Flexibility and a.c. characteristics of Bi-2223 Ag-sheathed multifilamentary superconducting wire (Ag-sheathed wire) were investigated for cable conductors. For the application of a power transmission cable, it is important to note the properties of the high Tc superconducting (HTSC) cable conductor. Several types of flexible conductors were fabricated by spiral winding on flexible mandrel. The bending property was investigated in a 1.4 m/3-layer conductor and a 5 m/8-layer conductor. The critical current Ic of the 5 m/8-layer conductor was measured under the bending strain of 1.3 m radius in liquid nitrogen. The conductor's Ic was 3000 A, and the Jc was 13,000 A/cm2. Using the 0.7 m conductor, we investigated the relation between the a.c. loss and the number of layer of the cable conductor.
