Problems solved by technology

However, the current development of superconducting wires/tapes and cables also faces some technical problems, which need to be further optimized and improved. It is necessary to further improve the mechanical strength, flexibility, lateral bending and processability of the superconducting wire/ribbon, so that the manufactured superconducting wire/ribbon has a certain uniformity and performance stability; when there is any type of mechanical disturbance, Thermal disturbance or magnetic disturbance, as well as the fault current of the power system, have a certain impact on the superconducting wire/strip and superconducting cable, which will cause a quench problem; Or take system downtime, the economic loss will be huge
In view of the complexity of the superconducting wire/strip and cable system, the relatively harsh operating conditions, and the rapid development of quenching, the superconducting wire/strip and cable of the cur

Abstract

The present invention relates to a superconductive graphene composite film line/strip and a superconductive graphene composite cable. The superconductive graphene composite film line/strip and the superconductive graphene composite cable comprise a superconductive graphene composite film line/strip and a superconductive graphene composite cable. The superconductive graphene composite film line/strip comprises a graphene layer, a superconductive film layer, a buffer layer, a base material layer and a stable layer. A multi-layer graphene layer comprises a transverse graphene layer and a vertical graphene layer. The transverse graphene layer and the vertical graphene layer of the multi-layer graphene layer are connected with the superconductive film layer, the buffer layer, the base material layer and the stable layer to commonly form graphene latticed composite superconductive film coordination structure body line/strip. The superconductive graphene composite film line/strip comprises a single-face superconductive graphene composite film line/strip and a dual-face superconductive graphene composite film line/strip. The superconductive graphene composite cable has the coordination structure body features of the graphene latticed composite superconductive line.
