The Use of Overhead Cable Features
First, the implementation of production standards
1.1kV overhead insulated cable: GB12527-90 is equal to the International Electrotechnical Commission IEC60502, IEC227;
2.10kV overhead insulated cable:GB14049-93 is equal to the International Electrotechnical Commission IEC60502.
2.Long-term allowable working temperature of the cable: PVC insulation is 70 ℃, XLPE insulation is 90 ℃;
3.Short circuit (the longest time does not exceed 5 seconds), the maximum temperature of overhead cable: PVC insulation is 160 ℃, high density PE insulation 150 ℃, XLPE insulation 250 ℃;
4.Cable laying ambient temperature of not less than -20 ℃;
5.The permissible bending radius of the cable:
(1)Rated voltage below 1kV: the cable outside diameter (d) less than 25mm, should not be less than 4D, the cable outer diameter (d) is 25mm and above, should not be less than 6d;
(2)Rated voltage 10KV cable should not be less than 20 (D + d). Where: the actual outside diameter of the D-cable, d-the actual outside diameter of the cable conductor.
