Abstract:
1. A superconducting cable having a plurality of superconducting wires wound around a core material in a multilayered manner, wherein the superconducting wires include both a twisted filament type superconducting wire having spiral superconducting filaments and an untwisted filament type superconducting wire having straight superconducting filaments, wherein a conductor layer is formed with the superconducting wires wound around the core material in a multilayered manner, and at least the innermost layer of the conductor layer comprises an untwisted filament type superconducting wire, and at least the outermost layer of the conductor layer comprises a twisted filament type superconducting wire; and wherein a magnetic shielding layer is formed with the superconducting wires wound in a multilayered manner over an electrical insulation layer wound around the conductor layer, and at least the innermost layer of the magnetic shielding layer comprises a twisted filament type superconducting wire and at least the outermost layer of the magnetic shield layer comprises an untwisted filament type superconducting wire.
