Fixation structure of superconducting cable and fixation structure of superconducting cable line

摘要

A fixation structure for fixing a superconducting cable including a cable core and a thermal insulation tube. The fixation structure includes a fixation box connected to the thermal insulation tube, including a hollow thermal insulation structure, and through which the cable core is passed, a fixation body for fixing the cable core on the inner wall of the fixation box, and a diameter-expanded reinforcement layer 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.
