Specifications

1.2.5mm pvc insulated power cable with IEC standard
2.not easy to burn
3.installation in density places
4.high quality

1.Operating Features:

Max permissible operation temperature of conductor is 70 degree,

When short circuit not more than 165 degree.

Ambient temperature of installation is not lower  than 0 degree

 

2:standard

 IEC 60502,    GB 12706-2008

 

3:Application:

The cable can not only operation in nominal condition, but also can operationin fire during a certain time. These cables are suitable for power station, subway, high building and other high human density places where having fire proof and free fight requirements.
