“…It should be noted that the bismuth-based superconducting tapes have become popular for power applications at around 77 K in rather low magnetic fields such as power transmission cables, current limiters and power transformers. Typically, we carried out trials with 5 m and 50 m long 2 kA conductors assembled by winding the tapes in layers around formers; the former underwent voltage withstanding and current flow tests [1,2]. However, for adaptation to practical requirements, understanding of the complex physical properties of the oxide superconductors and its complex fabrication process is more significant, and enhancements of critical current density, uniformity in length, AC losses, mechanical strength, flexibility and current-carrying capacity were developed individually and in combination.…”

Some long-length Bi(Pb)-2223 tapes produced using the PIT technique and multilayered structure technique have been developed for an industrial material for which the requirement is the class at 77.3 K in long-length wires. For this purpose, we have achieved recent progress in performance, such as reproducibility of the class at 77.3 K and low magnetic fields for long-length tapes having sound filaments, overall critical current density of in a low silver:superconductor ratio tape, allowable strength of more than 100 MPa using silver alloy sheath and low AC loss of less than in kA class conductors using twisted wires.
