1. Rated voltage: Uo/U: 26/35kV, 21/35kV, 12/20 kV (24 kV), 8.7/10kV, 8.7/15kV, 6/6kV, 6/10kV.




2. No. of core: Single-core, Three-core.




3. The highest allowed operating temperature of conductor for long-term working is 90oC. In short-circuit (Max. Long-term is no more than 5 seconds). The highest temperature for conductor is no more than 250.




4. D.C Resistance of the conductor complies with the stipulations of GB/T3956-1997.




5. The environment temperature should be no lower than 0 when lay. Otherwise it should be preheated.




6. The cable is laid without horizontal drop limit. The Min. Bending radius of three-core cable should be no smaller than 12 times of cable outer diameter.




7. Working Frequency Voltage Test:.




For cable with Uo of 3.6kV or lower: 2.5Uo+2kV/5min without puncture.

For cable with Uo of 3.6kv~18kV: 3.5Uo/5min without puncture.

For cable with Uo of 21kV and 26 kV: 2.5Uo/30min without puncture.




8. Partial Discharge Test: The discharge volume should be no more than 10pC under 1.73Uo for the cable.
