摘要
The long conductor fabrication is one of key technologies to realize the High-Tc superconducting power cable. A 50-m long conductor was fabricated by helically winding the High-Tc superconducting tape onto a former with a minding machine. The conductor consisted of ten layers of Ag-sheathed Bi-2223 tape which had a high critical current density of 10,000 A/cm(2) (at 77 K). AC losses and layer-by-layer current distribution were measured, feeding AC current of 100 to 2,000 Arms to the conductor cooled by LN2. The results showed that most of the current flowed in the outer layers where the impedance was low, and that AC losses were remarkably reduced by making the current distribution uniform.
