 Medium Voltage Stranded Copper Conductor 8.7/15 KV Steel Wire Armored Power Cable According to IEC 60502-2

 

 

Application:
It is used to transmit and distribute power in power transmission and distribution system of 35kV or lower. It is generally applied to the fields including power, construction, mines, metallurgy, petrochemical industry and communication in complete replace of oil immersed paper insulated power cable and in partial replace of PVC insulated power cable.

 

 

Using features:
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 degree.
4. D. C. Resistance of the conductor complies with the stipulations of international standar.
5. The environment temperature should be no lower than zero degree when lay. Otherwise it should be preheated.
6. The cable is laid without horizontal drop limit. The Min. Bending radius of cables 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.
