Power cable VVG, AVVG
Power cables of the VVG and AVVG brands are designed for the transmission and distribution of electrical energy in stationary installations with a nominal alternating voltage of 0.66, 1, 3, and 6 kV at a frequency of 50 Hz.
Structural features:
- Conductor: round or sector-shaped, single-wire or multi-wire compacted, made of copper (VVG) or aluminum (AVVG).
- Insulation: made of polyvinyl chloride plasticate (PVC) or cross-linked polyethylene (XLPE).
- Twisting: insulated conductors are twisted together.
- Inner filling: for cables without armor or screen — made of unvulcanized rubber compound or PVC plasticate; for cables with armor or screen — made of PVC plasticate or applied by wrapping or longitudinally with PVC plasticate tapes.
- Screen: made of copper wires and a binding copper tape; it is permissible to manufacture the screen from two copper tapes or copper foil.
- Separator layer: for cables with a screen — made of crepe or cable paper, or rubberized fabric, or polypropylene tape.
- Belt insulation: for cables with a screen and armor — made of PVC plasticate.
- Armor: for cables of the (A)VBBShv, (A)VBShv, (A)PvBShv types — made of two galvanized steel tapes; for cables of the (A)VEBCbShv, (A)VKShv, (A)VVCbShv types — made of galvanized steel wires; for cables of the (A)VEVCbShv, (A)VEVCaShv, (A)VKaShv types — made of aluminum wires or wires made of aluminum alloy.
- Sheath: made of PVC plasticate.
Application:
The cables are intended for laying single cable lines in cable structures and premises. When laying in groups, the use of fire protection means is mandatory.
