Abstract The essential conditions of high-temperature superconducting (HTS) wires are a high transport critical current density, shape uniformity of long length wire and mechanical performance. By exploiting the properties of (Bi, Pb) 2 Sr 2 Ca 2 Cu 3 O x (Bi-2223) HTS material, we have succeeded in semi-mass-producing long wire (in the kilometer-class), which can be drawn, by processing silver alloy sheathed multifilamentary wire into tape form. It is now developing Bi-2223 HTS wire with even higher performance in order to develop the superconducting equipment required for industrial applications at the earliest possible time. This paper presents the results of Bi-2223 HTS wires' performance by the powder-in-tube manufacturing technologies, which we developed. Typical J c performances for 10–1623 m long wires are above 30 kA/cm 2 (77 K, self-field, 1 μV /cm). Recently we have completed the production of total over 150 km Bi-2223 HTS wires necessary to HTS magnet for Si single crystal growth applications and 66 kV/1 kA, three phase, 100 m long HTS power cable.
