Multifilamentary superconducting Bi-2223 tapes made with a powder-in-tube process have been used to assemble multistrand, multilayer cable conductor prototypes. The electrical performance of these conductors has been evaluated at 77 K in self-field with DC and AC transport currents. Results show that these conductor prototypes, carrying up to 4,200 A DC, approach the 2,000 A AC operation threshold required for the commercial application of HTS power transmission cables. Combined with recent improvements in tape mechanical performance, stability, and long-length manufacturability, these results show the potential for use of HTS tapes in power transmission cables.< >
