Abstract

The invention discloses a cable for DC charging of an electric vehicle, which comprises a cable core and a sheath layer covering the outside of the cable core. The raw materials of the sheath layer include 5-15 parts by weight of styrene-butadiene rubber, 30-50 parts of ethylene, 2-12 parts of polyamide resin, 1-3 parts of tetraisopropyl bis(dioctyl phosphite) titanate, 4,4-bis-(tert-butylperoxy)valeric acid 2-4 parts of butyl ester, 3-5 parts of vulcanization aid, 2-5 parts of anti-aging agent, 65-75 parts of filling and strengthening agent. The invention has excellent wear resistance and tear resistance, and has a smaller bending radius and superior bending resistance. The automatic take-up and take-up device is used for take-up and take-up. The take-up and take-up takes up little space, and the take-up and take-up is convenient for storage. The difficulty of using and storing is reduced.

Description

technical field [0001] The invention relates to the technical field of cables, in particular to a cable for DC charging of an electric vehicle. Background technique [0002] The electric vehicle DC charging system cables in the prior art include power transmission conductors, grounding conductors, auxiliary power conductors, signal control conductors, insulating layers, inner sheaths, shielding layers, outer sheaths, etc. Significant, it is difficult to take in and out the cable, the storage takes up a lot of space, and it is not easy to recycle. However, the cable sheath material is often subjected to friction and pulling when the cable is retracted and unwound, and has high requirements for wear resistance and tear resistance, which need to be solved urgently. Contents of the invention [0003] Based on the technical problems existing in the background technology, the present invention proposes a cable for DC charging of electric vehicles, which has excellent wear resis...
