Wear resistant cable for charging pile and manufacture method therefor

Abstract

The invention discloses a wear resistant cable for a charging pile and a manufacture method therefor. The wear resistant cable for the charging pile includes a cable inner core and a cable outer layer covering the cable inner core. The cable inner core comprises a power supply cable, a protective grounding cable, a middle line cable, a pair of control / charging connection confirmation cables and a pair of standby expansion cables. Double shielding layers cover the pair of control / charging connection confirmation cables. The cable outer layer is composed of a wrapping belt, a TPE inner sheath, and a TPU outer sheath in turn from inside to outside. The cross section of the TPE inner sheath is round, and the cross section of the TPU outer sheath is concavo-convex. The wear resistant cable for the charging pile has the advantages of compact structure, good stability, no halogen and low smoke, non-toxicity, corrosion resistance, stretch resistance, bending resistance and friction resistance. The sheath layer employs TPE and TPU sheaths and has wide hardness scope, excellent stainability, soft touch, and good weatherability, fatigue resistance, temperature toleration and mechanical property.

Description

technical field [0001] The invention relates to cable technology, in particular to a wear-resistant cable for a charging pile and a manufacturing method thereof. Background technique [0002] As we all know, new energy vehicles are one of the seven national strategic emerging industries determined by China's "Twelfth Five-Year Plan", and it is also an inevitable trend in the development of the world's automobile industry. [0003] On July 25, 2012, "China's new energy vehicles' multiple 'new policies' will have a major impact". The State Council recently issued the "Guiding Opinions on Accelerating the Promotion and Application of New Energy Vehicles", proposing 25 specific policy measures in 6 aspects, deploying to further accelerate the promotion and application of new energy vehicles, ease the pressure on energy and the environment, and promote the transformation and upgrading of the automobile industry. [0004] According to the relevant plan issued by the State Council...

AI Technical Summary

Problems solved by technology

[0010] 1. The existing charging pile cable sheath material is basically TPE material, but TPE material has poor wear resistance and weather resistance

[0011] 2. The sheath of the charging pile cable is round now, but the round cable is poor in drag and wear resistance

[0012] 3. The filling material of the current charging pile cable is polypropylene mesh torn fiber rope (PP rope), but the tensile performance and bending resistance of the current PP rope are poor
