The current feeding system for superconducting magnets of JT-60SA were designed. Key components concerned were developed and tested. Trial manufacturing of crank shaped feeder to reduce the thermal stress showed the max. dimensional error of 3 mm. The compact tool to connect the feeder joint with solder vertically was developed. The joint resistance of feeder joint sample was 2n within the requirement of 5n. Feeder insulation samples showed sufficient shear strength. Since all the manufacturing processes concerned were confirmed, the production of CTBs and feeders can be started.
