo to budinku go underground chi povіtryana cable line.

In another mood entrance shield with a knot of shape is installed in the middle of the booth. With this CIP, it is inserted through the metal pipe in the middle and goes straight into the shield. When laying the walls, the SIP will be fixed on them with wall brackets.

Advantages of self-supporting insulated drotu

Suspension of self-supporting insulated wires increase the reliability of electricity supply. Tsej provіd more importantly cut off, vіn navіt vitrimuє falling trees. Short flickers are turned on when wires are lashed, and contact contacts do not require revision.

Move and be safe: when dotik to the dart, it is not possible to hit with a strum. All connections and connections on SIP conductors can be connected under tension, without stopping the insulated tool. Tie on the nuts of the galuzhuvalnyh zatiskachiv іizolovanі vіd provіdnіvіv, until such vykonuєtsya podklyuchennya.

Installation of main, ventilated lines and line of outdoor lighting has become easier. As a result, an hour of installation work was shortened: the line from the SIP can be laid more quickly, the lower LEP with aluminum wires and insulators. It became possible to lay more lines behind these very supports. The stench can’t just walk alone under one, but it’s better to cross at a pretty straight line that be-like a kilkost. Golovnya - so that the support of the vitrimal navantage was not pulled down by the sudden tension of the line.

And also - the installation of new lines, becoming accessible to a larger number of people. Navchannya became simpler, and training of specialists now takes less than an hour.

SIP conductor (self-supporting insulation conductor) is required by the competent conductor. Yogo main task - rozpodіl electricity of the whole snake struma at power lines, those lines of illumination, de voltage should be set to 0.4 to 1 kV.

Provid CIP features

Widely zastosuvannya provіd СІП having taken off the hour of life of the main lines of electric power transmission, and that different vіdgaluzhen to introduce practically at all gospodarskie disputes and private houses.

The cable itself is wired with SIP on a bundle of twists from insulated conductors of different phases, as if made for aluminum and may have an essential zero phase. All phases lived, equipped with special insulation, vikonana won with polyethylene with a sliding vice, zabarvlyuєєtsya in black color, the very same vає stіykіst to raznyh ultraviolet vibrations. At the very center there lived a zero core, the veins are twisted with aluminum needles. Similar.

CIP cable characteristics of that brand

The fallow type of the construction of the SIP can be subdivided into such a view. I would like to know that all the stinks are not less for the design, but for the materials from which the stinks are made.

Provid SIP-1і 1A

The stench is made from the streak-conducting phase veins, the stench is prepared for aluminum. They are covered with thermoplastic insulation, they are practically up to all the bells and whistles, and are not afraid of ultraviolet radiation. My design includes a zero vein, it won't have a character. She lived as if naked, so simply isolated. The letter "A" and means, chi є _isolation chi її not.

Provid SIP 2, 2-A

The Danish type of darts may resemble the design, here the main thing is only in insulation, it is made up of sewn polyethylene. Such cables are installed for the installation of power transmission lines, which can carry a voltage of up to 1000 volts. Provid be famous for its dovgovichnostyu, and building vitrimuvat serious vanity in the face of rich zovnishnіh factors.

One more thing about the first option is that the SIP 1 cable can withstand a temperature of 70 degrees, and the axis is easily visible at 90 degrees. In the process of installing the SIP cable, it is necessary to make sure that it is acceptable. Vіn is not guilty but less than ten zovnishnіh diameters drotu. Read at that.

Wine is made up of one lived. It includes a steel core, the vin is covered with aluminium. If you speak for insulation, then sewing is made of polyethylene. Vіn maє vіdminnі vіdminnі vіdminnі vіdmіnі zahіsnі vlastivostі i zdatny vitrimuvati be-yaké the consumption of ultraviolet light.

As a rule, zastosovuyut yoga in the life of the great power lines, fastening for sip cable is installed directly on the stovpah. The cable can withstand the temperature outside - 20 to 90 degrees.

Provid SIP 4 and SIP-4n

The stench is built up forever from the twin veins, the main feature is the zero vein of the day. Letter of designation in this way it means that the cable is made from an aluminum alloy, because there are no letters, it means that there is a solid aluminum. The insulation is made from thermoplastic PVC, which is resistant to ultraviolet and other external factors.

Provid SIP 5 and 5-n

Vіn May I am similar to the characteristic with the SIP 4 cable. This insulation allows you to keep the temperature up to 30% higher. If we speak for the installation of the CIP cable, then in this plan there are no other sources of power.

Technical characteristics of the SIP scheme

Provіd СІП transshipment and non-delivery

Such darts are clearly seen by them, that they have high-quality insulation, but it’s more richly shorter, lower “Holy” darts, even if you can install them in the most common vpadkas.

In the rest of the hour, they began to win more and more often, even if the installation of CIP cables is simpler and clearer about all plans.

Insulation, yak є between the veins of all wires, building to protect against short circuits in the process of laying on the camps of various spores, or if there are veins between trees. Vіdomі vipadki, if naked darts were brought before the fire.

Just marvel at the peretin cable sip, and you will understand richly.

Plus, it allows you to get people to install such a cable, no matter how qualified. Tse zreshtoy give the opportunity to save the day.

Self-supporting insulation wire is a new generation of cable and conductor products. Zastosovuetsya in the range of 0.4, 1 kV, 6-35 kV:

Dismantling the cable. Video

How to dismantle the CIP cable, you can find out from the video below.

Self-supporting insulated rods are the best solutions for building modern power transmission lines. High operational capacity, low varsity of work life and minimal cost to personnel for servicing the line brought SIP to the leader in cable and wire products. The introduction of insulated new cable brands made it possible to reduce the number of unfortunate fluctuations and emergency shutdowns of butovykh spozhivachiv.

Zalezhno type of brand electrical installation SIP cable for transmission purposes electric struma at the bars with a voltage of 0.4 - 1, or 10 - 35 kV. Lines, laid by cim cable, visibly ventilate into their fronts and do not require highly qualified personnel for installation and operation. What kind of electric drіt CIP can be seen from the first glance - there is insulation on its cores.

Methods for applying and decoding marking

The abbreviation itself, which is victorious as a name, is deciphered as Self-supporting Insulation Provid, which already indicates its main characteristics. Marking on drіt СІП can be applied in an alphanumeric way and with color marks, with additional advances could:

As a result, the color of the marking is stagnant, it should be applied with smugs with a width of at least 1 mm. For self-supporting zero dart vikoristovuetsya blue color.
The alphanumeric characters are visible on the insulation or applied by another method like B1, B2, B3.
The size of the skin mark should be no less than 2 mm of the frill and 5 mm of the frill.
Stand between repetitions of marking - 50 div.
Nulyova lived not to be marked.

Tse important moment- For example, the cable can mother color marking three are alive and alive, blue and red in color, and the fourth is completely black. Nulyova in this way is the one that is more dark, and not marked with a blue smog.

Be-yaké s applied markuvan can be but stable up to a splash of ultraviolet.

Crim for the identification of phases zero wire, marking to remove information about the number of streak-conducting veins and the size of their cross section. The number of signs may look like this:

SIP-2 3x120 + 1x95 - 0.6/1 kV TU 16-705.500-2006

From the point of view, it was understood that the cable is made of three phases, insulated with polyethylene conductors, with a span of 120 mm² and one zero without insulation, with a span of 95 mm². Such a sipіvskiy provіd insurance for voltage up to 1000 volts and broken for TU 16-705.500-2006.

Survival of the SIP

Isolated darts for all the statues overturn their successors, like they did without a protective shell:

Quickness of installation. Instead of pulling 4 more darts, you need to hang only one cable.
The security of the connection - for whom does the plan have electrical supply without insulation? promoted respect that retelly reverification.
Qualification of installers. During installation, it is not necessary to accurately vibrate between the wires in order to avoid a short flicker.
Varity of installation. There is no need for vicarious insulators - it is necessary to take up the cost of vitrate and install them.
The possibility of connecting new points without turning on all the lines - for such wires, special clamps are split, like piercing the insulation and squeezing tightly to the strum conductor lived.

Virobniki declare that the design of the cable makes it possible to practically switch off theft of electricity. About the povniy zakhist, the language is alive, obviously, it’s impossible to go, but the unsanctioned words of truth are brought to them.

Report about the characteristics of this cable to marvel at this video:

Design of SIP darts

To know, how to choose such a cable correctly, you need to be appointed in the first place, which wines are used in constructions. The first symbols of marking, which follow the abbreviation, designate a different type of CIP cable, which is designated as 1, 1A, 2, 2A, 4, 4n, 5 and 5n. The stench will show why the zero cores are built, what is the insulation on them and why the self-supporting power of the cable is safe for the fire (the steel core is in the middle of the zero core or the power of the gale construction)

SIP-1 and SIP-1A

Qi brand electric drotu SIPs are practically identical in terms of their characteristics. The only difference between them is in the presence of insulation on the zero core: on SIP-1 її it is not, but on SIP-1A є. At the same time, the null itself lived a small steel core and may have a larger, even, or smaller cut, lower phase of the rod, a fallow type of brand and recognition of the cable. Insulation material - thermoplastic polyethylene with operating temperature of -60 to +50 C°, without shoddy for its power, which shows the temperature up to +70 C°. Number of lived - 2-4.

SIP-2 and SIP-2A

May the same budovu and strumoprovidnі power, like and darts of the SIP-1 brand, but also the splitting of wines for exploitation in more zhorst minds, which is manifested in the victorious insulation from the sewn light-stabilized polyethylene. The most valuable material with improved thermal stability characteristics is the operating temperature from -60 to +50, and the temperature of the wine can be evenly heated up to +90 ° C and can be vicorated in regions with a cold climate. Number of lived - 2-4.

SIP-3

For other brands of CIP cables, it is necessary to use only single-core cables, which are victorious for power transmission lines with a voltage of 10-35 kV. Vin is made up of a steel core, as well as some kind of entanglement of an aluminum alloy - AlMgSi. This material has high streak-conductivity and mechanical characteristics, and is also more resistant to corrosion. As іsоlyatsіya zastosovuєtsya svіtlostabіlіzovanіv polietilen, scho allows vikoristovuvaty cable СІП in regions with foldable climatic minds.

SIP-4 and SIP-4n

Conducted from the veins of a straight cut from 16 to 120 mm², the number of which can be 2-4 pieces. Carrying power, however, they are divided as they lived. Thermoplastic polyethylene is used as insulation. It can be operated at temperatures from -60 to +50 ° С, with which it is possible to heat up to +90 ° С. aluminum alloy. Also, the marking of SIPN-4 is stagnant, as to say, that the isolation does not expand the mountain.

SIP-5 and SIP-5n

By analogy with the wires SIP-1 and SIP-2, they are coated with the cable SIP-4 and SIP-4n with insulation material, as it is broken from a sewn light-stabilized polyethylene. This allows for a 30% increase in resistance to trivial heating and supercooling, which determines the scope of vikoristannya as for a peaceful and cold climate.

Whether it is a SIP cable, a service term of 40 years may be used and, during installation, it must be observed to a bending radius of at least 10 diameters of the entire cable.

Peretin lived and technical characteristics of wires

In the case of frontal cuts, the obov'yazkovo needs to secure the area of the transverse section and the arm of the dart - qi data can be taken from the corresponding tables.

If you need to connect the SIP cable to the booth, you need to carefully measure it from the street level to the place where the dart is introduced - if it’s more than 25 m, then if the cable needs to be installed, you need to install an additional support.

Briefly about the smut

SIP brand cables are the next generation of wires for repeated power transmission lines, which significantly increase the efficiency of their work. At the by-button zastosuvannі vikoristovuєtsya in the main pіd hour of laying the line of the transformer to the spare part and preparation of the vіdgaluzhenі vіd them. One of the main advantages when vikoristannі є ease of installation and operation, which allows people to work with her without special knowledge of such work. Ale, in any case, you need to remember that all manipulations to connect electrical wiring to the edge may improve the qualification of electricians.
