Characteristics of XLPE insulated PVC sheathed power cables


1) The maximum rated temperature of the cable conductor is 90℃.

2) During short circuit (the longest duration is not more than 5s), the maximum temperature of the cable conductor does not exceed 250℃.

3) The allowable bending radius of single-core cable is 20(d+D)±5%.

    The allowable bending radius of multi-core cables is 15(d+D)±5%.

    D = Actual outer diameter of the cable sample (mm)

    d=actual outer diameter of conductor (mm)

4) The cable laying temperature should not be lower than 0℃.
