4 Cores 132kV XLPE High Voltage Power Cables For Construction
1. Application :
Used for indoor & outdoor laying,The Cable can bear a certain laying traction,but can't bear the mechanical force from outide.Single core cable can't be allowed to lay in the magnetic pipe . The Cable is used for fixed laying in the rated voltage (U0/U)0.6/1KV,3.6/6KV & below for power transmission.
2. Product implementation standard:
GB/T12706-2002 Rated Voltage 1KV(uM=1.2KV) to 35KV(uM=40.5Kv) insulation electrical power & auxilary IEC60502-1997 Rated voltage 1-30kV Insulation electrical power cable & auxiliaries.
3. Operational performances:
(1) Working temperature:
The Max. conductor working temperature: 70℃ Centigrade Conductor short circuit temperature : highest temperature not more than 160℃ , the longest time not more than 5 seconds.
The min.bending radius of cable installation :
