AI Technical Summary
Existing copper-silver clad superconducting tapes form an alloy at high temperatures, which limits their superconducting performance compared to pure silver clad tapes, thus restricting performance improvements.
The hardness of the outer sheath is increased by rolling the superconducting wire in a cooling medium or by rolling the superconducting tape together with a harder metal tape, thereby increasing the hardness and texture of the superconducting core material and thus improving the superconducting current transmission performance.
The hardness and texture of the superconducting tape were improved, enhancing the superconducting current transport performance. The porosity of the superconducting core material was reduced, and the grain arrangement was more orderly, thus improving the superconducting performance.
