摘要： A phase split structure of a superconducting cable includes three cable cores each having a shield layer provided around a superconductor, a splitter box housing the three cable cores extending from an assembly portion where the three cable cores are assembled into the cable, in a state in which the cable cores are spaced apart from each other, and an electrically-conductive connecting portion connecting respective shield layers of the cable cores to each other within the splitter box. In this way, occurrence of a large magnetic field outside the cable cores can effectively be reduced.

摘要： A phase split structure of a superconducting cable includes three cable cores each having a shield layer provided around a superconductor, a splitter box housing the three cable cores extending from an assembly portion where the three cable cores are assembled into the cable, in a state in which the cable cores are spaced apart from each other, and a shield connecting portion connecting respective shield layers of the cable cores to each other within the splitter box. The shield connecting portion allows the cable cores to have their respective shield layers connected together with low resistance and each shield layer can pass a current substantially equal in magnitude to that which each superconductor passes. Thus in each shield layer a magnetic field can be formed having a level that can cancel a magnetic field generated from each superconductor. The structure can thus effectively prevent a large magnetic field external to the cable core.

摘要： A superconducting cable has a plurality of superconducting wires wound around a core material (former) in a multilayered manner. The superconducting wires employ a twisted filament type superconducting wire having spiral superconducting filaments and an untwisted filament type superconducting wire having straight superconducting filaments. The layer in which an applied magnetic field is large and of which the low loss effect is expected is formed of twisted filament type superconducting wires, and the other layers are formed using the untwisted filament type superconducting wires; thus the AC loss can be reduced effectively. Thus, in the superconducting cable, the AC loss can be effectively reduced while a degradation of the current characteristics and the increase of cost are suppressed.
