ВБШвг-ХЛ (VBShvg-KhL) – Russian analogue of NY(F)BY Cold Resistance
SCOPE AND PURPOSE
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 or direct voltage 1 and 1.5 kV respectively.
The cables are used for single installation of cable lines in cable constructions, open-air electrical installations (cable overpasses, arcades).
Cable VBShVg-KhL is also used for laying in the ground.
While manufacturing the cables we use the materials, which allow the cables to be resistant to low temperatures up to – 600C (degrees below zero) and water blocking materials as well, which allow the cables to be resistant to the longitudinal penetration of moisture and their use in conditions of high humidity.
The class of fire hazard of the cables is according to GOST 31565 01.8.2.5.4.
Copper core, single-wire or multiwire, circular or sector-shaped form of the 1 or 2 class according to GOST 22483.
PVC- compound (color coded conductor).
Insulated conductors of 2, 3, 4, 5 or 6 core cables twisted with water blocking materials.
It is made by extrusion with filling of exterior gaps between insulated cores or for not armored cables with copper sector-shaped conductors with taping with PVC tapes with the filling of exterior gaps between insulated cores, insulating cords (bundles).
Two steel galvanized tapes are superimposed spirally.
Water blocking tapes are superimposed by winding.
