INSULATION, FILLER AND SHEATH
VVGng(A)-FRLS
Insulation and sheath of polyvinyl chloride compound with low fire danger and reduced smoke and gas emission. A thermal barrier of two mica-containing tapes is placed on top of the conductor
VVGng(A)-FRLSLTx
Insulation and sheath of polyvinyl chloride compound with low fire danger and low toxicity of combustion products. A thermal barrier of two mica-containing tapes is placed on top of the conductor
APPLICATIONS
The cables are designed for transmission and distribution of electric power in stationary electrical installations with a rated alternating voltage of 0.66 and 1 kV of a rated frequency of 50Hz.
For cable power lines for power supply to NPP security system equipment, electrical wiring for fire safety system circuits (fire alarm circuits, power supply to fire extinguishing pump, lighting of emergency exits and escape routes, smoke exhaust systems and supply ventilation, emergency elevators). For electrical wiring in surgical units of hospitals, emergency power supply circuits and power supply to equipment (current collectors) operating in case of fire.
