AI Technical Summary

Technical Problem

The existing high-temperature superconducting cables have large AC losses due to too close strips and fewer layers of strips, which has a problem of large losses.

Method used

The central support frame and the outer support frame structure distributed with multiple concentric circles are adopted. Through the staggered distribution of axial interlocking strips, inner axial interlocking strips and outer axial interlocking strips, the interlocking stacking of axial superconducting strips, inner superconducting strips and outer superconducting strips is realized. Combined with the rotating sleeve structure, the position of the strip is flexibly adjusted to reduce AC losses.

Benefits of technology

It effectively reduces losses, increases the number of stacked layers of the strip, improves the transmission capacity, and further reduces AC losses through the rotating sleeve structure.
