JKLGYJ(1KV）1KV钢芯铝绞线芯绞聚乙烯绝缘架空电缆
This product is suitable for overhead power distribution lines with a rated voltage of 1kV and below. It has the characteristics of safe use, weather resistance, wear resistance, high mechanical strength, and low line loss. It is widely used in urban and forest area power grid renovation, and can greatly improve the safety and reliability of the power grid.
1. The long-term allowable working temperature of cable conductors shall not exceed:
PVC and polyethylene insulated overhead cables: 70 ℃; Crosslinked polyethylene insulated overhead cable: 90 ℃.
2. The ambient temperature during cable laying should not be lower than -20 ℃.
3. Allowable bending radius of cables:
When the outer diameter (D) of the cable is less than 25mm, it should not be less than 4 times the outer diameter of the cable; When the outer diameter (D) of the cable is equal to or greater than 25mm, it should not be less than 6 times the outer diameter of the cable.
4. When the cable is used in an AC system, the rated voltage of the cable should be at least equal to the rated voltage of the system; When cables are used in a DC system, the rated voltage of the system should not exceed 1.5 times the rated voltage of the cable
