Embodiment 3

[0050] This embodiment provides a high temperature superconducting cable structure, such as Figure 1-11 , in this embodiment, the support unit 100 is the shell of the high-temperature superconducting cable structure, and an accommodating space 101 is arranged in the middle. Initially, there is a circular inner core, and the superconducting tape unit 200 is wound in a spiral shape. On the circular inner core, the accommodating space 101 of the support unit 100 is slightly larger than this structure, and the support unit 100 is placed on this structure to evenly release the stress of the superconducting tape unit 200, so that its diameter can be controlled and uniformly expanded. After the angle increases to a specified value, the circular inner core is removed, and the superconducting tape unit 200 is wound and attached to the inner wall of the support unit 100 at this time.

[0051] The filling unit 300 is a cryogenic liquid filled after the superconducting tape unit 200 is r...
