КВБбШв (KVBbShv) - Russian analogue of NYBY

SCOPE AND PURPOSE

The cables are designed for fixed connection to electrical devices and equipment to assemblies of clamps of electrical switch gear with the nominal alternating voltage up to 660V of frequency up to 100 Hz or direct voltage up to 1000V.

The cables of type KVBbShv are used for installation in the premises, conduits, tunnels, in conditions of aggressive environment and in areas exposed to stray currents, if the cable was not subjected to significant tensile force.

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