Operation Characteristics

During the normal operation, the max permissible continuous operating temperature of conductor should not exceed 90°C
Conductor temperature during short-circuit( 5 s maximum duration) should not exceed 250°C
The min permissible bending radius during the cable laying is normally 25 times of the cable’s OD.
The installation is not limited to the horizontal dropping varience.
Pre-heated is needed when the ambient temperature is below 0°C during installation

Application of EHV Power Cable

EHV XLPE Power cable is suitable for transmission and distribution systems in the power station.
