Applikazzjonijiet:
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, tqegħid fuq ġewwa u barra, pipelines, mini, minjieri, xaftijiet, dfin dirett fil-ħamrija u taħt l-ilma, eċċ., and are able to withstand considerable pressure and mechanical forces, forza tat-tensjoni axjali.
