PVPNG (A) -HF, APVPNG (A) -HF
Description Construction
Applying area and purpose
Cables are designed for transmission and distribution of electrical energy in stationary installations for a rated alternating voltage of 6-35 kV with a nominal frequency of 50 Hz for networks with a grounded and insulated neutral;
- in rooms, tunnels, canals, mines, dry soil and in the open air under a canopy
- in bundles
- at facilities where requirements for reduced smoke and gas emissions are imposed (nuclear power plants, metro, large industrial facilities, high-rise buildings, etc.)
