High-voltage armored power cable three cores
1 . Product features and uses:
The cross-linked polyethylene insulated power cable has the characteristics of high mechanical strength, strong environmental stress resistance, excellent electrical performance, and strong current resistance.
Chemical corrosion. In addition, the lightweight and simple product is easy to use. This product is suitable for transmission and distribution systems with a rated voltage of 0.6/1kv.
It has the main characteristics of fire-resistant cables. The cables are not easy to catch fire or continue to burn within a certain range. It is suitable for power stations, subways, tunnels, high-rise buildings, and large-scale
Dense distributed cables in industrial and mining enterprises, oil fields, coal mines and other places.
