Markuvannya electric darts and cables The current range of wires and cables is wide. Buyers' representations of a great range of cable and wire products of various structural design lived, as well as various insulation coatings. As a rule, all conductors and cables can be specially marked, as if showing the characteristics of another product. Below we will decode the most widely used brands of wires and cables.

Marking of electrical cables

The current assortment of wires and cables is wide. Buyers' representations of a great range of cable and wire products of various structural design lived, as well as various insulation coatings. As a rule, all conductors and cables can be specially marked, as if showing the characteristics of another product. Below we will decode the most widely used brands of wires and cables.

Letter-digital marking of cables and wires

Markuvannya electrical cables and wires are carried out by letters and numbers. We can look at the short letters, so that they are marked, so that they can be used for identifying cables with polyvinyl chloride (PVC) and humic insulation according to GOST 16442-80, TU 16.K71-335-2004, TU16.71-277-98.

"A" (first letter) - designates the material lived, in the case of aluminum, and for the presence of this letter, the material is mid.

"AC" - aluminum core with an additional cable sheath made of lead.

"AA" - aluminum core with additional aluminum sheath of the cable.

"B" - to tell about those, that this cable has armor, as it was wound with two balls of steel line with anti-corrosion coating. If the letter “n” stands, then the manufactory may look “Bn”, then the steel casing may have a special covering, as it does not support the mountain. Letter "b" - vikonan armor with profiled steel lines.

Marking of electric cables and wires "B" - first (for the visibility of the first "A" - friend) - polyvinyl chloride insulation, friend (for the visibility of the first "A" - third) - polyvinyl chloride sheath.

"G" - for example, marking - "bare" cable, which does not have a twisted curve. Like the letter “G” stands on the cob of marking, the whole cable is victorious in the girsk industry. Ryadkov's letter "g", as a rule, is put in the end of the marking and to tell about those that the metal screen is sealed to the cable with a water sealing line. Marking "2g" - the presence of an additional aluminopolymer line.

"Shv" - the presence of a protective sheath to the cable at the look of a pressed polyvinyl chloride hose. "Shp" - a hose made of polyethylene, "Shps" - polyethylene, from which the hose is made, which is self-extinguishing.

"K" - on the cob marking about those that the control cable. “K” for example, marking - the armor of the cable is vikonan with round steel darts, over them the robes are covered with a twist.

"C" - lead sheath cable. "O" - Vikonan sheath over the skin phase of the cable.

"P" - insulation of the Vikonan cable with gumi. If there is a letter H in front (marking HP), then the insulation of the cable does not support the top.

Marking "ng" for example - does not support the mountain.

Numerical values ​​for marked cables show the number of cores of those spans. For example, 3x2.5 - three lived with a web of 2.5 square millimeters.

Apply the decoding of the alphanumeric marking of cables and wires

For accuracy, we will draw a spear of butts for marking the widest brands of cables.

AVVGng 3x4 - tri-core cable with aluminum veins with a 4-square peretina, with cladding and insulation with polyvinyl chloride, without a shackle curve, which does not support the fire.

PVG 3x2.5 - a three-wire cable with mid-wire peratin 2.5 squares, with polyethylene insulation, PVC sheathing, the cable does not have a protective curve.

ASB 7x2.5 - a seven-core cable with aluminum conductors with a 2.5-square span, in lead sheath, the cable is armored, as it is wound with two steel lines, which does not succumb to corrosion.

Cable VVGng-LS English letters: HF and LS - stench about the low rate of sighting gas and dima is clear. For example, VVGng-LS-HF.

The marking of wires in the singing world is similar to the marking of cable products, but there may be an identity.

Let's put the marking of the widest wires and cords in line with GOST 7399-97.

SIP - self-supporting insulation wire, the insulation of which is made from light-stabilized polyethylene of the sewn type.

BUT - aluminum wire, which does not have an insulating coating. Denmark is being prepared with a lot of darts.

AC - steel-aluminum wire, which does not have an insulating coating. Structurally, it is built with okremih darts, yak roztashovani on the steel core (the basis of the darts). PVS - wire with PVC sheath and insulation, flexible, with twisted conductors.

SHOG - cord with polyvinyl chloride insulation, with parallel wires, especially flexible.

PPV (APPV) - wired with medium (aluminum) flat conductors, with single-ball insulation made of PVC.

Color marking of cables and wires

Crim of alphanumeric marking of wires and cables, іsnuє color marking. Below, pererakhuyemo kolori, with which they mark the proof of that vіdpovidne recognition lived:

blakitny - zero (neutral) conductor;

yellow-green zahisny guide(grounding);

yellow-greens from black marks - a grounding conductor, such a connection from zero;

black - phase conductor.

In addition, it is allowed to add a different color to the PVE for the phase conductor, for example, brown.

When attaching a cable, put respect on the color of the marking lived, to that one, in fact, it may not be true to the vimog. Vidpovidnist zabarvlennya lived zagalnopriynyat standards - tse, persh for everything, zruchnіst during installation and further maintenance of the wiring.

In every case, the color marking of the veins does not add to the quality of the cable and conductor products. To that, if you attached a cable (wire) with non-standard wires, then before installing it, you will have to decide which color will be recommended to which conductor.

Power cable VVG - choice

The VVGpng LS cable can be classified as a power cable, which does not rise in the mountains, with low gas emission, near a flat wind tunnel. The Danish species was used with a medium power cable, which could be two single-core or rich-core lived with a span of 1.5 or 2.5 sq. mm., or three lived with a span of 1.5; 2.5; 4.0; 6.0 mm2 With the method of defending the isolation of conductors from the aggressive dovkilla the cable has an internal extruded sheath, superimposed on twisted insulation, lived from composite polyvinyl chloride with reduced dimovidlenny. The inner shell is applied more importantly with the method of filling gaps between the rimmed veins. The thickness of the inner extruded shell is 0.3 mm or more. Without internal sheathing, it is allowed to make cables with sectoral rotting of the cores, with this twisted insulation, they lived to the beast, but they overlapped with lines (one or two) from a thermally bonded fabric or polyethylene terephthalate slick. Outer casing made of composite PVC of reduced fire safety. For cables, which can be cut through round strum-conducting conductors up to 16 mm2, the outer sheath is broken at the same time from the fillings of the gaps between the rimmed conductors. This brand of cables is laid in cable boxes and applications, at industrial and office days, at nuclear power plants of classes 2, 3 and 4 according to the classification OPB-88/97 (PNAE G-01-011-97). The temperature range of the superfluous medium, when the VVGpng LS cable is allowed to operate, is set to - 50 °С to + 50 °С. Category of placement for the VVGpng LS cable: 1 and 5. Climatic vikonannya: UHL and T (cables with the “T” index (for the tropical climatic vikonann) stiykі to di tsvіlevih fungi). Service lines for VVGpng LS cable: not less than 30 years.

Marking for VVGp ng LS cable

Decoding of the VVGp ng LS brand: Vinyl, Vinyl, Gnuchky, flat, sho not rose all the way, with reduced smoke (Low Smoke). Marking of cables VVGpng LS consists of cable brand designation and two digital values. The first number in the marking means the number of lived at the cable, and the other - the cut lived, for example VVGpng LS 3*2.5.

They use one type of one cable VVGng LS p, cable VVGng p LS and cable VVGpng LS.

A lot of people, especially quiet, who have recently been tied up with electrical wiring and cable and conductor products, often introduce into Oman a different brand of cable VVGpng-LS. Zokrema, the letter "p", which means "flat", can be just like the letter VVG, so after the designation of the additional characteristics of the cable - "ng" and "LS". In this rank, there are at least three widest options for writing the brand of this cable. Ale all tsі znachennya prihovuyut the same cable, just in the interpretation written for the versions of different trading organizations and navіt іnоdі vіrobniki. From the point of view of the author, this article is the most correct, it is written VVGpng-LS, the form of the cable follows the abbreviation, which means design features, overnight viperedzhayuchi knowledge of operational characteristics.

Cable VVGPNG LS Construction.

At the heart of the design cable VVGpng LS can lie two single-core or rich-core lived with a reline 1.5 or 2.5 sq. mm., or three lived with a retina 1.5; 2.5; 4.0; 6.0 mm2 Colour: white/yellow, blue/green, red/raspberry, brown/black. Digital: 1, 2, 3, 4. On top of the insulated twisted conductors with composite polyvinyl chloride with a decrease in dimovidiles with a method of filling a gap between the same conductors, an extruded inner shell is superimposed. The thickness of the inner extruded shell is 0.3 mm or more. Without internal sheathing, it is allowed to make cables with sectoral rotting of the cores, with this twisted insulation, they lived to the beast, but they overlapped with lines (one or two) from a thermally bonded fabric or polyethylene terephthalate slick. External sheathing of the Vikonan cable with composite PVC of reduced fire safety. For cables that can be cut through the strum-conducting cores of a round shape with a cross-section of up to 16 mm 2, the outer sheath is double-walled from the fillings of the gaps between the rimmed cores.

Zastosuvannya cable VVGpng LS

The VVGp ng LS cable is installed with the method of transmission, as well as the distribution of electrical energy in stationary electrical installations, insurance on changing voltage nominal 660, і 1000 (frequency 50 Hz) or constant voltage outweigh the change by 2.4 times. Cable VVGpngLS zastosovuetsya as for laying in wake-up calls, and on open air, including windings. It is allowed to lay this type of cables at cable spores and premises, at industrial and office buildings, at nuclear power plants of classes 2, 3 and 4 according to the classification OPB-88/97 (PNAE G-01-011-97).

VVGpng LS cable Specifications.

The term of service of wires VVGpng LS becomes less than 30 years from the date of preparation. Warranty term of operation - 5 years. The validity of the real term of the cable service as declared is guaranteed by the contractors only for the understanding of the need to understand the scope of transportation, storage, installation and operation.

The maximum allowable temperature of three-valve heating of the cores: 70 degrees. Celsius.

The maximum allowable radius of the winding during installation: not less than 10 outer diameters for single-core cables, for multi-core cables - 7.5 outer diameters.

The minimum permissible temperature of the inner core, for which it is possible to install (installation) of the VVGpng LS rod, is -15 degrees. Celsius.

Type of climatic wire VVGpng LS: UHL and T

Provid VVGpng LS can be operated at a temperature of the necessary medium from -50 to 50 °C.

Provid VVGpng LS є stіykim up to the injection of increased water content (up to 98%) for washing, so that the temperature of the middle medium cannot be exceeded +35 deg. Celsius.

Cable VVGpng LS. Price

When laying down the supply of this type of product, like cable VVGpng LS price lie in a large group of factors. The first role, insanely, plays a seasonal role - a show that is formed from the exchange prices for the copper rod and the dynamics of a calm drink. Remain without a middle legacy of the seasonal nature weekly work that wild economic and political situation. The variability of the brand of the cable, like and the variability of whether it is your own cable and conductor products, to lie in the terms of delivery and obsyagiv, like to recognize the deputy. So, for example, if you buy a cable VVGpng LS wholesale, then the price of one meter of cable (or one product) will be noticeably lower for you, lower when purchased in retail. According to the above statement, give an unambiguous statement on the power supply "how much cable VVGpng LS?" just can't. For a specific skin type, the variance will be individual. Project managers and managers of the SpetsElectroStroy company have a great practical experience in the electrical markets, so they can always encourage you to find the best way to supply you with the products you need. Depending on the accepted terms of the product, we will be safe for you to get the cable VVGpng LS the kind on zamovlennya.

What is a power cable?

More from high school lament my guilt, that the electric strum, which is victorious for the life of all electrical appliances and equipment without blame, is to order the charge of particles (electrons) by the hand. It is obvious that such a phenomenon is trapping everywhere, but for the sake of yoga for the smallest scale, it is necessary to create songs of the mind. It is essential to choose the form, construction, and strum-conducting medium, which will allow you to not only economically transfer tension to the calm, but also safely.

Today's hotly-accepted form-factor cable is a multi-wire conductor, laid in zahisnu isolation with linear and concentric roztashuvannyami veins. The classification of cable products is subject to various criteria, but one of the most important of them is functional recognition. How to find out about the need for transfer electric struma industrial frequency and voltage, then vicorous power cables, for example, VVG-KhL, VVG-Png, VVGng-HF and so on. rozpodіlnogo pristroy(VRU, GRSHCH) that kіntsevogo spozhivach (promislovo obladnannya, by-button technology, lighting fixtures and etc.). The nature of the organization of the plant is to lie in the minds of the exploitation, the cable is too thin.

Wire marking and decryption

Leather from serially vibrated cables can be treated with core material, insulation, and additional elements. Tse allow the picker to carry out research for specific minds and exploitation. For the purpose of recognition, you need to put in additional marking. Її deciphering can be rich in information about the components of the finished product, the presence of specific balls, for example, armored, the method of laying (on the ground, on the ground, on the frame, etc.), the number and cost of that resection lived. Other indications, for example, a running meter cable, are vibrated at the tables.

Some early guessing stamps power cables(and other similar products tezh) dіє spherical principle of organization of recognition, starting from the internal. Obviously, for VVG-KhL, VVG-Png, VVGng-HF, then, the first letter is responsible for the material of the strum line. But here, according to the standards, there is one peculiarity: this letter can be obvious or attached (like in our mind). As the material for living is aluminum, then the symbol “A” should be placed on the back of the marking. As if on the back of my hand, be it another (for example, for VVG-KhL, the symbol “B”), then it automatically means that the midna lived. There are no other options for core documents and technical standards, and the shards and materials of today are practically uncontested in the mass variety of zavdyaki to their physical features. Pitoma vaga tsikh metal vіdrіznyaєtsya practically vtrichi, and tse means that the cable is of the same length and peretina with a mid-range residential important vtrichi more than aluminum.

• B (persha) - stremoprovidna midna lived maє primary polyvinylchloride (PVC) insulation. Zalezhno vіd prichennya lived її kolіr can be different. For example, the phase wire can be brown insulation, zero - blue, grounding - combined yellow-green;
• B (friend) - sheathing of insulated cores made of similar PVC;
• G - the appearance of the sour veneer (the outer shell). In the electrical lexicon, tse means that the cable is “naked”.

This is a complex of signs that form the basic sign. Fallow in the form of a quantity of the type of balls, it may be short-lived, so that we can honor the additional signs. For example, the symbol "B" indicates the presence of an armored ball and the possibility of laying in the ground. Following them, they point to the same modification, unique characteristics:

To save money on electricity bills, our readers are happy to see "The Economist Energy Electricity Saving Box". The number of monthly payments will become 30-50% smaller, lowering the economy to a lower level. Vіn tidy up the reactive storage space, after which the profitability decreases and, as a result, the stream of comfort. Electrical appliances cost less than electricity, reduce costs by її payment.

• HL - cold resistance of the cable, which indicates those who are guilty of extreme temperature tactic minds;
• P - flat shape of the cable (the okremi lived fit into the shell not by concentric, but by linear methods, a row);
• ng - vicorist materials and this yogo combination does not support the mountain;
• HF - literally, in translation from English, tse means "free kind of halogens". In practice, this term stagnates not to all chemical elements of the 17th group, but only to chlorine after the great rahunka. In the combustion process, such a cable does not see the toxic products of the furnace that chlorine is removed.

And now you can go to a detailed review of the modifications of those characteristics.

Description of the cable type VVG-KhL

For the transmission of electrical energy of industrial voltage and frequency at a height of up to 4.3 km above the sea level, you need special wires, such as VVG-KhL. Vikonuetsya like in single-core, so in multi-core options. In the rest of the year, the twisting method is used. The very shape of the VVG-KhL lived either as a classic round, or as a sector. Rozmalovka internal insulation made of PVC - classic. Vіdminnіst mаyut cable over 70 mm 2 - this is where digital marking comes into play.

Okremo slid see chotirigilnі cables VVG-KhL, in some cases, on vіdmіnu vіd іnshih modifications, zero and grounding rods may have a smaller pererіz.

Like the marking of VVG-KhL, the outer shell is crushed from cold-resistant PVC-compound. This allows you to twist the cable at low temperatures (up to -60ºС) and high moisture (up to 98%).

The laying of cables VVG-KhL can be done in a different way, near mines, collectors, bridges only. If there are no reservations, the possibility of mechanical assistance may be reduced to a minimum. Laying near the ground does not hover. When installing, it is necessary to ensure that the minimum radii of one or more VVG-KhL wires are installed, 10Dn and 7.5Dn.

Cable type VVG-PNG

This type of conductor products is victorious in the minds, if it is necessary to minimize the possibility of expanding it. The prefix "ng" in the designations of VVG-Png means those materials that are beaten during preparation, do not support the fire.

The technical characteristics of voltage and frequency are heat-transmitting and become 660/1000 at 50 Hz. Strumoprovidní lived from midi to round the shape of the periphery, but not in a concentric way, but in a row, in one plane (“P”). As a rule, the number of people in serial variability is equal to 2 or 3, and the length of the okremoy lived - from 1.5 to 4 mm 2.

Laying of VVG-PNG on open air, in premises, cable racks. It is not recommended to vicorate trenches near the ground through non-armored trenches.

Cable with HF prefix

This type of power wires vicorist materials, like halogens, zocrema, chlorine. Therefore, in the mass production, it is most common to vicorate the modification of PPGng-HF, and not VVGng-HF. The difference between them is based on the material of insulation and the outer shell: vikonana is not made from PVC, but from polyethylene or other polymers.

They lived PPGng-HF, like in the forward slopes, vikonan from midi. Їx quantity can be changed from 1 to 5 with a 1.5 ... 50 mm 2 transition, which naturally flows into yoga. The cable for such a device is not armored, but it means that the laying near the ground is turned off.

How can you put more than what has been said above, deciphering the designation of cable products, maybe a lot of information about its design, the presence of an armored ball, the possibility of installation in the ground or in the ground, a pet vase, etc.

Perhaps, there is no living room, where electrical cable products would not be stagnant. Living houses, office premises, apartments, factory workshops - all the stench is covered with kilometers of darts different recognition. I, obviously, the heart of the crime of its main goal - the safety of the supply of electrical energy, due to the fire and electrical safety. One of these varieties is є. Let's look at what is being sought after this abbreviation.

Sob nadali good razbiratsya in mental cognitions conductor products, which we will take, look at, how to find options, what the letters and numbers mean in the name of the dart. As the first place in the sign has the letter A, then the material for the veins is aluminum. Like the letter A in the day, they lived prepared from the midi. In our case, it is possible to the right with the middle veins.

Another letter (for our mind it will be the first) means the material of insulation lived. The following definition is accepted:

• the letter P stands for polymer insulation;
• the letters Pv denote polyethylene;
• the letter is taken to mean polyvinyl chloride (PVC).

• already known to us, the letter denotes polyvinyl chloride;
• the letters Shv indicate the presence of the suffocating hose;
• letters Шп indicate those that the hose is made of polyethylene;
• letter P to talk about the polymer shell.

We will then indicate the degree of protection (reservation cable no). The letters B seem to indicate that the cable is armored, the letter G indicates that the cable is without armor, that is naked. For example, the indications indicate the steps of the fire safety:

• the absence of literal designations indicates those who, when laid alone, do not support the mountain;
• the sign of NG indicates that the group arrangement of such wires does not support fire;
• with the signification of ng-ls slіd, scho krіm vyschezaznachenih authorities, є reductions in dimo-i gazovidіlennya;
• Krіm tsgogo, it is possible to designate ng-hf, which indicates the presence of a widening of the horn and corrosive-active sights at different times with a group laying of wires.

In such a rank, perhaps more advanced: the VVGng cable is a power conductor, which may have lived in polyvinyl chloride insulation, the same kind of insulation, and do not support the mountain with a group laying of conductors.

Krіm hovering over the designation, can be present letters fr, which indicate the fire of the dart, and the letter P in the very end of the marking. Vaughn means constructively better, the very ones that the VVGng P cable is flat.

Technical characteristics

Let's take a look at the main technical characteristics:

• cable for operating voltage measures 660V and 1000V. At times, more insulation is needed. Mere frequency 50 Hz;
• the maximum operating temperature of the door is 70 degrees Celsius. The temperature of the fire is over 400 degrees Celsius;
• operating temperature range with a moisture content of more than 98% to become -50 to +50 degrees Celsius;
• the minimum temperature of the navkolishny middle during the installation of the door is up to -15 degrees Celsius;
• the warranty term of the drotu becomes 5 years, and the term of service - 30 years.

The next step is to indicate that the minimum perimeter lived to become 1.5 square meters. mm. And the maximum amount of time to lie down in the form of a living. So for round veins it is worth 50 sq. m. mm, and for segments reach 240 sq. mm. They may have lived as single-handed and rich-handed. Such technical characteristics of recutting allow vicoristing cey virib for different strumovyh navantagen including dosit znachnі.

Electric motors and fittings in private booths and in factories are connected to electrical wiring with different types of cable. The type of strum at the conductor is changeable. Widely known cable VVG. Design organizations often lay the foundation for the specification of projects of all projects. Decryption of VVG wires helps the pickers pick up the required material. Special designations allow you to distinguish between darts. VVG, the decoding of which is applied to the insulation, everything will be told to competent electricians.

How can I see the VVG cable?

The abbreviation for decoding the cable is to provide information about the preparation. You will be advised that it is recommended to connect the switch and in some way to lay it, either in a modern or underground way, it is possible to win and if the temperature is acceptable again, it is recommended.

Sales of materials, which are victorious in energy security, that great assortment of wires for insulation and construction, give the opportunity to purchase the materials of your choice for these products, as you need. A novice electrician and an ordinary spozhivachev will be well known, how many different brands of VVG cable with decryption є on the sales market.

Naming the cable VVGng Ls, it is deciphered, carrying information about those who see the minimum number of dima during the next hour.

The VVGng FrLs cable does not absorb fire in wet half-light. Through the insulation, which melts, the smoke is minimal.

The offensive appearance of the product is with the decryption of VVGng Hf. If the wine is subjected to a thermal injection, for example, it will be an hour to burn that melted insulation, gas during the day. Conducted not corrosion.

Remaining view of the drotu VVGng FrHf can do everything best features laying more cables.

Product insulation

Before the insulation material, which is victorious in the production of cable products, there are special benefits, including fire service. Material PVC (polyvinylchloride) has one particularity in terms of application to other polymers, which must be used for the preparation of plastic products. PVC products do not interact with fire. Zavdyaki tsіy power polyvinylchloride zastosovuєtsya when prepared insulation covers for cable.

Materials for making cables:

1. Basic look insulation materials VVG - double insulating cover. Material PFC (polyvinylchloride). Dodatkova isolation daily.
2. The insulation of the middle cores of the VVGNG cable is made from non-combustible PVC materials.
3. Halogen-free PVC, which is used as an insulating material for VVG Ls wire, does not see dima when melted. Vykoristovuєtsya for the installation of electrical wiring, in places of crowding of people.
4. Pulling the cable, de mozhlive slept yoga, vikonuetsya s brand VVGng FrLs. Represented by isolation є vognestіykoy and do not see unsafe Dima. Cable with decryption VVGng FrLs is vicorated for closed for critical installation with a high level of fire anxiety.

Let's take a look at the marking of the cable. Familiarize yourself with the VVG decryption of the dart:

P - polymer insulation of the core.
. B - polyvinyl chloride.
. PV - a group of materials, which is based on polyethylene.

Deciphering the offensive letter designation allows you to know about the warehouse of the insulation cable.

B - ovnishnya іzolyatsіya z PVC.
. Shv - the zahist is alive at the sight of the hose.
. P - the name of the polymer insulation.
. Shp - insulation of zovn_shnya from a polyethylene hose.

Zahist cable VVG (deciphering below) in the form of a mechanical error may have its own designation.

B - reservation cable with hard covers.
. G - flexible cable. There is no special zahist.
. Provid VVG PNG, the decoding of which is presented more and clearly indicates its recognition.

Peretin lived to the cable that yoga meaning

When installing electrical tethers it is important to correctly select the cut of the strum line. Transfer to the electric jet to lie down without intermediary through the wire cut. Engines and fittings, connected to the yard, save electricity. Electrical distribution when the stream passes through it, it starts to heat up. Heating the wiring in case of an incorrectly selected cut could lead to a mimic fire. It is necessary to take 30 more wire peretin. At the cable, spend the struma, yakі it is necessary to transfer the back of the leg. I’ve attached the wiring to the booth, popovniti spend at the future smoothly.

Pristriy VVG PNG a

Crossing the cable of the same type from 1.5 to 16 squares. The number of wires for a new one is two or three.

Meaning of symbols of darts:

1. B - lived in PVC insulation.
2. B (friend) - PVC-sheathed cable.
3. G - zahist cable vіdsutnіy.
4. P - roztashuvannya lived parallel, flat.
5. Ng - the mountain of insulation is not supported.

Rozrіz cable VVG-PNG A:

• vein of medium round shape and odnodrotyana of the first class;
• insulation material - polyvinyl chloride;
• color wires;
• PVC sheath, which reduces the power of the mountain.

The main stopover for this type of cable is at the transmission and distribution of electricity snake struma with a frequency of 50 Hz and an intensity of 0.66-1.0 kV.

VVGozh cable

Great drink in the sphere of cable production, we use a cable made of peratin 3x4 brand VVGozh. Warehouse of this copper cable includes lived, covered with PVC insulation.
Decoding VVG ozh:

1. B - insulation is alive with vinyl.
2. B (friend) - vinyl shell.
3. G - naked.
4. Ozh - odnodrotyane lived.

Cable design VVGozh

Lived to conduct a strum, midna, first or another class of GOST 2483. The shape lived was round or sector-shaped. Belt insulation made of PVC plasticizer, lowered on hot fire. The cable was twisted with two, three, three and five lived around the PVC core. The outer shell of the cable is made of PVC-plasticizer, which does not support the mountain.

Cable insulation made of polyvinyl chloride. Carried out to a cable of a different color. White man. Blue and green. Black color or brown, red and raspberry.

Scope zastosuvannya cable VVG PNG

The operation of the cable is allowed on land, near rivers and lakes. Zastosovuєtsya at temperatures from -50°С to +50°С. The height of laying above the sea level is allowed at a height of 4300 meters. You can lay the cable in the ground, in the water, on the ground, on the stovpah and on the walls of the building.

All other characteristics can be seen to the VVGozh cable, decoding what to tell us how to prepare wires from the middle wires with a 3x4 peretina. Vykorist yogo in the pivnіchnyh areas and in areas with a peaceful and tropical climate.

With the decoding of the VVG, one can lead along the walls of the future. Laying is carried out along the stovpah and pіdvіskah on the cables. Vykoristannya cable this type allowed there, de vidsutnya threat to sleep. Lay yoga more on plastered walls or walls, or on plasterboard walls.

At times of threat of mechanical damage, the cable must be protected. Serve as a guardian beforehand steel pipes, in a yakі wind up drіt. The most true such laying is in wooden booths. The corrugated sleeve, which protects the divorce, is widely worn in everyday life. Zastosovuyutsya different cable channels to zahistu. Laying strobe products with decryption of VVG cable is not recommended. For whom is it better to visit the conductor VVGng. Vіn creations for attached holding. Є recommendations normative acts, which have the rules for installation work for the VVGNG cable.

Rules of zvnіshnіh robіt іz cable products

When laying the VVG squirt line near the ground, it is necessary to follow the rules. Protecting the cable of the same mind. Vykoristannya concrete boxes, cable channels and pipes zapobіgaє mehanіchnіchnіch poshkodzhennym cable. Widely zastosovuєtsya at the given hour, the signal zakhist zamіst chervonoї tsegli, which vikoristovuєtsya earlier. Vikonaniy zahist at looking at polymeric plates, like you can see characteristics that do not collapse.

A squeaky pillow is squeaking near the trench. A cable is laid on it, and the earth is piled and tamped on top of it. The tovshchina of the balloon can be no less than 20 centimeters. After that, as soon as the cable is laid, the plates are laid, so that they also sizzle with squeak. A signal line is laid on top of the pipe, which is ahead of the presence of an electric cable.

Laying an armored cable is the best solution for earthen robots. The variance of this installation is higher than the variance of the VVG cable. The term of exploitation of the same, but also the guarantee of the protection of damage from the armored dart of the wealthy.

Having become aware of this article, a simple buyer, not fahivets, correctly pick up the necessary cable. Due to the fact that the market today promotes an impersonal view of that type of cable, without singing knowledge, it is even more difficult to choose a choice. If there are any doubts when buying, it is better to consult with the seller of electrical wires. It is even more important, even if it has been carried out to deposit the safety of all the baggers.
