Characteristics And Applications Of Power Cables

Main features:

1. The long-term allowable working temperature of cable conductor shall not exceed 70 ℃. In case of short circuit (preferably lasting no more than 5 seconds), the maximum temperature of the cable conductor shall not exceed 160 degrees.

2. The ambient temperature during cable laying shall not be lower than 0 ° C. if it is lower than 0 ° C, it shall be preheated first. The minimum bending radius shall not be less than the outer diameter of the cable. The single core cable shall be 20 times without armor and 15 times with armor. The three core cable is 15 times armored and 12 times armored.

3. The DC cathode of conductor shall comply with the provisions of GB / t3956.

4. Power frequency withstand voltage test: 3.5kv/5min without breakdown.

Main purpose:

This product is suitable for power transmission and distribution in lines with AC rated voltage of 0.6/1kv. Flame retardant power cables are suitable for occasions requiring flame retardant.

Fire resistant power cables are suitable for high-rise buildings, large shopping malls and other densely populated areas.
