XLPE insulated high voltage power cable is used to transmit power on the power transmission and distribution line of A.C.50Hz, rated voltage 35kV or lower, and also used for Subway,Power station,Factory and Mine.It can be installed underground, in pipe, in trench or in tunnel.
XLPE Cable not only has excellent electric character, mechanical character, heat and aging-resistant character, environmental stress-resistant character and chemical corrosion- resistant character, but simple structure, light weight, no restriction by laying drop, and high temperature allowance for long-term working as well.
XLPE insulated power cable is used to transmit power on the power tansmission and distribution of AC,rated voltage 35kv or lower.Incompatison with PVC insulation cable,It boasts not only excellent electric character,mechanical chatacter,heat and agingresistant character,environmental stress-resistant chatacter and chemical corrosionresistant chatacter,but simplw structure,light weight,no restiction by laying drop,and hight temperature allowance for long-term working as well.
