VDE 0276 Standard MV Single Core Cables
Conductor: Stranded round copper or aluminum conductor
Conductor shielding: The conductor shielding consists of a non-metallic extruded layer of semiconductor composite layers tightly wrapped around an insulating layer to exclude internal gaps.
Insulation: Extruded XLPE-2XI1 type compound according to DIN VDE 0207 part 22 and HD 620.1.

Applications:
Power single-core cables with voltage ranging from 3.8/6.6KV to 19/33KV and frequency of 50Hz are mainly used in power supply stations, indoor and outdoor laying, pipelines, tunnels, mines, shafts, direct burial in the soil and underwater, etc. They are able to withstand considerable pressure and mechanical forces, axial tensile force.
