  • Composite conductor, superconductive apparatus system, and composite conductor manufacturing method
    Publication number: 20060021788
    Abstract: To provide a composite conductor suitable as a connecting conductor capable of reducing generation of Joule heat in a joint part between a conductor on a system side and a conductor on a power-supply side, while using a superconductor with less thermal invasion to a superconductive apparatus system. A composite conductor 10 comprises a superconductor 12 provided continuously in the flowing direction of the electric current, and a metal conductor 11 joined with the superconductor 12 and provided at least at a joint part with mating conductors 50, 60 to be joined, wherein the electric current is fed and received between the metal conductor 11 and the mating conductors 50, 60 by joining the metal conductor 11 and the mating conductors 50, 60, and wherein the superconductor 12 is arranged in the metal conductor 11 so as to be approximately parallel to the joint surface (joint interface) between the metal conductor 11 and the mating conductors 50, 60.
