Flexible super-A-class aluminum alloy core in-vehicle high-voltage cable for new energy automobile

Abstract

The invention relates to the technical field of cables, in particular to a flexible super-A-class aluminum alloy core in-vehicle high-voltage cable for a new energy automobile. The high-voltage cablecomprises an aluminum alloy conductor, a first lapping isolation paper layer, an anti-peeling silicon rubber insulating layer, an aluminum-plastic composite belt shielding layer, a tinned copper wirebraid layer, a second lapping isolation paper layer, a ceramic silicon rubber inner sheath and an outer sheath, wherein the first lapping isolation paper layer, the anti-peeling silicon rubber insulating layer, the aluminum-plastic composite belt shielding layer, the tinned copper wire braid layer, the second lapping isolation paper layer, the ceramic silicon rubber inner sheath and the outer sheath sequentially wrap the outside of the aluminum alloy conductor, and the outer sheath 8 is a glass fiber yarn layer and carbon-silicon composite coating. The high-voltage cable is good in flexibilityand shielding performance, environmentally friendly, non-toxic and excellent in fire resistance.

Description

technical field [0001] The invention relates to the technical field of cables, in particular to an in-vehicle high-voltage cable for a new energy vehicle with a flexible super-A aluminum alloy core. Background technique [0002] With the rapid development of new energy vehicles, the demand for high-voltage cables in new energy vehicles is also increasing. The traditional low-smoke, halogen-free, flame-retardant cross-linked polyolefin insulated high-voltage cables in vehicles are not very ideal in terms of flexibility and flame retardancy. . Due to the limited space of the electric vehicle connection device, the requirements for the bending radius of the cable are relatively high, which requires the cable to be flexible. The traditional low-smoke, halogen-free, flame-retardant cross-linked polyolefin insulated high-voltage cables in the vehicle can no longer meet the needs of customers. At the customer's installation site, the cables are often too hard to bend, which affect...
