A crosslinked elastomer insulation sheath new energy vehicle internal high-voltage cable

Abstract

The invention provides a crosslinked elastomer insulation sheath new energy vehicle high-voltage cable, which comprises a central high-temperature skeleton, a heat insulating pipe, a high-temperatureresistant layer, a total shielding layer and an outer sheath; the cross-linking elastomer insulation sheath comprises a central high-temperature resistant skeleton, a heat insulating pipe, a high-temperature resistant layer and an outer sheath. A central high-temperature resistant skeleton is arranged inside the heat insulating pipe, the heat insulating pipe comprises a plurality of V-shaped segments which are circumferentially distributed and connected with each other around a central high-temperature resistant skeleton, the V-shaped section is internally provided with a first conductor whichabuts against the central high-temperature resistant skeleton, A high temperature resistant layer, a total shielding layer and an outer sheath are wrapped on the outside of the heat insulating pipe in turn, and a plurality of V-shaped segments of the heat insulating pipe are abutted against the inner side of the high temperature resistant layer, and a second conductor abutted against the high temperature resistant layer and two V-shaped segments is arranged between any two adjacent V-shaped segments. The heat generated by the work of the second conductor can be quickly dissipated in the gap between the heat insulating pipe and the high-temperature resistant layer, and the heat resistance of the cable is improved. The heat generated by the work of the second conductor can be quickly dissipated in the gap between the heat insulating pipe and the high-temperature resistant layer.

Description

technical field [0001] The invention relates to the technical field of automotive cables, in particular to a cross-linked elastomer insulating sheath for high-voltage cables in new energy vehicles. Background technique [0002] The high-voltage cable of new energy electric vehicles is the bridge for power transmission inside the vehicle, and it occupies an indispensable seat in new energy vehicles. However, spontaneous combustion of automobiles has always occurred frequently, and the main reason is the fire of automobile circuits. Due to the small space inside the automobile and the large outer diameter of some cables, the arrangement of the circuits is uneven, and the heat resistance of the cables is not good, so it cannot achieve a good performance. The heat dissipation effect will cause the circuit to catch fire and the car to spontaneously ignite. Contents of the invention [0003] Based on the technical problems existing in the background technology, the present inve...
