КВВГЭнг(А)-LS (KVVGEng(A)-LS) - Russian analogue of NY(St)Y Flame Retardant Low Smoke

SCOPE AND PURPOSE

The cables are designed for transmission and distribution of nominal electric power and electric signals at the stationary installation on the nominal alternating voltage 660 V of frequency up to 100 Hz or correspondingly on direct voltage 1000V .

The cables are designed for group installation of cable lines in cable structures and premises of indoor (closed) electric units in case of absence of danger of mechanic damage in process of operation.

The cables are recommended for fixed connection to electrical devices and equipment, to assemblies of clamps of electrical switch gear primarily for fixed connection to electric devices, appliances, assembly clamps of electrical switchgear at nuclear power plants, in residential and public buildings and other objects, which are increased requirements for fire safety. The cables are made for objects of nuclear energy use in NPP systems of classes 3 and 4 according to the classification ОПБ-88/97 (ПНАЭ Г-01-011).

The class of fire hazard of the cables according to GOST 31565 П1б.8.2.2.2.
