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