Abstract

The invention provides a superconducting tape suitable for a superconducting current lead, the superconducting current lead and a preparation method thereof. The superconducting tape comprises a substrate comprising a first surface and a second surface, wherein a superconducting layer is connected on the first surface. The surface of the superconducting layer is coated with a silver layer. The twoends of the superconducting layer are welding areas, and the surface of the welding areas is coated with a copper layer. The heat leakage rate of the superconducting current lead manufactured by themethod is reduced by half or even an order of magnitude in comparison with the existing superconducting current lead.

Description

technical field [0001] The invention relates to the field of superconducting materials, in particular to a superconducting tape suitable for a superconducting current lead, a superconducting current lead and a preparation method. Background technique [0002] In recent years, high-temperature superconducting power leads have been paid more and more attention by people. The binary current leads made of high-temperature superconducting materials, when the superconducting material works below the critical temperature, because it is in a superconducting state, there is no Joule heat generation. Due to the low thermal conductivity of the material itself, it can greatly reduce the conduction heat leakage. Therefore, using high-temperature superconducting materials to make current leads has become the best choice for superconducting applications. [0003] High-temperature superconducting materials are divided into the first generation and the second generation. The first generatio...
