XLPE Insulation Power Cable

General 
The cable is used for power transmission and distribution on power line of A.C. 50Hz, rated voltage 35KV or lower. Besides great electrical and mechanicalperformance, it also features characteristics of simple structure, lightweight, no drop limit, weather resistant, chemical corrosion resistant and longworking duration under high temperature. 

Executive standard 
GB/T12706.1-2002~GB/T12706.3-2002 or IEC60502-1997 

Working Conditions 
1. Max. Working temperature for conductor is 90º C
