Abstract

Cabling and filament stacking technology has been developed for Bi-based HTS composite wire. Concentric round cabling as well as Rutherford cabling has been proven in >100m lengths. For Bi-2223 precursor composite wire, post-cabling deformation is required to achieve high transport engineering current density (Je), and results have reached 5500 A/cm2 at 77K and self-field. Stacked conductors are roll deformed prior to multifilament consolidation and multifilament stacks have reached 5600 A/cm2 at 77K and self field. These HTS composites have great potential for providing high Ic, Je, and reducing fabrication cost. An overview of this new processing route will be presented.
