According to the physical structure characteristics of superconducting tapes (such as YBCO, ReBCO, Bi2223 and iron-based superconducting tapes, etc.), the present invention can form a high current, low Superconducting cable with AC loss and mechanical stability. This technical solution needs to obtain the corresponding relationship between the bending radius of the strip itself and the current-carrying capacity according to the characteristics of different superconducting tapes and the side bending performance of different superconducting tapes, so that the superconducting current-carrying The performance degradation is within 5%. A single superconducting tape is first stacked and packaged in multiple layers. The packaging structure can fix the superconducting tape. In the process of bending and transposition of the superconducting tape, the packaging structure plays a role in shaping. At the same time, it also supports and protects the superconducting tape itself, preventing it from being woven into a cable.
