Low-temperature-resistant waterproof charging pile cable and production process

Abstract

The invention discloses a low-temperature-resistant waterproof charging pile cable, which comprises a conductor formed by twisting a plurality of core wires, and further comprises an outer cover, wherein a braided layer is braided on the surfaces of the core wires, the surface of the braided layer is coated with a middle cover, the surface of the conductor is wound with a water-blocking tape, thesurface of the water-blocking tape is coated with an insulating sleeve, an aluminum-plastic composite tape is attached to the inner wall of the outer cover, a water-blocking material is filled in thealuminum-plastic composite tape and located between the outer surfaces of the insulating sleeve, and the water-blocking tape is prepared by using a polyester non-woven fabric as a base cloth and adding a water-absorbing polymer rubber and a plastic coating material. The invention relates to the technical field of charging pile cables. According to the low-temperature-resistant waterproof chargingpile cable and the production process, the cable body of the low-temperature-resistant waterproof charging pile cable is still soft even when the low-temperature-resistant waterproof charging pile cable is used at the temperature of minus 40 DEG C, so that the low-temperature-resistant waterproof charging pile cable adapts to severe cold environments in northeast China, North America and North European China, waterproofness of the charging cable is improved, and hidden danger of water entering the cable is avoided.

Description

technical field [0001] The invention relates to the technical field of charging pile cables, in particular to a low temperature resistant waterproof charging pile cable and a production process. Background technique [0002] Today, with the increasing number of new energy vehicles, new energy and green travel have gradually become a new way of life, and more and more charging piles appear in life, so the standard electric vehicle DC (AC) charging pile cable has become the " heart". [0003] Referring to the charging pile cable with the Chinese Patent Publication No. CN107195363A, through the cable core formed by the main core, the center line, the high temperature warning core and the control signal core, the hollow part of the cable core is filled with TPE rubber filling strips, and the outer part of the cable core is The outer sheath layer is extruded; the high temperature early warning core is a temperature-sensing iron wire; the control signal core is composed of at lea...

AI Technical Summary

Problems solved by technology

[0007] Aiming at the deficiencies of the prior art, the present invention provides a low-temperature-resistant waterproof charging pile cable and its production process, which solves the problem that the existing ordinary charging cables are easy to harden in cold winter and have poor waterproof performance, especially in wet, rainy conditions. In many places, there is a hidden danger of water ingress in the cable
