3-COAXIAL SUPERCONDUCTING POWER CABLE AND CABLE'S STRUCTURE

摘要

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.

1. A structure of a superconducting cable, in which a plurality of superconducting layers and a plurality of electricity insulating layers form a layer with respect to one axis, comprising:
each of the electricity insulating layers is disposed between adjacent superconducting layers, and in at least one superconducting layer other than an outermost layer among the plurality of superconducting layers, a space is formed between adjacent superconducting wires, and a wire having a critical current different from the supper conducting wires is disposed in the space.
