Abstract

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.
