A flexible superconducting (SC) bus-line with total length of 497 m was installed as a current feeder system for the experimental fusion device, LHD. A thermal contration of the SC cables of 180 mm can be absorbed in the structure of the SC bus-lines. The total heat loads into 80 and 4.2 K level are estimated to be 2.12 and 0.48 kW, respectively, including the evaporation of 650 L/h. The SC current feeder system and the cryogenic components of the LHD will be cooled Down simultaneously.
