Superconducting cable fixing structure and superconducting cable line fixing structure

摘要

There is provided a fixation structure for fixing a superconducting cable 10 including a cable core 11 and a thermal insulation tube 12. The fixation structure includes a fixation box 21 connected to the thermal insulation tube, including a hollow thermal insulation structure, and through which the cable core is passed, a fixation body 23 for fixing the cable core on the inner wall of the fixation box, and a diameter-expanded reinforcement layer 201 that is an electrical insulation layer that has a diameter decreasing toward both ends and is formed on the cable core. A refrigerant flows through the inside of the inner wall of the fixation box. The cable core is fixed on the inner wall with the fixation body through the diameter-expanded reinforcement layer. The structure implements a simple and low-cost fixation structure appropriate for an electric field design.
