Flexible oil-resistant dual-layer high-voltage cable for new-energy vehicle

Abstract

The invention discloses a flexible oil-resistant dual-layer high-voltage cable for a new-energy vehicle. A six-type-conductor in a compound stranding form is adopted and is coated with an insolating layer, the isolating layer is coated with a silicon gel layer, the silicon gel layer is coated with a tinned copper weaving shielding layer, the tinned copper weaving shielding layer is coated with analuminum foil shielding layer, and the aluminum foil shielding layer is coated with an XLPO insulation layer. The insulation layer is formed by winding cotton paper around the six-type-conductor, andthe weaving angle of the tinned copper weaving shielding layer is 50 degrees. The overlapping ratio of the cotton paper winding is larger than or equal to 30%, and the moisture absorption rate of thecotton paper is smaller than 3%. The flexible oil-resistant dual-layer high-voltage cable has the advantages that the flexibility is high, the insulation layer does not easily crack, the interferenceis not generated, and the flexible oil-resistant dual-layer high-voltage cable is suitable for being widely applied and popularized.

Description

technical field [0001] The invention relates to a soft and oil-resistant double-layer high-voltage cable for new energy vehicles, which belongs to the technical field of electric wires and cables. Background technique [0002] New energy vehicles refer to vehicles that use unconventional fuels as power sources, integrate advanced technologies in vehicle power control and drive, and form advanced technical principles, new technologies, and new structures. [0003] At present, the global energy and environmental systems are facing enormous challenges. As a major contributor to oil consumption and carbon dioxide emissions, automobiles are in urgent need of revolutionary changes. At present, the development of new energy vehicles in the world has formed a consensus. In the long run, pure electric drive including pure electric and fuel cell technology will be the main technical direction of new energy vehicles. In the short term, gasoline-electric hybrid, plug-in Hybrid will be ...

AI Technical Summary

Problems solved by technology

[0005] 1. It is not soft enough and inconvenient to assemble; or it is forced to assemble by external force, which has a large stress; it will lead to cracking of the cable insulation layer in a high temperature and high humidity environment;

[0006] 2. During operation, super large current passes through the high-voltage cable, resulting in low-frequency interference

[0007] The above technical problems have brought inconvenience to the use of high-voltage cables, and hindered the promotion and development of new energy vehicles to a certain extent
