Aluminum conductor PVC insulated aerial cables

• Product standard
   

The product is manufactured according to the standards of GB12527-90 “Aerial insulated cables of rated voltages up to and including 1KV” and IEC60502 “Extruded solid dielectric power cables for rated voltage from 1KV to 30KV” .

• Operating characteristics

1. Rated voltage U0/U: 0.6/1kv

2. Max. permissible continuous temperature:
   PVC,PE insulated aerial cables:70℃
   XLPE insulated aerial cables:90℃

3. Max. short-circuit temperature of the conductor shall not exceed:
   PVC insulated aerial cables:160℃;
   PE  insulated aerial cables:130℃;
   XLPE insulated aerial cables:250℃.

4. The installation ambient temperature should not below -20℃.

5. The bending radius of cables are recommend as follows:
   When the diameter of cables less than 25mm: not less than 4 times
   The diameter of cables;
   When the diameter of cables not less than 25mm: not less than 6 times the diameter of cables.

6. When the cables use in alternating current system, rated voltage of cables should be at least equal the rated voltage of the system; When the cables use in direct current system, rated voltage should be not greater than 1.5 times of the rated voltage of the cables.
