Installation with a covered insulating rod. Installation of CIP: rules and regulations for safety engineering. Self-supporting insulation wire

⁰

The installation of new electric lines or the reconstruction of old ones will require a thorough approach to installation work, as it is recognized by the rules and standards. For example, in lines with a voltage of 0.38 kV self-supporting darts CIP insulated type. Same way electrical lines guarantee high reliability of exploitation, plus to the whole repair of SIP droids is neobov'yazkovy. Therefore, the operation of the SIP line itself will require only preventive inspections, which are carried out with singing periodicity. The goal of the article is the installation of SIP, according to which rules, installation work is carried out.

Wimogi before mounting, yoga stage

The assembly process itself is repaired by cleansing the trace. It is necessary to see the tree, or the big jacks, as they can stand up along the line, as they can make the installation of the supporting stomp.
Dali carried out the development of the most drot CIP and yoga regulation. Here is more important moment. The provider is not to blame for the construction of concrete supports and metal structures, as well as the earth.

Respect! If a new line is to be laid, then the metal roofings are to be attached to the supports before they are installed. Tse ask the process of strengthening, even if it is on the mountains, it will not be easy. Please note that for whom you will need special equipment, otherwise electricians will have to beat the pazuris.

As soon as the brackets are fixed, then the stinks are installed on the supports at the upper part, which are creaked with a metal line. At the same time, the lines between themselves are reinforced with a special attachment, which is called a creak. Tsej attach, in a first way, close the line, in a different way, tighten it, in a third way, tidy up the excess.
We are preparing the installation of supporting stovpiv at the rear of the preparation of the wells. Here it is important to emphasize the original orientation, so that the brackets of all the stanchions are due to be straightened into one row.
Next, the installation of wires is carried out.

Installation of SIP darts

It is necessary to pay respect to those who have installed that reinforced drota SIP (yogo technical characteristics choose to repeat the installation) only on the basis of technological cards the kind of schemes for which the singing instruments, fittings, fittings and mechanisms are used. The assembly process itself can be carried out at temperatures not lower than +20C.

In front of the CIP, the rope-leader and the rope rollers are roaring. The installation technology is given to ensure the safety of the core itself from the mechanical failure, plus the safety of the long-term operation of the entire electrical wiring. Obviously, dotrimannya vymog tehnіkі sekpeki є є the main rule for the installation of SIP drot. It is necessary to indicate that the darts can be cut and cut by hand without the use of special equipment. ale for whom you may buti insured songs of mind:

Pereriz SIP drot is not guilty but more than 50 mm².
The maximum span between the supporting stomp is no more than 100 m-code.

Before speech, mind you can often be seen in foreign settlements, so the installers carry out the entire process without victorious mechanisms of expansion.

CIP rozkochuvannya manually

At what stages is the manual development of CIP carried out?

The drum is installed from the drotom.
Zdіysnyuєtsya z'єdnanny SIP z rope-leader.
Razkochuvannya double material on rollers.
There is a strengthening of the dart that yogo stretch.
Fastening at the clamps.

And now there are the main points of manual installation. The drum is installed in the first support on the stand no less than the height of the stovp itself, ring out more. The channel-leader creaks to the bone with a camel and an assembly pancho. A roller is installed on the stovp, supported by a belt. On the edge of the intermediate steps, the rollers are installed for additional help.

Now the installation itself. It may be carried out in parallel with the installation of rollers on supports. Tobto they installed a roller, they fixed it well, after which the rope-leader was stretched through it, they gave a bundle of the dart itself. All are afraid of the mountains, so that one person is guilty of staying there. Other practitioners help to turn the drum and feed rollers and tools.

Respect! Rozkochuvannya drum, and, therefore, the cable itself is to blame, carried out at a speed of no more than 5 km / year. As it has already been said more, for which the conductor itself is not guilty of standing on the metal, concrete surfaces, and also on the ground.

Now you can carry out the tension of the electrical circuit. For which a winch is attached to the first step, a dynamometer is installed on it, that toad (tender). Behind the help of the winch, a stretch is carried out, with which the camp is sagging due to special tables. Before stretching, the protilezhny dart must be fastened on the remaining stovp with an anchor clamp. In case of this, it’s not enough for a long time, a vilny kinets, like a victory for a distant connection, or a connection with another country. If the tension is over, then it is necessary to give a deacious hour, so that the conductor sags under the vlasnoy vaga. As soon as the expansion sags, after not changing, you can proceed to the next stage. If you sag zbіlshivsya, then you happen to pull SIP with a winch.

Now, on both sides, it is necessary to fasten the wire with anchor clamps tightly. The harness itself is tightened with clamps. If you can take the winch and p_dryzati kіntsі cable pіd nebhіdny rozmіr. On the intermediate supports of the CIP, the wires from the rollers fit into the underlay.

So, as along the supporting stovpakh, a zero vein, and phases are laid, then between them, obov'yazkovo, so called wedges are installed. The null vein is laid in a zipper, and the phases are installed on a 15 cm stud and fastened with tie-down collars along the sides of the new one. The third phase is fixed on the middle clamp. The vin, at one's own hand, is inserted at a special opening, ruffled at the very closure.

How to eat a lot

In order to join together two ends of the CIP dart, it is necessary to win a special zatyskach. Vіn hermetic and duzhe mіtsny. That is why, before the z'ednannyam, the ends of two delyanok are cleaned and inserted into the zatyskach. Next, the matrix (it is hexagonal) of a manual hydraulic press is pressed against the new one. If something is brought into the hand with a hand. You need to swing until the matrix shrinks to the end.

If it is necessary to carry out a visual inspection of the main line, then it is better to vicorate the tacks that will be pierced. There is no need to clean up the CIP for insulation and conduct direct living. You just need to install a clamp and create the necessary vice. With every tooth of the contact plates, penetrate through the insulation and close tightly with the bare drotom. Special caps are installed to seal the seals.

Visnovok on the topic

The axis of such vimogi and such technology is victorious for laying a repeated line, so that victorious lines are made with CIP, the technical characteristics of which give the possibility of victorising yoga on a dry surface. The instructions for laying the pipe are simple, there are no special boundaries. Golovne - precisely follow the installation technology of insulation self-supporting wires. When bringing up the booth on the yoga wall, it is necessary to install an anchor clamp. Vіn i bude kontsevim kіpilnym element. І rest - do-it-yourself installation of a bolt is not a problem, but it is not recommended. Let it be done by professionals.

Consists of 1 stremoprovidnoy lived round shape yak vikonan with aluminum alloy. СІП-3 is included in the group of protected wires, insulated, light-stabilized PE (black color) with a nominal capacity of an insulating ball of 2.3 mm (for a voltage of 10-20 kV) and 3.5 mm - for a wire protected for peak voltage 35. when dotrimannya minds installation and operation - not less than 25 years.

Indicators SIP-3 are regulated by GOST R 52373-2005. СІП-3 zastosovuyutsya for the organization of lines of repeated transmissions, in climatic minds of UHL and CL with temperature surges in the range of -60/+50*С. Possibility of installation near industrial areas, on sea and lake (salty) shores, near regions of saline beaches. In addition, it is important to carry out the installation of lines at t * not less than -20 * W for the presence of deformations during tension. Provid SIP-3 building vitrimuvat short zamikannya draw 1 s without deformation changes. Zastosuvannya SIP-3 is possible for highways on Rated voltage Vіd 6 to 20 kW and 35 kW.

Testing SIP-3 is carried out with a variable voltage of 24 kW (at a frequency of 50 Hz) with a pull of 5 min, variable voltage 6 kW (frequency 50 Hz). After 10 winding strands near the water medium at t*С +20*С (+/- 10*) СІП-3 is vibrated when applying a changing voltage of 4 kW (50 Hz) with a pull of 5 strands. Provid good vitrimuyut installation vigini - no less than 10 ovnіshnіh diameter, practically unacceptable to the infusion of UF vibrіnuvannya. СІП-3 can be resistant to virgin at t*С - 40 short flicker) up to + 250°С.

The number of darts is directly proportional to the cross section lived. For strands of 50, 70, 95 mm 2 - 7 darts, for strands of 120 and 150 mm 2 - 19. outer diameterСІП-3 with a nominal diameter of strum-conducting lived 25 mm 2 -10.2 mm; 35 mm 2 - 11.3 mm, 50 mm 2 - 12.3 mm, 70 mm 2 - 13.9 mm, 95 mm 2 -15.8 mm, 120 mm 2 - 17.2 mm.

Features of installation of SIP-3

Installation is carried out with tension, which does not exceed 35 N / 1 mm * 2 over the wire. Obov'yazkova umova - saving the integrity of the insulation.
Valid Riven heating SIP-3 for installation time - +90°C.
It is permissible to install SIP-3 with insulated telephone lines (distance - not less than 0.5 m).

Fittings for the installation of SIP-3 are special linear, which allows you to fasten them to traverses and in. metal structures. Attached SIP-3 without polymer, or warehouse for help fenced! Type zastosovuvanih іzolyatorіv - , pіdvіsnі.

To the anchor brackets, which secure the distance gaps between the wires and the supports, the fastening can be fixed on the anchors or the clamps that can be pierced. The design of the anchor clamps is regulated, which allows the SIP-3 to be fixed, no matter how large the diameter. Manual installation for help (without the need to clean the insulation). The method of tightening the “bolt bolt” secures even more securely, resisting up to three truncated overvoltages. A galvanized set for installation similar to a complete set of CIP wires of other types.

Step by step, the lines of power transmission lines with bare wires go near the past. Vono and understood, like a high stink would not be mounted, zavzhd є nebezpeka hits electric jet. Vrahovyuchi, that the power of the struma in such lines is great, even if the stink is to live more than one house, but in an hour the streets and populate the settlements, accidents on these plots lead to serious consequences, even to death. Openings near the sphere of insulation of cables allow you to install a solid self-supporting insulation wire with an okremoyu insulation for dermal strum-conducting and additional drota, as a building vitrimati atmospheric day trivaly hour.

CIP Description

In view of the self-supporting insulating wire and primary twist core power cable without heat insulation. The SIP-1 cable has insulation on the zero-bearing arbor for a day, the marks of the marks may have obov'yazkovu іzolyatsia on all darts. СІП-1, СІП-2 and СІП-3 and їх modifications are introduced by the fact that they are carrying or the single core (like in the SIP-3 winding) is provided with a hard steel core, the colors of the cable brands are vicarious for laying repeated lines of length. СІП-4 and СІП-5 do not wash cores near their veins and can be broken in small places, for example, for the supply of electricity at a separate shield. The insulation of the first and fourth grades of the cable is made of extruded light-resistant thermoplastic polyethylene, as well as for some modifications and for other grades, the vicorist is also made of "sewn" polyethylene. Tsі technologies of bending plastics allow you to take off the coating, the resistance to atmospheric injections and stretching, as well as to the heating of the conductors in critical situations.

Perevagi

The installation of SIP is coupled with bare aluminum-steel wires. Same as with the cables, fastened to carrying cable, vdaєtsya trohi speed up the price and reduce the complexity of installation.

Among the main advantages are the promotion of electrical safety, the independence of the characteristics of the conductor from the atmospheric minds and the obvious ease of installation. Isolation of phase wires does not only protect metal dovkilla, ale and zakhist for otochuyuchy line of objects and іstot vіd vіd vіd vіd vіd vіd elektrichnym strum.

Dodatkovo insulated darts helped to improve the conductive characteristics of the times of ice, like their bare heads, and also they could not be overwhelmed by some wind. Vikoristovuyuchi special fittings and tools for installation of SIP, fakhivets zdatny practically independently zdіysniti the entire process of work, for the obviousness of the installed supports.

Zastosuvannya

Marks of self-supporting wires are made not so for their own sight, as for the sphere of congestion. In general, SIPs are recognized for the transmission and distribution of electricity in the merezh snake struma voltage up to 35 kV. SIP-1 grades are tested in the main overhead lines up to 1 kV. For a special load-bearing shell they lived from aluminum metal with a steel core, such darts of the building vitrimati seriously daunting for a long time.

The installation of SIP on supports of the SIP-1 brand is the most popular when laying critically damaged lines settlements peace climatic zone. For regions promoted vology, as well as in the cities of the mainland, forget about the additional vikoristovuvaty SIP-2, yaki, on the vіdminu vіd SIP-1 with a bare zero vein, insulated on the outside.

Isolation of load-bearing zero dart allows you to increase the electrical safety of the line as a whole, before that, the development of the technology of sewing polyethylene to expand the climatic limits of the installation of these wires.

СІП-3 is installed with one hull, especially for laying high-voltage power transmission lines. СІП-4 and СІП-5 were prepared without carriers, so they were surrounded by short lines connecting specific lines to the main line, as well as carrying out small sections of electrical wiring along the facade and in the middle of the building.

Preparation for work

The installation of SIP on the supports is not necessary in the light of technologies, which were previously discussed. For laying a new line, we need to clear the territory from trees and chagarniks. The next stage will be the installation of load-bearing supports. At this stage, for the convenience of installation, the specialists should fasten the anchor brackets until the support is installed in a vertical position. At the same time, lines made of steel with anti-corrosion dominance, fastened to clamps are made. The fastening of wires to the supports and between themselves is carried out for additional special fittings, which are produced especially for the installation of SIP.

SIP installation rules

Particularly important are presented before the drums are roared: the wire is not guilty of sticking to the ground, or it will be at the installation process, so that the damage to the insulation is eliminated. On the plots over 100 m, only mechanized rotting is carried out directly from the drum installed on the machine. One more feature of the laying of a SIP line is a different block system for cable installation and a step-up stretch. These and other operations require special attachments and tools for installation of SIP, middle knives for steel lines and hydraulic lines for wires, pressing for sleeves, dynamometers, winches and others. The remaining time before the laying of repeated SIP lines is regulated by the PUE (the link of the rules for building electrical installations), as well as GOST R 52373-2005.

СІП up to rozpod_lny shield

Laying electrical wiring in the main power transmission line to a private house, or else vimagatime in the house of the addendum windows at the sight of planning, preparing documents and laying down the contract for electrification of the plant. In the valleys, if the nearest support of the power supply line is roztashovana far away, lower than 25 m from the planned shield was placed under that appearance of electricity, it is necessary to install additional supports for the sackcloth. The best thing is to have a shield on the support itself, and to carry out the supply of electricity to the plot under the ground in a trench.

Vіdpovіdno up to the needs of the householder, you can draw both a single-phase line and a three-phase one. In order to improve the planned vanity, it is necessary to add a re-route. On these plots, sound the vicorist SIP-2A, or the soft darts of the SIP-4 and SIP-5 brands without a carrier lived with a steel core. The fittings allow not only to creep the wire until the wake, but also to conduct small lines of lines right on the facade.

The installation of a railway station is best trusted by the specialists of the company, which will ensure the safety of electricity in your region. They are guilty of signing an act on electrification and sealing the medical equipment. Whether it be a kind of connection, it happens to be able to meet with an energy supply.

Possible pardons during installation

Isolation of the SIP layer to atmospheric pressure, heating and tension, but very sensitive to mechanical pressure. Therefore, it is necessary to protect the laying of wires on the ground and win the rollers without a special coating from polymers. Z'ednannya darts vykonuetsya less between supports, then, as a matter of fact, it is necessary to vykonuvat dart at the places where the darts are fixed. Through a special design of pierced zatskachіv it is unacceptable to re-tack, so other types of zatiskіv are also fenced, to wind like a wire without stretching. The brackets are only secured on one fastening, so it is not possible to twist the SIP sprat into one tie. The skin line can be installed well. Rechecking the tension of the dart on the eye is unacceptable without a dynamometer.

Visnovok

Self-assembly of SIP cable from the stovp to the booth of the zokrema and the lined lines with a halo on the right clumsy at the technical vikonann. It is more important to take it into account to carry out such robits, so fakhivtsy should be trusted to trust the right professionals.

The length of PL-6-10-20kv with wires SIP-3 with skin rock grows. Such lines are called short VLZ, which means repeating the lines from the protected wires. Do not stray from VLI-0.4 sq. repeating lines from insulated wires, for low voltage 220V-380V, SIP-1, SIP-2, SIP-4 are installed.

The most average class of voltage 6-10 kV is the main part of emergency connections. The old LEP-6-10kv were wired with bare wires, in the middle of the night it was calm to the influx of such weather factors, like wind and oxen. And the installation of self-supporting wires from protective insulation allows to improve the characteristics of their safety and reliability.

When changing CIP-3, the number of parameters changes:

Everything is visible from the economic point of view.

Technical characteristics of the drotu SIP-3

Technical parameters and characteristics (retin, nominal strum, Strum short circuit, diameter, mass) of high-voltage wire SIP-3:

Other data - strum, active, inductive opir, voltage drop

The quality of the VLZ, insanely, is deposited in the quality of stagnant wires, but it is also deposited in the form of stagnant fittings. In case of any alteration of materials, you may be prompted not to require the service of the submarine by the term of operation for over 40 years.

Installation of supports for VLZ-10kv

Conductor SIP-3 can be mounted both on new supports and on the necessary replacement of bare wires AC-50-70-95-120. Naturally from the replacement of all load-bearing, roof fittings and insulation. The replacement of the old VL-10kv with a new VLZ with SIP-3 wires is called a reconstruction.

І reconstruction and new life of obov'yazkovo vykonuyut behind the project.

Most of the installation of a new VLZ is started from the installation of anchor supports. Even before the pedestal of the anchor support on the ground, it is fixed on it. required quantity traverse.

To prevent corrosion, and also to the fact that the line is guilty of being unmaintained, it is necessary to victorize the galvanized traverse. Otherwise, you will have to re-elevate yourself on the skin support after a few years, and for the defense of the air, refarbovuvat vitsvili traversi.

The traverse is immediately grounded. To fight through it with a flat seal and a steel bar with a diameter of at least 10 mm (with a span of 78.5 mm2) to the ground outlet on the mast of the support.

On reinforced concrete supports, it is allowed as a fastening, and bolting. On wood, it is recommended to vicorate us in front of the dies.

On the rich anchor supports, the number of descents that are grounded is to blame for at least two. As such, it is possible to vicorate the elements of the late reinforcement of the pre-cast concrete stilts SV-105-110.

The mustache of the metal structures here (strengthened to the pedestal, the traverse itself) is grounded to the beast, through the outlet of the grounding. It’s not necessary to work the okremy to lower the vikings with a rod, but to support the body without a trace to the ground.

Do not wind up the insulators on the traverse on the ground until the moment the support is installed, so as to avoid the slippery damage and the battle during installation with special equipment. Often I have a stand behind the help of a truck crane, or a drill crane machine is installed at a necessary point.

Then we mount one or two pidkosi. The quantity to be deposited according to the scheme of the pipeline and is determined by the project.

The support may be buried no less than 2.3-2.5 meters lower. After that, the intermediate supports are mounted.

Installation of insulators on VLZ

If all the supports are installed, you can proceed to the installation of insulators on them. Moreover, here it is possible to vicorate like traditional porcelain insulators ShF-20, as well as insulators of the new generation IF27 from a special plastic sleeve.

IF27 is more easy to install and allows you to carry out the cutting of the SIP-3 without the presence of mounting rollers. The insulators are mounted on the pins of the traverse or on the supports behind the additional plastic caps KP-22.

Prote not obov'yazkovo skrіz vikoristati suchasnі brands іzolyatorіv. For example, on the anchor supports for the line VLZ іz СІП-3, they have already proven themselves to be old-fashioned glass insulators PS-70E, selected in a garland of at least 2 pcs.

Technical characteristics of insulators from Ensto, Sicam, Niled for SIP-3:

Ensto Sicam Niled

After the installation of the insulators, proceed to the rotting of the core. Most simply, the installation is carried out without intermediary behind the troughs of the IF27 pin insulators.

As simple insulators SHF-20 are victorious, then you will need loose rollers, which are installed on the traverses of the intermediate supports.

Rozkochuvannya drotu SIP-3

On the cob anchor support, the power roller of the troch of the other design is fixed with a bandage stitch. As there are no loops on the intermediate traverses anyway, for which it is possible to move the roller, then it’s possible to screw up the device with a bandage stitch.

In front of the first support on a cable tie or on a cable jack, a drum with a SIP-3 wire is installed.

Rozkochuvannya from the drum is to be blamed in such a way as to turn off the turning of the earth and the pillars of the supports. For whom zastosovuetsya rope-leader. Vin may be made from a synthetic rope with a minimum diameter of 6mm.

A standard drum like Ensto ST204.2060-0030 can easily accommodate 1100m of such a cable.

The main vimogi, which are presented to the rope:

low stiffness to stretching

resistance to ultraviolet and water

dielectric

Even if the length of the cable is not enough, it can be grown between itself with special braces.

On the end anchor support, the motorbike ST204 is fixed. Put a drum with a rope-leader on it.

Motolybіdka ensures the safety of installation hot hour roboti.

A portable rolling machine is installed for the help of a string or lance bandage attachment.

The cable-leader is stretched in a row through the mounting roller on the terminal support, and then sequentially through the intermediate supports, stretching it with the troughs of the pin insulators.

It is possible to roll up SIP-3 without intermediary insulators on intermediate supports, so that the turn of the trace does not exceed 15 degrees.

The rope stretched through the entire anchorage of the boat behind the additional mounting panchokhi is pulled from the dart. Rope-leader is simply connected with a compact knot right up to the loop of the mounting panchokhi. At the same time, on the vіdmіnu vіd drotіv low voltage SIP-4, swivel for SIP-3 is not required.

The edge of the panchokha is wrapped with coils of electrical tape, in order to avoid yoga connection.

One of the installers on the radio, giving a command to another, who manages the motorbike, on її included. Vіn is also responsible for the passage of the knot of the z'ednannya cable with the wire of the air line. And when the dart is tied up, immediately give the command to start the winch.

Provision of CIP services is required equitably, without rivkivs, with a speed limit of less than 5 km/year. When roaming, it is not possible to allow the earth wire and the supports to be torn by the wire.

Preload drotu CIP

If SIP-3 passes through the rest of the power mounting roller on the end anchor support, stop the motorbike. Kіnets drotu zakriplyuєєtsya in the anchor wedge, for example, DN Rpi or SO255.

Technical characteristics and brands of anchor clamps for Ensto, Sicam, Niled:

Pierce the zipper for the electrical connection of the cable loop with the wire, install later, after the residual tightness of the line.

The fitter on the support knows the wire from the mounting roller and disassembles the knot from the rope-leader. Now it is necessary to pull it up at once to adjust the tightness of the rod. Vikonuvat tse sled z obov'yazkovym zastosuvannyam dynamometer vіdpovіdno to assembly tables. You can take advantage (from side 13).

The method of adjusting the SIP tension without a dynamometer, focusing only on sagging behind the arrows, is not correct.

Pohibka can reach significant values. Everything is stale not in terms of accessories, but in terms of a particular fitter. The human factor plays a significant role here, which is not correct.

The conductor must be pulled with a hand winch from the side of the cable drum.

For this drum, three darts are wound, they are fastened on the new installation, the toads are buried, until a dynamometer is attached to their line. And already before the new one, the hand winch's hook is chipped.

The last time the winches zachіpayut to the top anchor on the ground. Like yoga, you can beat the bumper of a vintage car.

The relocation of the weight of the load can be no more than 5% lower than the value indicated in the installation table.

In today's energy systems, the improvement of reliability and electrical safety has become one of the top priorities in development. At the new power transmission lines that are being constructed, SIP rods began to be victorious, so the lines that are in operation are replaced on them. Conduct CIP to stop at the main lines and yoga, and at the introduction of eating at the houses.

Mounting the cable on the steps

Povіtryany lines of power transmission with insulated wires (ВЛІ) or make your own particularity during everyday life. Installation of SIP on supports, like and for all weekday robots, go through the stage of preparation of the territory, which is ploughed at the cutting of trees, bushes, cleared from the crossroads. For stability to the cob of folding, the brackets are fastened to the stovpiv on the ground behind the help of a steel string collar, so as not to corrode, then you can see the stitches.

After the installation of supports with brackets, proceed to the stage of folding VLI. The temperature of the actual winding may not be less than 20C. As it was planned more, the technology of installation of CIP may be special when rozkochuvannі drotіv, tobto. it is necessary to preserve the integrity of the insulation before commissioning. Drums with wires are installed on the machine, and vicorist special roller fittings and rope-leaders are evenly distributed along the supports.

Manually soldered wires

The process of roaming with drums by hand is only possible in the fall, as if the life time did not exceed 100 m, with a change in the skin phase, the skin phase was not more than 50 mm 2, and also on objects and territories with a span height of less than 50 m.

Manually rozkochuvannya and installation of CIP for the skin proletion is the same and pass at the kilka of the stages:

Cable termination

Having completed the installation of the SIP on the supports, we begin the journey to the line of life, depending on the introduction to the object or wake-up.

The connection to the vital main line is to be connected for additional tight seals. For which the insulation of the conductor is removed, at the ends of which they transfer the installed clamp, and for the help of the press they press until the second contact. For the presence of non-insulated conductors in the main lines, they are brought in by such a rank, de zatyskachiv can be beaten with special sleeves with sealing material for non-insulated conductors.
The clamps for wiring are vicorated for connecting the inputs to the main lines from non-insulated conductors. At the main vіdgaluzhennyah, it is recommended that vikoristannya conductors live without living, what they carry, with which they all lived to be fastened with one steel clamp in a clamp.
In times of impossibility to remove the isolation of the conductor, when connecting the introduction to the object, put a clamp for piercing. The zatyskach allows you to pierce the insulation to the very edge while tightening the bolted joint, so that you can control it with a calibrating head.

Connecting the introduction of a wake-up line

To bring in the introduction of a living accommodation manually to the main line, the number of the same veins must be set to 4. The living accommodation can be added in two ways.

Ground method from stovpa

This way of transferring the internal conductors of the living quarters to an adjacent support, as it is necessary to stay at a distance of no more than 25 m from the object. In the other case, you need to install an additional support (stovpa) for 10 meters from the object. The height of the span of a double dart is to become more than 6 m.

Before Tim, how to spend the day insulated darts I will hand over the CIP for additional help, it is necessary to conduct wiring along the walls and the facade of the building or the living quarters. For zhorstkoї fixation zastosovuyutsya anchors zatiskachi, є є loop with a bracket (on the walls they are mounted behind additional dowels). Minimum distance between the surface of the earth and anchor clamps to become 2.75 m.

After the introduction of the conductor until the wake of the living quarters. When rotting electrical shield CIP calls are connected without delay until the next.
