 Application
1,Long term working temperature for the cable with PVC insulated is 70ºC;
Long term working temperature for the cable with XLPE insulated is 90ºC
2,Short circuit temperature
For PVC insulated cable ,the highest conductor temperature is not more than160ºC.(lasting time not over 5 seconds).
For XLPE insulated cable ,the highest conductor temperature is not more than250ºC.(Lasting time is not over 5 seconds).
3,Laying temperature not less than 0ºC and the drop height is out of consideration.
4,The cable with chemical stability, anti- acid, anti-alkali, anti-oil, anti-organic solvent, not easy to be burning.
5,Easy for installation, easy bending and light.



Operating characteristics
- Rated power-frepuency voltage U0/U: 3.6/6kv~26/35kv.
- Max.admissible operating temperature of the conductor:90ºC.
- Max. short-circurt temperature of conductor shall not exceed 2500C. (5s maximum duration)
- The ambient temperature under installation should not below 00C.
- The bending radius of a single-core cable should not less than 20 times of the cable diameter. 
The bending radius of a multi-core cable should not less than 15 times of the cable diameter.
