The maximum rated temperature
XLPE insulated,the maximum operating temperature of conductor shall exceed 90℃when the cable is used for long not period. The temperature of conductor shall not exceed 250℃ at short circuit for 5 seconds.
PVC insulated,the maximum operating temperature of conductor shall exceed 90℃ or 70 ℃ when the cable is used for long not period. PVC insulated the temperature of conductor shall not exceed 160℃ at short circuit for 5 seconds.
Installation requirement
The installation of cable is not limited by the difference of elevation along the route. The ambient temperature should not be below 0℃ during installation. The permissible bending radius for cable shall be complied with the following regulations:
For single-core: R>20(D+d) +/-5%
For multi-core: R>15(D+d) +/-5%
Where:R—bending radius (mm) , D—overall diameter of the cable (mm) , d—diameter of conductor (mm).
Single core cable of using in AC circuit shall be without armour or with steel wire armour and shall not be laid in magnetic ducs.
