Abstract
The invention discloses a low-loss high-temperature superconducting strand, which consists of a superconducting tape set, a metal filler and a metal sleeve, wherein the superconducting tape set is formed by tightly stacking second-generation high-temperature superconducting REBCO (rare earth barium copper oxide) coated conductors after special treatment. The innermost layer of the low-loss high-temperature superconducting strand is a superconducting strip group, the outermost layer of the low-loss high-temperature superconducting strand is a metal sleeve, and a gap between the superconducting strip group and the metal sleeve is filled with metal fillers. In the folded yarn, the REBCO superconducting tape is subjected to laser drilling treatment, so that the loss of the superconducting tape during current transmission can be effectively reduced. The low-loss high-temperature superconducting stranded wire has lower loss and extremely high engineering application prospect.
