Cable for new energy vehicle

Abstract

The invention discloses a cable for a new energy vehicle, and belongs to the field of new energy vehicles. The cable comprises a conductor, an internal belting layer, an insulating layer, a tensile layer, a shielding layer, an external belting layer and a sheath which are arranged in sequence from inside to outside in the radial direction. By means of the internal belting layer and the external belting layer, the conductor and a woven part are more rounding and compact, and the phenomenon that the conductor loosens or becomes oval, so that the performance is lowered, and the high pressure resistant effect of the cable is affected can be effectively avoided; by means of the tensile layer, the tensile strength of a wire can be increased, and meanwhile the effect that acute angle bending is conducted without cracking is achieved; by means of the shielding layer, the very high shielding effect is achieved, and low-frequency interference can be more effectively resisted.

Description

technical field [0001] The invention belongs to the field of new energy vehicles, in particular to a cable for new energy vehicles. Background technique [0002] Nowadays, most of the high-voltage power cables in new energy vehicles use insulation or sheath materials with a rated temperature of 125 degrees Celsius. There will be sharp changes and the resulting temperature is very high, so the temperature level of the cable is required to be high, which needs to reach 150 degrees Celsius, and it is required to meet the application requirements of long-term high bending. The current materials of high-voltage cables in new energy vehicles cannot fully meet the application requirements, and there are large electrical safety hazards. [0003] In the market, the cables provided by the prior art are easy to oxidize, and the conductors are easy to loose, resulting in poor high-voltage resistance of the cables and low tensile strength, bending strength, and environmental performance...

The current materials of high-voltage cables in new energy vehicles cannot fully meet the application requirements, and there are large electrical safety hazards

[0003] In the market, the cables provided by the prior art are easy to oxidize, and the conductors are easy to loose, resulting in poor high-voltage resistance of the cables and low tensile strength, bending strength, and environmental performance.

[0004] New energy vehicle cables are one of the essential and important components in the automotive power transmission system. With the extensive application of automotive electrical appliances and modern control technology, the automotive power transmission system is becoming more and more complex. On the one hand, there are frequency conversion in the power and control systems inside the car. components such as transformers, transformers, and high-power motors, and such components are often accompanied by low-frequency interference, which will cause interference to the automotive electronic control system and instrumentation, causing damage to or even failure of the automotive control system. lead to security incidents
