  • For the fabrication of HTS power cable, multifilamentary Bi-2223/Ag tapes have been prepared using the powder-in-tube (PIT) process. After final heat treatment, these tapes have $I_{c}$ value of 43A, and$ J_{c}$ value of $28,000A/\textrm{cm}^2$(77K, 0T). Prototype 1000A class multistrand conductor(length~1m) was fabricated using these tapes(length~300m). This multistrand conductor was impregnated with low-temperature epoxy. The transportation properties of prototype 1000A class multistrand conductor has been evaluated at 77K, and yielding a current capacity up to 1200A.A.A.

  • 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.
