It is suitable for power grid with rated voltage 0.6/1kV or the power transmission in the power equipment.
The highest environment permissible continuous operating temperature for the conductor of the PVC Insulating Power Cable to work normally is 70℃. In case of short circuit (with duration less than 5 seconds), the highest temperature of the conductor is less than 160℃.
The ambient temperature under installation should not be below 0℃.
The recommended bending radius: for mono-core cable, not less than 20 times of the cable's actual external diameter; for multi-core cable, not less than 15 times of the cable's actual external diameter.
