An anti-interference high-voltage cable in a new energy vehicle

Abstract

The invention discloses an anti-interference high-voltage cable in a new energy vehicle, includes a cable body and a core, At that outermost side of the cable body is provide with a first protective sleeve, A corrosion resistant layer is arranged on the inner side of the first protective sleeve, a high-temperature resistant layer is arranged on the inner side of the corrosion resistant layer, a fire-proof layer is arranged on the inner side of the high-temperature resistant layer, a water-proof layer is arranged on the inner side of the fire-proof layer, a shield layer is arranged on the innerside of the water-proof layer, a first insulating layer is arranged on the inner side of the shield layer, and a first high-voltage resistant layer is arranged on the inner side of the first insulating layer. The shielding layer arranged in the invention can absorb the interference electromagnetic wave through the copper wire layer, At the same time, through holes in aluminum foil layer can alsoreflect and absorb the interference electromagnetic wave, further strengthen the anti-interference ability of the cable, and finally, the interference electromagnetic wave can be completely eliminatedthrough stainless steel wire layer.

Description

technical field [0001] The invention relates to the technical field of electric wires and cables, in particular to an anti-interference type internal high-voltage cable for new energy vehicles. Background technique [0002] New energy vehicles refer to the use of unconventional vehicle fuels as power sources (or the use of conventional vehicle fuels, the use of new vehicle power devices), integrated vehicle power control and advanced technology in driving, the formation of advanced technical principles, with Automobiles with new technology and new structure. New energy vehicles include pure electric vehicles, extended-range electric vehicles, hybrid vehicles, fuel cell electric vehicles, hydrogen engine vehicles, and other new energy vehicles. Among them, a pure electric vehicle is a vehicle that uses a single battery as the energy storage power source. It uses the battery as the energy storage power source, and supplies electric energy to the motor through the battery to d...
