[0002] The manufacturing of wires and cables is completely different from the production method of most electromechanical products. Electromechanical products usually adopt the method of assembling parts into components, and multiple components are assembled into a single product. The products are measured in units or pieces. Wires and cables are measured in length. All wires and cables start with conductor processing. Insulation, shielding, cabling, sheath, etc. are added layer by layer on the outside of the conductor to make wire and cable products. The more complex the product structure, the more superimposed layers there are.
[0003] The outer layers of some existing cables have poor high temperature resistance. When exposed to high temperatures, the protective layer of the cable will easily soften and melt, thereby weakening the protection of the metal cable core, which may further damage the metal cable core.
