Problems solved by technology

[0003] The use of superconductors to make cables can reduce power operating costs. Under the same cross-section, high-temperature superconducting cables can transmit three to five times more power than conventional cables. Due to the general mechanical properties of superconductors, the existing superconducting cables Superconductors are generally used with skeletons, but the thermal expansion coefficients of skeletons and superconductors are different. This kind of structure can easily lead to superconducting strips being stretched too tight or too loose, and even have serious consequences of superconducting strips being broken, deformed and damaged.
