AВБВнг(А)-LS (AVBVng(A)-LS)

SCOPE AND PURPOSE

The cables are designed for transmission and distribution of electric power at the stationary installation on the nominal alternating voltage 6kV of frequency 50 Hz for networks with the earthed and insulated neutral.

The climate modification УХЛ, categories of location 1 and 5 according to GOST 15150, including installation in the ground.

The class of fire hazard of the cables according to GOST 31565 П1б.8.2.2.2.

STRUCTURE

Conductor

Aluminum, single-wire or multi-wire, of circular or sector-shaped form, of the 1 or 2 class according to GOST 22483.

Insulation

Is made of PVC-compound of low fire hazard (color coded conductor).

Core arrangement

Insulated conductors of multi-core cables are twisted in a cable core.

Inner sheath

It is made by extrusion with PVC-compound of low fire hazard or chalk-filled non-cured rubber with the filling of outer gaps between insulated conductors. It is possible to fill the outer gaps between circular insulated cores with the bundles of with the lapping of fastening tape and extrusion inner sheath. It is allowed to wrap the cable core with the tapes of polymer material.

Taping

Is made of tape or tapes of conductive paper or conductive synthetic tape, or tapes of non-woven conductive fabric.

Screen

Of copper wires and a spirally imposed copper tape. It is allowed the application of the screen with copper tapes.

Separating layer

Of polymer tape or non-woven fabric.

Bedding

Of PVC-compound of low fire hazard.

Cable armoring

Is lapped helically with two steel, galvanized tapes.

Over sheath

Of PVC-compound of low fire hazard.
