  • Method for producing a fully transposed high tc composite superconductor and a superconductor produced by said method
    Publication number: 20050227873
    Abstract: A fully transposed composite superconductor of the Roebel bar type is produced. The superconductor is formed from combines superconductors. The process step for forming the subconductors, which are being configured with a lateral projection into a region of a neighbouring subconductor, is separated from the stranding step. Carrier strips, which are coated with the superconductive material, are used as the conductors.

  • Switching device for superconducting technology
    Patent number: 6809618
    Abstract: A switching path having superconducting material in a switching device may be cooled to a predetermined superconducting operating temperature. The switching device includes a mechanism for exceeding at least one of the critical values of the superconducting material in a controlled manner to change the switching path from the superconducting state to the normally conductive state. The switching device may have an operating temperature of below 40 K, and contain magnesium diboride as the superconducting material for its switching path.
    Type: Grant
