ВБШвнг(А)-ХЛ (VBShVng(A)–KhL)- Russian analogue of NYBY Cold Resistance Flame Retardant

SCOPE AND PURPOSE

The cables are designed for transmission and distribution of electric energy in stationary electric installations on alternating voltage 0,66 and 1 kV and frequency 50 Hz or direct voltage 1 and 1.5 kV correspondingly with the possibility of installation without preheat at temperature up to -30^o C.

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

The armored cables are used in case of danger of mechanical damage in process of operation, if the cable is not subjected to significant tensile forces.

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

The class of fire hazard of the cables according to GOST 31565 of cables of modification «ng (À)–KhL» -П1б.8.2.5.4.
