Problems solved by technology

[0002] High-voltage cable is a kind of power cable, which refers to the power cable used to transmit 1kv-1000kv, and is mostly used in power transmission and distribution. The cable is a bridge between power supply equipment and electrical equipment, and plays the role of transmitting electric energy. It is widely used, so faults often occur. The cable crush caused by thermal expansion of the cable leads to breakdown. When the load of the cross-linked cable is high, the temperature of the core rises, and the cable expands
