Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Please see Figure 1A liquid-cooled supercharging pile cable copper conductor includes a copper conductor 1, which is manufactured using the Niehoff electroplating process. After the final stranding process, the diameter of the single wire is 0.150±0.002mm, the DC resistance is ≤0.264Ω / km, and the weight per meter is ≤664.59g / m. A tin-plated layer 2 is fixedly provided on the outer side of the copper conductor 1. Tin plating of the copper wire is mainly to prevent the copper from oxidizing in the air and forming verdigris, which has poor conductivity and increases resistance. Tin-plated copper wire can prevent oxidation-reduction reaction, increase heat dissipation, improve conductivity, and improve wire performance. A control wire core 3 is fixedly provided above the copper conductor 1. The control wire core 3 is made of low-oxygen copper rods produced by continuous casting and rolling, stretched by Niehoff multi-head drawing equipment, with an elongation of ≥20%, 7-16 strands, and a wire diameter range of 0.150-0.250mm. A first insulation layer 4 is fixedly installed on the outer layer of the control wire core. A signal core 5 is fixedly installed below the body 1. The signal core 5 is made of oxygen-free copper with excellent conductivity, dry stretching, resistivity ≤0.017000, and wire diameter range of 0.80-2.75mm. A second insulation layer 6 is fixedly installed on the outer layer of the signal core 5. A shielding layer 7 is fixedly installed on the outer layer of the second insulation layer 6. A filling layer 12 is fixedly installed on the outer layer of the copper conductor 1, control core 3, and signal core 5. The filling layer 12 is made of cotton thread. A cooling pipe 8 is fixedly installed on the outer layer of the filling layer 12. The cooling water pipe uses coolant to cool the copper conductor, remove the heat generated by its own resistance loss when transmitting current, and improve the current transmission efficiency. This cable can achieve ultra-fast charging, speed up transmission speed, and improve transmission efficiency. A buffer layer 9 is fixedly installed on the outer layer of the cooling pipe 8. A wrapping layer 10 is fixedly installed on the outer side of the buffer layer 9. A rubber sheath layer 11 is fixedly installed on the outer side of the wrapping layer 10.

[0018] In summary, the copper conductor of this liquid-cooled supercharging pile cable, by setting an insulation layer, a buffer layer, and a wrapping layer, compared with existing technologies, has the advantages of an insulation layer that provides insulation protection, accelerates transmission speed, and improves transmission efficiency; a buffer layer that effectively prevents internal damage to the cable caused by collisions during installation or use, greatly improving the protection performance of the copper conductor; and a wrapping layer using a copper wire shielding braid that effectively resists some external electromagnetic interference, effectively preventing electromagnetic interference caused by external electromagnetic fields during power transmission.
