Standard

The product is manufactured according to the standard of GB12527-90 <<Aerial insulatd cables of rated voltages up to and including 1kv>> and IEC60502 <<Extruded solid dielectric power cables for rated voltages from 1kv to 30kv >>

Operating characteristics

1, Rated voltage Uo/U : 0.6/1kv

2, Max. permissible continuous  temperature

PVC,PE insulated aerial cables :70

XLPE insulatd aerial cables: 90

3, Max.short-circuit temperature of the conductor shall not exceed :

  PVC insulated aerial cables :160

    PE insulated aerial cables:130

  XIPE insulated aerial calbes:250

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

5, The bending radius of cables are reeomnlend 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 voltate of cables should be at least equal the rated voltage of the system;when the cables use in direct current system, rated voltage of the system should be not greater than 1.5 times of the rated voltage of the cables.
