Product description

Implementation of standards:GB/T12527-2008
Uses: This product is suitable for AC rated voltage 1KV and below overhead power line transmission。
Characteristics
The cable conductor long-term allowable working temperature does not exceed:
Polyvinyl chloride, polyethylene insulated aerial cable:70℃;
XLPE insulated overhead cables:90℃。
Short circuit (the longest duration of not more than 5 seconds) cable conductor highest temperature should not exceed:
PVC insulated aerial cables:160℃
PE insulated aerial cable:130℃
XLPE insulated overhead cables:250℃
Cable laying ambient temperature should be not lower than -20 ° C
Allowed bend radius of the cable:
Cable diameter less than 25mm, should be no less than 4 times the diameter of the cable.
Cable diameter equal to or greater than 25mm, should be no less than six times the cable diameter.
When the cable is used in the AC system, the rated voltage of the cable should be at least equal to the rated voltage of the system; When the cable used in the DC system, the rated voltage of the system should not be greater than 1.5 times the cable rated voltage。
