Product Description

Product Description Power Cable *6/*5kv cu/xlpe/pvc 1***0mm Executive Standard: It is manufacture under GB/T*********2 standard(The same as IEC****2). Application: It is used to transmit and distribute power in power transmission and distribution system of *5kV 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: *6/*5kV, *1/*5kV, *2/*0 kV (*4 kV), 8.7/*0kV, 8.7/*5kV, 6/6kV, 6/*0kV 2. No. Of core: Single-core, Three-core 3. The highest allowed operating temperature of conductor for long-term working is *0oC. In short-circuit (Max. Long-term is no more than 5 seconds). The highest temperature for conductor is no more than **0oC. 4. D. C. Resistance of the conductor complies with the stipulations of GB/T********7. 5. The environment temperature should be no lower than 0oC when lay. Otherwise it should be preheated. 6. The cable is laid without horizontal drop limit. 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~*8kV: 3.5Uo/5min without puncture. For cable with Uo of *1kV and *6 kV: 2.5Uo/*0min without puncture. 8. Partial Discharge Test: The discharge volume should be no more than *0pC under 1.*3Uo for the cable.
