Fabrication and properties of 500A class multistrand conductor for HTS power cable

고온초전도 전력케이블용 500A급 코어 도체 제조 및 특성실험

High T$_c$ (${\sim}$21,500 A/cm$^2$, at 77K) of 100m length of BSCCO 2223 tapes have been achieved using optimized precursor powders with carefully controlling variables in heat treatment. Prototype 500A class multistrand conductor for HTS power cable was fabricated using these tapes. Also discussed are the transportation properties of prototype 500A class multistrand conductor.
