NOVELTY - The utility model claims a light weight superconducting aluminium alloy core vehicle high voltage cable, comprising an aluminium alloy conductor layer, a graphene spraying layer, a lapping layer formed by isolating paper wrapping, an insulating layer, a shielding layer, an isolation layer and a protective layer formed by wrapping the isolation paper, the aluminium alloy conductor layer is set at the innermost side, the graphene spraying layer is set at the outer side of the aluminium alloy conductor layer, the lapping layer is set between the insulating layer and the graphene spraying layer, the shielding layer is set at the outer side of the insulating layer, the isolating layer is set at the outer side of the shielding layer, The protective layer is set on the outer side of the isolated layer. The utility model claims a light weight superconducting aluminium alloy core vehicle high voltage cable, using aluminium alloy conductor to replace the traditional copper conductor, spraying graphene coating on the conductor, the graphene coating can be tightly attached on the conductor outer layer to prevent subsequent processing process coating scuffing, greatly improving the conductor self-load flow when reducing the unit cable weight, and quickly dispersing lead heat in the electrifying process.
