Abstract

The superconducting Bi ₂Sr ₂Ca ₂Cu ₃O _y Bi-2223 tapes made with a powder-in-tube process laminated with a copper alloy have been used to design and develop a 5 m long multilayer concentric cable to be applied in railway systems. The electrical performance of the conductor has been evaluated with DC transport current at an economical 77 K (liquid nitrogen temperature) in the self-field. The inner and outer sheet wires were able to sustain electric currents of 10 130 A and 10 910 A, respectively. These values are sufficient for several types of commercial applications. The current values are significantly higher than the earlier reported ones in Bi-2223 or YBa ₂Cu ₃O _y Y-123 superconducting cables, indicating that the tape quality has considerably improved.
