It can charge various types of electric vehicles according to the adjusted voltage and current. The charging pile is powered by cables and other means.

[0003] The current charging pile cable is equipped with conductors and connecting wires, etc. In order to prevent the temperature inside the cable from being too high, a cooling tube is generally provided inside the charging pile cable to cool the inside. However, due to the poor anti-extrusion ability of the current charging pile cable, the cooling tube inside the cable is easily squeezed and damaged during use, which has a certain impact on the subsequent use of the cable.

[0026] Furthermore, the second anti-pressure blocks 11 are distributed in an annular and equidistant manner on the surface of the sheath 10, and the surfaces of the sheath 10 and the second anti-pressure blocks 11 are both provided with a wear-resistant layer. The second anti-pressure blocks 11 are made of rubber material, which has good elasticity and buffering properties and can effectively absorb and buffer external pressure.

[0027] Furthermore, the wear-resistant layer is polyvinyl chloride coating. Polyvinyl chloride coating is a polymer coating formed by the polymerization of vinyl chloride monomer and has good wear resistance. When the cable surface is coated with polyvinyl chloride coating, its wear resistance will be significantly improved, thereby effectively extending the service life of the cable. In addition, polyvinyl chloride coating also has excellent chemical resistance, weather resistance and insulation properties, can resist corrosion from various chemical substances, and prevent the cable from being eroded and damaged by the external environment.
