▎ 摘　　要

NOVELTY - Combined tinned copper stranded wire comprises a copper frame, a conductor layer and an insulating layer arranged from inside to outside. The conductor layer is a superconducting belt material and is wound around the copper frame. The superconducting strip includes a metal substrate, a relaxation layer and a superconducting layer and the conductor layer is connected with the copper frame in parallel. USE - Used as combined tinned copper stranded wire. ADVANTAGE - The wire: adopts a combined structure of a superconductor and a copper frame, which can act as a shunt when the copper frame passes a large current, and the superconductor does not consume electric energy and has low resistivity.
