Low-voltage XLPE insulated power cable is manufactured according to GB 12706-91 or IEC60502.
Standards:Low-voltage XLPE insulated power cableis manufactured according to GB 12706-91 or IEC60502.it is suitable to be installed in the power line with rated voltage of 0.6-1KV ofr tansmitting electricity.
Operation Characteristic:
Maximum rated temperature: The max operating temperature of cores shall not exceed 90°C.When the cable is used for long petiod, the temperature of core shall bot exceed 250°C at short ciruit for seconds.
The requirement of installment:The installation of cables is not limited by the difference of level along the route.The ambient temperature should not be below 0°C during installation.the minimum bending radius shall not be less than 10 times of the cable overall diameter when laying.
