Use function:

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. Number of cores: single core, triple core.

3. The maximum allowable working temperature of the conductor for long-term work is 90oC. In a short-circuit state (the longest duration does not exceed 5 seconds). The maximum temperature of the conductor does not exceed 250.

4. The DC resistance of the conductor meets the requirements of GB/T3956-1997.

5. The ambient temperature should not be lower than 0 when laying. Otherwise, it should be preheated.

6. There is no horizontal drop limit when laying cables. The bending radius of the sensitive three-core cable should not be less than 12 times the outer diameter of the cable.

7. Working frequency voltage test:

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

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

For cables with Uo of 21kV and 26 kV: 2.5Uo / 30min, no puncture.

8. Partial discharge test: The discharge capacity of the cable at 1.73Uo should not exceed 10pC.
