Title:

WEAR-RESISTANT, TORSION-RESISTANT AND ENVIRONMENTALLY FRIENDLY CABLE FOR ELECTRICAL VEHICLE CHARGING AND PREPARATION METHOD THEREFOR

Document Type and Number:

WIPO Patent Application WO/2019/042009

Kind Code:

A1

Abstract:

Disclosed are a wear-resistant, torsion-resistant and environmentally friendly cable for electrical vehicle charging and a preparation method therefor, comprising the following steps: twisting of conductors, insulation extrusion, cabling with a shield layer, a liner layer and a wire core, and sheath extrusion. The present solution employs a high-performance ethylene propylene rubber material self-developed as an insulation material of a cable, and an excellent-performance elastomer material as a sheath material, which can withstand frequently-changed high and low temperatures, has excellent climate resistance and ultraviolet light resistance performance, and can be used outdoors for a long time. The cable has excellent wear resistance, winding resistance and mobile fatigue resistance performance. A rational structure design is employed: the rational layout and twisting of the insulated wire cores ensure that the cable has torsion resistance properties at normal temperature and low temperature. The overall service environment performance of the cable and the anti-aging service life of the cable are improved, and the service life of the cable is up to 10 years.
