Conductor

Copper, single-wire or multi-wire core, of circular or sector-shaped form, of the 1 or 2 class according to GOST 22483 with the cross-section from 1.5 to 1000mm².

For cable of type VVG-Png(A)-FRKhL single-wire core to 16 mm² of circular form of the 1 class according to GOST 22483

Thermal barrier

The lapping with two fiber glass mica tapes.

Insulation

PVC-compound of low flammability (color coded conductor)

Core arrangement and twisting

Insulated conductors of 2, 3, 4, 5 and 6 core cables are twisted.

For cables of types VVG-Png(A)-FRKhL insulated conductors of 2, 3 core cables are arranged in parallel in one flat .

Inner sheath

PVC-compound of low flammability is made of filling of outer space between conductors.

Screen

For cables of type VVGЕng(A)-FRKhL with copper tapes or copper wires and a spirally imposed copper tape.

Cable armoring

It is laid helically with two steel, galvanized tapes for cables of type VVGng(A)-FRKhL.

Over sheath

Nominal voltage, kV 0,66 or 1 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 0.66 and 1kV and frequency 50 Hz or at direct voltage 1 and 1.5 kV with the possibility of installation without preheat at temperatures up to minus 30⁰C.

The cables are used at group installation of cable lines in cable structures, outdoor (open-air) electric units (cable racks and galleries). Fire resisting cables in modification “flame retardant – Fire-Resistant Cold-Resistant” keep working in terms of exposure by the flame for 180 minutes.

For manufacturing of the cables the materials which provide resistance of the cables to the impact of ambient low temperature to minus 60⁰C are used.

The class of fire hazard of the cables according to GOST П1б.1.2.5.4.
