VBVng(A), AVBVng(A), according to specifications 16.K71-359-2005
specifications 16.K71-359-2005


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


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

Inner sheath

It is made by extrusion with PVC-compound of low flammability 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 non hygroscopic fiber or polymer materials with the lapping of fastening tape, on the top of which the extrusion inner sheath is laid. It is allowed to wrap the cable core with the layer of tapes of polymer material, compatible with the materials of insulation and over sheath.


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


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.


Of PVC-compound of low flammability.

Cable armoring

It is lapped helically with two steel, galvanized tapes. It is possible to overlap or wrap longitudinally with PET or polypropylene tape.

Over sheath

Of PVC-compound of low flammability.

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.

They can be laid in dry soils (sand, sandy-clay and normal soil with a moisture content of 14%). The cables can be laid in the explosive areas of classes B-1б, В-1г, В-II, B-IIa.

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
