Description

technical field [0001] The invention specifically relates to a high-voltage superconducting wire and cable. Background technique [0002] Superconducting materials are materials that exhibit the property of zero resistance under certain low temperature conditions, and are widely used in the production of magnets and power cables. [0003] With the development of superconducting materials, the second-generation superconducting wires appear. Its typical structure consists of a substrate, a buffer layer, a superconducting layer and a stabilization layer. Among them, the substrate is the support of the entire superconducting wire; the buffer layer and It is called the middle layer, and its role is to provide texture for the growth of the superconducting layer; the superconducting layer is formed of superconducting materials and is the carrier of current; the stabilization layer is also called the stable layer, and its role is to protect the superconducting layer, which is genera...

AI Technical Summary

Problems solved by technology

The uneven thickness of the central part 51 and the edge part 21 of the Cu layer will increase the contact resistance of the welding part when the obtained superconducting wire is welded to the electrode, which will affect the superconducting performance of the superconducting wire

[0004] In addition, due to the fact that the existing wires and cables consume a large amount of electricity during the power transmission process, the reason is that the power consumption cannot be reduced due to the poor conductivity of the material.
