The invention provides a flexible cable for a new energy automobile. The flexible cable comprises an insulating wire core, wherein an inner protective layer is coated outside the insulating wire core,and a fireproof isolation layer, a heat insulation layer, a shielding layer and a flexible outer protection layer are sequentially arranged outside the inner protection layer. According to the invention, due to the fireproof layer and the fireproof isolation layer, the cable has excellent high temperature resistance and fireproof performance, and high flame retardancy of the cable is ensured; theheat insulation layer can reduce the influence on the transmission performance of the cable caused by the conduction of external heat to the conductor of the cable; the shielding layer enhances the external electromagnetic interference resistance of the cable, improves the working stability of the cable, and enables the signal transmission to be stable; and through the flexible outer protection layer, the mechanical performance of the cable is remarkably improved, the flexibility of the cable is improved, the flexible outer protection layer comprises glass fiber yarn and silicon carbon, and the two materials have excellent fireproof performance, so that the fireproof performance of the flexible cable for the new energy automobile is further improved.

    本发明提供一种新能源汽车用柔性电缆,其包括一绝缘线芯,绝缘线芯外包覆有一内护层。所述内护层外依次设置有一防火隔离层、一隔热层、一屏蔽层和一柔性外护层。所述防火层及所述防火隔离层,使得该电缆具有优异的耐高温及防火性能,保证电缆的高阻燃性。所述隔热层使得可以减少外界的热量传导至电缆的导体处,影响电缆的传输性能。所述屏蔽层增强了电缆抵抗外界电磁干扰的能力,提高了电缆的工作稳定性,使得信号传输稳定。所述柔性外护层显著提高了电缆的机械性能同时增加其柔软度,同时,柔性外护层包含玻纤纱和硅碳两种材料,两种材料均具有优良的防火性能,也使本新能源汽车用柔性电缆的防火性能得到进一步提升。
