XLPE Insulatioin 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 mechanical performance, it also features characteristics of simple structure, light weight, no drop limit, weather resistant, chemical corrosion resistant and long working 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 
2. Max. Temperature of cable conductor shall be no more than 250º C during short circuit (the longest lasting time shall be no more than 5 seconds) 
3. Ambient temperature for installation is no less than 0º C 
4. Min bending radium of cable: 
For three cores cable, no less than 15 times of outer diameter 
For single core cable, no less than 20 times of outer diameter 
5. A. C. Rated voltage U0/U of cable is 0.6/1kV~26/35kV 
U0: Phase voltage. Rated A. C. Voltage of conductor to earth or between metallic shielding 
U: Wire voltage. Rated A. C. Voltage between conductors 
Um: Max endurable value of "Max system voltage" for cable

 

Model Description   Application
