Conductor

Copper or aluminum core of the 1 or 2 class according to GOST 22483.

Insulation

PVC-compound (color coded conductor).

Core arrangement

Insulated conductors of multi-wire conductors twisted in cable core.

Inner sheath

PVC-compound, it is made by extrusion with filling of exterior gaps between insulated cores for no armored neither screened cables.

Cable armoring

In cables of types VKShv-KhL, AVKShv-KhL cable armor is laid with steel, galvanized wires.

In cables of types VBaShv-KhL, AVBaShv-KhL cable armor is laid with two aluminum tapes.

In cables of types VKaShv-KhL and AVKaShvKhL cable armor is laid with aluminum wires.

Cable sheath or jacket

PVC-compound

The cables are designed for transmission and distribution of electric energy in stationary installations on a nominal alternating voltage 0,66 and 1kV, nominal frequency 50 Hz

The cables are used for single installation in cable constructions, open-air electrical installations (cable overpasses, arcades).

The cables armored with steel, galvanized wires or wires of aluminum or aluminum alloy are designed for laying on the route, where the tensile forces during exploration are possible, including for installation in seismically active areas, in conditions of permafrost and areas, subjected to offset soil, in bulk and dry soils.

While manufacturing the cables the materials, which allow the cables to be resistant to low temperatures up to – 60⁰C (degrees below zero) are used.

The class of fire hazard of the cables is according to GOST 31565 01.8.2.5.4.
