Applicazioni:
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, posa interna è esterna, pipelines, tunnel, mines, fusti, sepultura diretta in terra è sottu à l'acqua, etc., and are able to withstand considerable pressure and mechanical forces, forza di trazione assiale.
