10KV overhead insulated cable implements GB/T14049-2008 "rated voltage 10KV overhead insulated cable" standard and GB/T1179- -2008 "round wire concentric wire overhead conductor".
Product main performance
1, use characteristics
(1) Rated voltage 0.6/1KV, I0KV
(2) Long-term allowable working temperature of cable conductor: PVC insulation should not exceed 70 °C, and XLPE insulation should not exceed 90 °C.
(3). The maximum temperature of the cable during short circuit (maximum duration not exceeding 5S): 160*C for PVC insulation: 250°C for XLPE insulation.
(4) The laying temperature of the cable should not be lower than -20*C. Below this temperature, the cable should be preheated.
(5) Allowable bending radius of the cable.
Cable outer diameter (D) < 25mm, should not be small 4D: steel core reinforcement should be no less than 6D. The outer diameter of the cable (D) ≥ 25mm. Should be not less than 6D: The steel core reinforcement type should be no less than 10D.
The single-core cable should be no less than 20D; the steel core reinforcement type should be no less than 25D. The multi-core cable should be no less than 15D; the steel core reinforcement type should be no less than 20D. [Note: The above D is the cable outer diameter. ]
