КВЭБШв(у)нг(А)-ХЛ (KVEBShv(u)ng(A)KhL) - Russian analogue of BiTmining YHKGYFtZnen 3,6/6kB (NYSEBYv Cold Resistance Flame Retardant)
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 provide resistance of the cables to impact of ambient low temperature are used.
The class of fire hazard of the cables according to GOST 31565 П1б.126.96.36.199.
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 240mm2.
Copper, single-wire, of circular form, of the 1 class according to GOST 22483, with the cross-section from 6 to 10 mm2.
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.
For main and auxiliary conductors - PVC-compound (color coded conductor).
Is made by taping with the tape of conductive non-woven fabric and of a copper tape.
Screened conductors of 3-core cables, auxiliary conductor and earth conductor are twisted.
It is made by extrusion with PVC-compound with the filling of outer gaps between conductors
Is lapped helically with two steel, galvanized tapes.
PVC-compound of low flammability. For modification “(u)” forced protective jacket.
