  • Superconducting current lead
    Patent number: 6153825
    Abstract: A superconducting current lead includes a cylindrical support member 3, and superconducting wire material units 1 each of which is fixed onto the support member and each of which is composed of a single tape-like oxide superconducting wire material or a laminated tape-like oxide superconducting wire material, wherein tape surf aces of the superconducting wire material units are disposed in parallel with a circumferential direction in a cylindrical coordinate system, and the cylindrical support member is formed from a low thermal conductivity material.

  • Superconducting current lead
    Patent number: 6034588
    Abstract: A superconducting current lead is provided, in which a plurality of unit conductors serving as current paths and each formed from a tape-like oxide superconducting wire are disposed on a cylindrical support member 4 so that a tape surface of the superconducting wire material is made parallel with a circumferential direction in a cylindrical coordinate system, and magnetic members 3 are disposed between the plurality of unit conductors.
