Abstract

The invention discloses a waterproof electric vehicle charging cable and a preparation method thereof. The waterproof electric vehicle charging cable includes a wire core body, an insulating wrapping layer and an outer sheath arranged from the inside to the outside; the wire core body includes at least Two power lines, at least two auxiliary power lines, signal transmission lines, and grounding lines; wherein, the power lines are composed of silver-plated copper wire conductors and foamed polyperfluoroethylene propylene insulation layers that are sequentially sleeved from the inside to the outside; Moreover, polypropylene filler is filled between the insulation wrapping layer and the core body. The transmission performance of the waterproof electric vehicle charging cable is stable, and the waterproof performance of the cable is excellent, which can prevent the outdoor charging pile from being unable to charge normally due to the weather.

Description

technical field [0001] The invention relates to cables, in particular to a waterproof electric vehicle charging cable and a preparation method thereof. Background technique [0002] Generally speaking, a cable is made of one or more mutually insulated conductors and an outer insulating layer, which transmits power or information from one place to another. With the rapid development of the economy, more and more places need cables to transmit power or other information, so there are stricter requirements for the manufacture of cables. The outer sheath of the cable is an indispensable structural part of the cable, which plays the role of protecting the cable, ensuring the safety of the cable, and isolating the cable core from water, air and other media to avoid leakage. [0003] In particular, outdoor cables for outdoor use and military use have relatively high requirements on their wear resistance and weather resistance, and the outer sheath of the cable is required to have ...
