Power cable APvV, PvV
Power cables of the AПвВ and ПвВ brands are designed for the transmission and distribution of electrical energy in stationary installations with a nominal alternating voltage of 6, 10, 15, 20, and 35 kV at a frequency of 50 Hz, in networks with grounded and isolated neutrals.
Structural features:
- Conductor: round, multi-wire compacted, made of aluminum (AПвВ) or copper (ПвВ) with a cross-section ranging from 35 to 1000 sq.mm.
- Insulation: made of peroxide-crosslinked polyethylene (XLPE).
- Insulation screen: a semiconducting layer applied over the insulation.
- Copper wire screen: with a cross-section of at least 16 sq.mm for cables with conductor cross-sections of 35–120 sq.mm; at least 25 sq.mm for cross-sections of 150–300 sq.mm; at least 35 sq.mm for cross-sections above 300 sq.mm.
- Sheath: for cables with the "П" index — made of polyethylene; for "В" — made of polyvinyl chloride plasticate (PVC).
Application:
The cables are intended for laying in the ground (in trenches) regardless of the soil's corrosive activity, provided they are protected from mechanical damage.
Fire hazard class:
According to GOST 31565-2012, the cables belong to class 02.8.2.5.4.
