Low-smoke halogen-free crosslinked polyethylene high-voltage cable for new energy automobile

Abstract

The invention discloses a low-smoke halogen-free cross-linked polyethylene high-voltage cable for a new energy automobile, which comprises a low-smoke halogen-free cable sheath main body and a new energy automobile frame body, the inner wall of the low-smoke halogen-free cable sheath main body is provided with a separation layer, a conductor is arranged in the low-smoke halogen-free cable sheath main body, and the new energy automobile frame body is provided with a low-smoke halogen-free cable sheath main body. The conductors are uniformly distributed in the low-smoke halogen-free cable sheath main body, the outer sides of the conductors are all provided with the insulating layers, and the low-smoke halogen-free filling strips are arranged in the low-smoke halogen-free cable sheath main body. According to the low-smoke halogen-free crosslinked polyethylene high-voltage cable for the new energy automobile, heat can be generated when the cable is electrified for use, the fire catching phenomenon caused by the heat can be effectively reduced through the material of the low-smoke halogen-free cable sheath main body, and the low-smoke halogen-free filling strips and the low-smoke halogen-free filling balls can effectively play an auxiliary role in insulation, so that the low-smoke halogen-free crosslinked polyethylene high-voltage cable for the new energy automobile can be effectively prevented from being damaged, and the service life of the low-smoke halogen-free crosslinked polyethylene high-voltage cable is prolonged. The safety of the cable when the cable is used on an automobile is effectively ensured, and the possibility that poison gas is released when the cable is on fire is effectively reduced.

Description

technical field [0001] The invention relates to the technical field of cables for new energy vehicles, in particular to a low-smoke, halogen-free cross-linked polyethylene high-voltage cable for new energy vehicles. Background technique [0002] High-voltage cable is a kind of power cable, which refers to the power cable used to transmit 1kv-1000kv. It is mostly used in power transmission and distribution. Now high-voltage cables are suitable for new energy vehicles. High-voltage cables are from the inside to the outside. Including: conductor, insulation, inner sheath, filler (armoring), outer insulation. Of course, armored high-voltage cables are mainly used for underground burial, which can resist high-intensity pressure on the ground and prevent damage from other external forces. However, most of the existing high-voltage cables for new energy vehicles use conventional materials. Even for bare wires, due to the poor heat resistance of conventional materials, a large amou...
