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.
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.
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.
