Provid SIP: what is it, characteristics and technical advantages

The subject of our current research is CIP. What is it, you can understand the names. Vin is a bundle of insulated phase conductors, zero-bearing twists. As an insulating material, it is made of polyethylene, resistant to ultraviolet vibration and atmospheric intrusions. Conductor of preparations for aluminum or yogo metal. At the central part of the zero cross section, a steel core lived to pass, and coils were twisted to the right.

It is installed in the power transmission lines, at the power electrical circuits it is vicorated for lighting at a voltage of up to 1000 V.

Perevagi

Various SIP-constructions appeared as an alternative, fixed on insulators. Your experiences are as follows:

• maintenance cost is cheaper;
• more stable parameters for transmission of electricity;
• resistance to atmospheric splashes: significantly less sticking of snow and ice; high chemical resistance of insulation to aggressive mediums;
• simple and fast installation, no need for technical equipment;
• reactive losses are reduced in pairs with traditional wires on insulators;
• lowering the number of hundred with the help of illegal connections;
• a day of short chimes for an hour of winding up of the wires under the windy wind;
• For real exploitation minds, you can choose the optimal type of drone.

Dart brands

Provid CIP - what is it? You will be more understanding, so you will appreciate all the sight of the guessed viroba. Different brands are considered structurally and according to materials.

1. SIP-1 may still live in phases, but zero-bearing winds. In this variant, the null vein is bare, and in March with the index "n" it is insulated.
2. SIP-2 is prepared in the same way, but insulates and saves high mechanical and electrical power at a temperature of 130 0 C (the best material takes shape even at 85 0 C). Virobi tsієї brand vikoristovuyutsya in the minds of active atmospheric infusions.
3. СІП-3 is formed in total with one lived with a steel core and can stagnate in the case of power lines with a voltage of up to 35 kV.
4. SIP-4 and 5 - the chances of avenging the strum conductors lived for zero carrying capacity. Yakshcho є znachennya "n", tse to speak about those, scho material є alyumіnієvy alloy. Stamps of wires are vikoristovuyutsya for the creation of vіdvodіv vіd LEP to living budіvel and for illuminating merezha. Krіm them, also you can zastosovuvatisya іnsha brand, for example, provіd СІП-2х16. The rest of the number means the minimum size of the cut in square mm.

The axis of such a wine is different - provіd CIP. What is it, you can see the manifestation. To put it in simple terms, as we can see, it can be considered as a cable product, divided into three systems:

• with naked neutral;
• from insulated neutral;
• self-supporting system.

Let's take a look at the dermal view of the report.

Naked neutral system

SIP first appeared in France and Finland in the 50s, and after 30 years it became widely known in Russia. Tsya system revenge:

• one bearing neutral without insulation with aluminum or metal with a steel core;
• insulated phase conductors made of aluminum (type 1 to 4), twisted around neutral.

The system includes domestic brands SIP-1,2 and the Finnish analogue of AMKA.

The neutral is zastosovuєtsya for pіdvіshuvannya jgut that bears all the advantages in the form of tension and mechanical influx of zvnіshnіh factors. Її ground on a skin support to prevent unsafe life from potential, which can be caused by phase imbalance.

System from insulated neutral

Vіdminnіst polyagaє in that, scho neutral provіd, scho carry, vikonanim isolating. The system includes darts SIP-1a, 2a and AMKA-T.

The stagnation of insulated neutral fluid is necessary for the prevention of corrosion near the coastal sea areas and chemically active environments. Іstotnim nedolіk system є vsoke vantazhennja on іzolyatsіyu neutral provіdnik. When the anchors are stuck, shed them to change, so that the zahisny ball does not collapse. At the reshti vipadkіv zastosovuєtsya goal neutral.

Provid SIP: characteristics of a self-supporting system

The self-supporting system does not avenge a neutral dart, on which the entire bundle is trimmed. Before it, enter 1 to 4 of the same insulated conductors. A single wire SIP-3 and twisted into a bundle SIP-4 and 5 are brought up to it.

Global parameters SIP

1. Operating temperature - range -60...+50 0 С.
2. Vikonannya for the peaceful and cold climate.
3. Possibility of installation at temperatures up to -100C.
4. The term of operation with a guarantee is 5 years, and applications - up to 40 years.

The span of the SIP wires is located between 16-150 mm2. For the introduction of the rozrakhunkiv into the house for the allowable tension, it is not necessary, the shards of the minimum size should be removed from the reserve. On the marking, the first number determines the type of drotu, and then it indicates the number of lived that pereriz, for example, the wire SIP-2x16.

Provid skhilny to mechanical advances. For rozrahunka on mіtsnіst nebhіdno vаgu drota CIP, vіd dії dії vynikає vertikalno navantazhennya. In addition, on the new ice is the strength of the wind, which is direct to the horizontal. Vagu drota, be it a brand, can be assigned to the tables.

Mounting

The laying of wires does not depend on the important possession of those special skills, if you want to be carried out carefully, so as to avoid poor insulation.

On the stovpah, fastenings are installed for anchors and gurkit, after which a rope-leader is started. Until the new, drіt creak and stretch, winding from the coils. On the rollers, sound the application of a cold plastic ball. Conductor is not guilty of contact with the ground and third-party objects. Create a tightness, controlling its value for additional fittings. Then we will see through the rollers, fasten at the stretch and roll up the stitching or the introduction of the lines with the appropriate ones and with the help of hermetic seals.

Particularly insulated wires - the creation of an overhead electrical contact for additional spikes that are pierced. The stink of slacking off on the tack. Possibility of connection under voltage: this design allows you to carry out the work safely.

Anchor fastenings are fixed on the supports, and when mounting the inlet, a wall bracket is fixed on the other end. As soon as the booth is large, an intermediate support is installed with a supportive zatiskach.

De zastosovuyutsya droti SIP

The laying of such wires will not require large wires. The presence of insulation creates protection from a short circuit when it is closed between wires. You can creep up to the walls without insulators. When mounting, less supports are required.

Zdebіlhogo provіd priznacheniya for power lines or lighting at pressure up to 1 kV. Conducting zastosovuєtsya at budіvnitstvі pіtryanyh lep and vіdgaluzhen zhytlovі boudinka and pobutovі sporudi.

Visnovok

Not long ago, few people knew about such a virib, as a provіd CIP. What did they understand that, if they beat the yogo numerically for the bagatma by show-offs over the old line on the insulators. Laying is carried out in a short term, without folding that important possession, but the tools are needed in a complete set, and the qualifications of the electrician of the obov'yazkovo may be high. Polyethylene insulation will require a lot of maintenance.
