Description

technical field [0001] The invention relates to the field of an electrified conductor, in particular to an electrified conductor of a CORC superconducting cable. Background technique [0002] Compared with conventional power cables, superconducting cables have the advantages of low AC loss, strong current capacity, compact structure, and small size. For the high-power and long-distance transmission of electric energy in the future power system, the application of superconducting cables is of great significance. Compared with low-temperature superconducting tape (LTS), the second-generation high-temperature superconducting tape (HTS) has excellent performance and strong current-carrying capacity, so in power grid applications, HTS is the most likely candidate material. [0003] The development of high-strength high-temperature superconducting cables has been hindered due to the mechanical limitations of the high aspect ratio and planar shape of the superconducting tape, as w...
