We developed a 15 m-long, 2.6 kA-class conductor, which was made by winding a number of transposed segments around a stainless steel flexible former. The transposed segment consisted of five Bi-2223 tapes, which were strengthened with Ag-Mg-Sb sheath and insulated with resin individually. The conductor had a three-layer structure, which was taken by a method of equalizing impedance of each layer by adjusting spiral pitches. Current distribution in the same segments for the conductor was unified below changing rate of ±5%. Further, current distribution in three layers was homogenized below ±6% in the range from 200 to 2800 A. As the results, we successfully carried out a development of the low AC loss high- Tc superconducting cable, for which AC loss was 0.1 W/m at flowing 1000 A.
