Development of Bi(2223) multifilamentary tapes with low alternating-current losses.

Author(s) : HUANG Y. B., WITZ G., et al., DHALLE M.

Summary

A significant reduction of ac losses in twisted Bi(2223) multifilamentary tapes with Ag sheaths has been achieved by using oxide (BaZrO3 and SrZrO3) barriers between filaments. These barriers have two important effects: they increase the transverse resistivity, which suppresses induced coupling currents, and they reduce filament bridging, which in pure Ag sheath tapes largely cancels the beneficial effect of filament twisting.
