Problems solved by technology

[0004] First, in order to achieve the required heating value, a large number of carbon fiber heating wires need to be twisted, the resistance is reduced, the current is increased, and the actual heating power is increased, that is, the power consumption is large;
[0005] Second, the heat resistance of the outer sheath of the existing carbon fiber cable is low, which cannot meet the requirements of some high-temperature application environments
