Background In modern industrial production, many environments place stringent demands on the high temperature resistance of the cable. When the traditional high-temperature cable works for a long time in a high-temperature environment, heat is generated due to the resistor in the process of transmitting current, and the heat is difficult to quickly dissipate.

For example, in a steel smelting workshop, the high-temperature environment often causes frequent faults of the traditional cable, and the continuity and stability of production are seriously affected. Therefore, developing a high-temperature cable capable of rapidly dissipating heat becomes a key for solving the difficult problem of cable use in the current high-temperature operation environment.
