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.
STRUCTURE
Conductor
Copper, single-wire, of the 1 class according to GOST 22483, with the cross-section from 0.75 to 6 mm2.
Insulation
PVC-compound of low flammability.
Core arrangement
From 4 to 61 insulated conductors.
The insulated conductors of the cables are twisted.
Control cables have distinctive markings of insulated conductors (digital or color).
Separating layer
PVC-compound of low flammability.
Screen
For cables of types NY(St)Y Flame Retardant Low Smoke - foiled alumoflex with the contact conductor with a copper, galvanized wire.
Over sheath
PVC-compound of low flammability.
