Iarrtasan:
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, suidheachadh a-staigh agus a-muigh, pìoban, tunailean, mines, shafts, direct burial in the soil and underwater, etc., and are able to withstand considerable pressure and mechanical forces, axial tensile force.
