Superconducting conductor joint technology is one of the key technologies of CICC conductors. In the past 30 years of CICC conductor development, research and development of superconducting conductor joints with various structures has been carried out. The Institute of Plasma Physics, Chinese Academy of Sciences is currently building a conductor test device for the ITER program correction coil (Correction Coil, CC). To avoid the use of bulky and expensive DC power supplies and current leads, the test setup uses superconducting transformers instead of conventional power supply systems. Superconducting transformers can generate currents up to 50kA.
