Feidhmithe:
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, leagan laistigh agus lasmuigh, píblínte, tolláin, mianaigh, seaftaí, adhlacadh díreach san ithir agus faoi uisce, srl., and are able to withstand considerable pressure and mechanical forces, fórsa teanntachta aiseach.
