Power cable for new energy vehicle

Abstract

The invention discloses a power cable for a new energy vehicle. The power cable for a new energy vehicle includes a cable core, wherein the cable core comprises four square rubber skeletons each of which has a square cross section; the each square rubber skeleton is double-layered, and a cavity is formed between the inner side and the outer layer; the centers of four surfaces of the each square rubber skeleton are bent inward; a plurality of cores 1 are arranged in the cavity of the each square rubber skeleton, and each corner in the cavity is provided with a polyurethane elastic rod; a core 2is arranged at the center of each square rubber skeleton; the four square rubber skeletons are spliced into a square cable core; and three layers of galvanized steel tape armor layer, a nano siliconwaterproof rubber filling layer, a Kevlar fiber braid layer and a halogen-free low smoke flame retardation polyolefin oversheath are sequentially coated on the outer side of the cable core. The powercable for a new energy vehicle combines four square skeletons, and each square skeleton has a double-layer structure, and the cores are arranged inside the skeletons to make the structure tidier, andthe cable can be compression resistant and tension resistant.

Description

technical field [0001] The invention relates to the technical field of cables for automobiles, in particular to a power cable for new energy automobiles. Background technique [0002] With the rapid development of the new energy industry, electric-driven vehicles are gradually replacing traditional vehicles, and charging pile equipment is laid on a large scale, widely distributed in residential areas and public places. However, such charging piles are mostly distributed in open-air environments. After working for a long time, due to exposure to the sun and rain, it is very easy to cause a short-circuit fire, seriously damage the internal precious electronic devices of the new energy vehicle, and threaten personal and property safety. Contents of the invention [0003] The purpose of the present invention is to provide a power cable for new energy vehicles in order to remedy the defects of the prior art. [0004] The present invention is achieved through the following tech...
