  • 3-coaxial superconducting power cable and cable's structure
    Patent number: 9012780
    Abstract: Provided are a three-phase coaxial superconducting power cable and a structure thereof. A certain space is formed between adjacent superconducting wires of a superconducting layer (disposed at an outer portion) having more superconducting wires among a plurality of superconducting layers, and another wire is disposed in the space, or the superconducting wires of the respective superconducting layers are disposed to have different critical currents. Accordingly, a waste of superconducting wires is prevented, and the optimized three-phase coaxial superconducting power cable is provided.
    Type: Grant
    Filed: July 11, 2013
    Date of Patent: April 21, 2015
    Assignee: UIDUK University—Academic Coorportion Foundation
