1. The long-term allowable working temperature of the cable conductor does not exceed 70 °C;
2, when short circuit (the longest duration does not exceed 5 seconds), the maximum temperature of the cable conductor does not exceed 160 ° C;
3. The ambient temperature when laying the cable should not be lower than 0 °C.

Second, the use of characteristics

1. The maximum rated temperature of the cable conductor is 90 °C, and the short-circuit time (maximum duration does not exceed 5S), the maximum temperature of the cable conductor does not exceed 250 °C.
2. The ambient temperature when laying the cable should not be lower than 0 °C
3. Allow bending radius when laying: single core cable is not less than 15 times of cable outer diameter; multi-core cable is not less than 10 times outer diameter of cable
