 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.
