10 kV Aerial Insulated Cables Using Feature
Maximum long-term allowable operating temperature of the cable conductor (with load bearing structure cable)
1. Cross-linked polyethylene insulation 90℃;
2. High-density polyethylene insulation 75℃. In case of a short circuit (maximum duration not exceeding 5 seconds) the maximum temperature of the cable should not exceed:
(1). Cross-linked polyethylene insulation 250℃;
(2). High-density polyethylene insulation 150℃. The laying temperature of the cable shall not be lower than -20℃; the allowable bending radius of the cable shall not be less than the diameter of the cylinder used in the cable bending test.
