High temperature superconductor (HTS) current leads are key components of the ITER magnet system, transferring large current from room-temperature power supplies to very low-temperature superconducting coils at minimal heat load to the cryogenic system. The HTS current leads for the ITER Tokamak are supplied by Chinese Domestic Agency through KEYE Company affiliated to the Institute of Plasma Physics (ASIPP).

Following the signature of the feeder procurement arrangement in January 2011, KEYE launched a string of activities to prepare for series production. These included the qualification of critical manufacturing technologies through targeted trials in mockups, which will conclude with the manufacturing and testing of several pairs of current lead prototypes this year.
Just in time for the Chinese New Year festivities, KEYE successfully completed the production of a pair of correction coil 10kA current lead prototypes and delivered them to ASIPP for test. Subsequent two long weeks of testing showed that this pair of current leads is wonderful.
