Internal high-voltage cable for electric automobile

Abstract

The invention discloses an internal high-voltage cable for an electric automobile. The internal high-voltage cable comprises a conductor, wherein the conductor is arranged at the center in the cable; an insulating layer is extruded outside the conductor; a sheath layer is extruded on the outermost layer; a first isolating layer and a second isolating layer are sequentially extruded outside the insulating layer; a tinned copper wire shielding layer and an aluminum foil shielding layer are respectively braided between the first isolating layer and the second isolating layer; and a group of symmetrical carbon fiber strengthening cores is arranged in the conductor and is coated with an elastic plastic protection layer. The internal high-voltage cable for the electric automobile has the advantages of excellent heat resistance, abrasive resistance, oil resistivity, acid and alkali resistance, no halogen, environmental protection, good flexibility, long service lifetime, high voltage resistance, high current capacity, stable power transmission quality and the like, can prevent electrical disturbance and can meet a long-term safe operation of the electric automobile.

Description

technical field [0001] The invention relates to an electric vehicle cable, in particular to an electric vehicle interior high-voltage cable. Background technique [0002] Facing the increasingly severe pressure of energy conservation and emission reduction, and the rapid increase of traditional gasoline vehicles, their exhaust emissions cause air pollution, resulting in an increase in smog weather. New energy electric vehicles have developed rapidly due to their energy saving and environmental protection. At present, the state has also introduced multiple measures to support the development of new energy electric vehicles. It is expected that the new energy vehicle industry will develop rapidly in the next few years. The high-voltage cable in the electric vehicle is used as the high-voltage connection cable for the battery and motor in the electric vehicle. It is still in the research and development stage, and most of them are replaced by traditional power cords. However, ...

AI Technical Summary

Problems solved by technology

However, conventional cables cannot meet their use requirements in terms of temperature resistance, high-voltage impact resistance, scratch resistance and vibration resistance, flexibility, electromagnetic compatibility, and halogen-free environmental protection, resulting in various problems and safety hazards exposed during the use of cables. In addition, the cable core of the existing high-voltage cable in the vehicle is easily broken when it is laid or bent, which causes great inconvenience to the laying and increases the cost and labor force.
