КВЭБШв-ХЛ (KVEBShv-KhL)

SCOPE AND PURPOSE

The cables are designed for transmission and distribution of electric power at the stationary installation on the nominal alternating voltage of frequency 50 Hz for main conductors 6 kV and for auxiliary conductor to 0.38 kV.

The cables are used for single installation on the horizontal and inclined workings of the mines without restriction of difference in levels, on the surface of mines, pits and for laying in the ground in case of danger of mechanic damage in process of operation, if the cable is not exposed to significant tensile force.

For manufacturing of the cables the materials which allow the cables to be resistant to effect of low temperature are used.

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

STRUCTURE

Main conductor

Copper, single-wire or multi-wire, of circular or sector-shaped form, of the 1 or 2 class according to GOST 22483, with the cross-section from 25 to 240 mm².

Auxiliary conductor

Copper, single-wire, of circular form, of the 1 class according to GOST 22483, with the cross-section from 6 to 10 mm².

Earth conductor

Copper, single-wire or multi-wire core, of circular form, of the 1 or 2 class according to GOST 22483 with the cross-section from 10 to 70mm².

For cables with the main conductors of sector-shaped form can consist of three separated conductors, meanwhile the cross-section of each conductor makes one third of the total cross-section of the earth conductor.

Insulation

For main and auxiliary conductors - PVC-compound (color coded conductor).

Screen

Is made of taping with the tapes of conductive non-woven fabric and with copper tapes.

Core arrangement

Screened conductors of 3-core cables, auxiliary conductor and earth conductor are twisted.

Inner sheath

It is made by extrusion with PVC-compound with the filling of outer gaps between conductors.

Cable armoring

It is laid helically with two steel, galvanized tapes.

Jacket

PVC-compound.
