Mill, intolerant to puncturing, traditional cable is when on new-energy automobile, due to needing to bend, generallys use poling working process, and high
Temperature reaches that 180 degree tubing is usually harder, and bending radius is big, mismatches with silicone rubber kinds cable, and traditional cable once used glass
It is coated after silk braiding, is generally forbidden using in the cable by environmental protection and safety requirements, glass fiber.And aramid fiber weaves rear protecting
Layer, since surface is smooth, coating is difficult, and surface is not smooth enough, and coating is not uniformly leaky enough.Using the utility model patent
Silicone Rubber Coated lotion can perfectly solve problem above, and surface coating thickness is between 0.1-0.15 millimeters, coating surface
Uniformly, beautiful, can be with effective solution silicone rubber jacket surface not antifriction and the characteristics of puncture, cable does not need poling, can be with
It directly uses, cable entirety is more soft, heatproof is high.After vehicle factor cuts out line, it can be mounted directly connection, it is convenient and efficient.With 50mm2
For automobile high-voltage line, using the utility model structure, the cost than traditional perforating tube structure reduces by 5~8%, income compared with
It is high.
The foregoing is merely the preferred embodiments of the utility model patent, are not intended to limit the utility model patent model
Enclose, it is all using equivalent structure or equivalent flow shift made by the utility model patent specification and accompanying drawing content, or directly or
Other related technical areas are used in indirectly, similarly include in the utility model patent protection scope.
