High TC superconducting cable conductor employing oxide superconductor |
摘要 |
Provided is an insulated oxide superconducting cable conductor having a high critical current and a high critical current density. The insulated oxide superconducting cable conductor comprises an elongated former, a plurality of tape-shaped multifilamentary oxide superconducting wires which are wound on the former at a bending strain factor of not more than 0.5%, and a spirally wound tape-shaped insulating material covering the tape-shaped multifilamentary oxide superconducting wires. The tape-shaped multifilamentary superconducting wires are superposed on the former in layers, whereby stabilizing materials of the superposed superconducting wires are in contact with each other. The tape-shaped insulating material consists essentially of a material which is contracted at a thermal contraction rate of at least three times that of the tape-shaped multifilamentary wires by cooling from a temperature of 298 K to that of 77 K. The tape-shaped insulating material can apply a pressure to the superposed multifilamentary superconducting wires toward the former while improving electrical contact between the superposed multifilamentary superconducting wires by cooling in employment. The former can be formed of a flexible tube.
