[0018] The utility model has at least the following beneficial effects:

[0019] 1. In the utility model, a power and brake cable for a servo system is realized. The flexibility of the cable of the utility model is increased by arranging a cable core body formed by twisting a plurality of copper wires with small diameters, the structural strength of the cable of the utility model is increased by arranging a wrapping layer, the insulation of the cable of the utility model is increased by arranging an insulating layer, the antistatic ability of the cable of the utility model is increased by arranging a fireproof layer, the high temperature resistance of the cable of the utility model is increased by arranging a high temperature resistant layer, the aging resistance of the cable of the utility model is increased by arranging a corrosion resistant layer, and the wear resistance of the cable of the utility model is increased by arranging a wear resistant layer, thereby improving the service life of the cable of the utility model.

[0024] 6. In the present invention, the high temperature resistant layer is made of phenolic foam material. Since phenolic foam has a uniform closed-cell structure, its thermal conductivity is low and its thermal insulation performance is good. Therefore, applying phenolic foam as an interlayer to cold shrink cable accessories can greatly increase the high temperature resistance of the cable of the present invention.

[0025] 7. In the utility model, the corrosion-resistant layer is made of polyolefin synthetic material. Since polyolefin not only has low relative density, good chemical resistance and water resistance, but also has good mechanical strength and electrical insulation, it can effectively increase the aging resistance of the cable.

[0026] 8. In the present invention, the wear-resistant layer is made of polyvinyl chloride synthetic material. Since polyvinyl chloride has excellent weather resistance, ozone resistance, chemical resistance, aging resistance, wear resistance and other excellent properties, it can greatly increase the wear resistance of the cable of the present invention.
