Aerial Insulated Cables Within Rated Voltage Up To Including 0.6/1KV
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°C
XLPE insulated aerial cables:90°C
3. Max. short-circuit temperature of the conductor shall not exceed:
PVC insulated aerial cables:160°C;
PE insulated aerial cables:130°C;
XLPE insulated aerial cables:250°C.
4. The installation ambient temperature should not below -20°C.
5. The bending radiuses of cables are recommended 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.
