Aerial Insulated Cables Within Rated Voltage 10KV And 35KV
Product standard
The product is manufactured according to the standards of GB14049“Aerial insulated cables of rated voltages 10 KV and 35KV” and IEC60502“Extruded solid dielectric power cables for rated voltages from 1KV to 30KV”.
Operating characteristics
Rated voltage: 10KV, 35KV: Max. permissible continuous temperature:HDPE insulated aerial cables: 75°C; XLPE insulated aerial cables: 90°C
Max. short circuit temperature of the conductor shall not exceed:HDPE insulated aerial cables: 150°C; XLPE insulated aerial cables: 250°C
The installation ambient temperature should not below -20°CThe bending radius of cables are recommended as follows:Single cable: not less than 20 times the diameter of cables; Multi-core cables: not less than 15 times the diameter of cables.
