AERIAL CABLE WITH RATED VOLTAGE 10Kv OR 35Kv

1、Type and Applications

　　It is manufactured in accordance with GB 14049-93, “Aerial cable with rated voltage 10kV or 35kV”.

3. Features

　　Rated voltage U(Um) is 10(12) kilovolts or 35(42)kilovolts. It applies to the system of the duration of single phase ear thing fault normally less than 1 minutes each time or the system of maximum duration less than 8 hours each time, but the total duration not more than 125 hour.

　　Ambient temperature should be not lower than -20℃ when cable is installed.

　　Maximum temperature is 250℃ when cable is shorted for less than 5 seconds for XLPE insulated cable.

　　For cable with weighted wire construction, maximum rated temperature of conductor is 90℃ for XLPE insulated cable.

　　Minimum bending radius is as follows when cable is installed:

　　for single-core cable- 20(D+d), unit: millimeter

　　for multi- core cable- 15(D+d), unit: millimeter

Note: D denotes the overall diameter of cable, while d means the diameter of conductor, unit: millimeter

Note: 1. K denotes weighted stranding wire. You can select the corresponding cross-section in the 　　　above table as practical engineering needs. In the above cable construction it does not 　　　comprise weighted robe when the gap of tower poleis so large that it is necessary to add a 　　　weighted robe.

　　　 　　　　　　　　　 2. (A) means steel weighted stranding wire, while(B) means alluminium alloyed weighted 　　　stranding wire.
