摘要：

A flexible superconducting (SC) busline was developed as a current feeder system for the fusion experimental device, LHD. An aluminum stabilized NbTi/Cu compacted strand cable was developed to satisfy the fully stabilized requirements ata rated current of 31.3 kA. A pair of SC cables was electrically insulated and installed in a cryogenic transfer line. Measured breakdown voltage in the 77 K helium gas is 8.33 kV. Nine sets of SC current feeders with 45-65 m lengths are installed for LHD. The total heat loads into 80 and 4.2 K levels are estimated to be 2.12 and 1.02 kW, respectively. The SC current feeder system is designed to maintain its rated capacities for 30 minutes, whenever the coolants supplied to the current feeder system are accidentally stopped.
