First, the scope of application
Applicable to copper core, aluminum core cross-linked polyethylene or high-density polyethylene insulated aerial cable for overhead power lines with AC rated voltage U of 10 (12) KV and 35 (42) KV.
Second, the use of characteristics
1. Long-term allowable operating temperature of cable conductors (with load-bearing cable); cross-linked polyethylene insulation 90 ° C; high-density polyethylene insulation 75 ° C.
2. When short circuit (maximum duration is less than 5 seconds), the maximum temperature of the cable should not exceed; cross-linked polyethylene insulation is 250 °C; high-density polyethylene insulation is 150 °C.
3. The cable laying temperature should not be lower than -20 °C.
4. The allowable bending radius of the cable is not less than the diameter of the cylinder when the cable is bent.
