Abstract:
1. A fixation structure of a superconducting cable comprising a cable core which comprises a former and a superconductor layer, and a thermal insulation tube housing the cable core and having a thermal insulation structure configured of an internal tube and an external tube, the fixation structure comprising: a fixation box connected to the thermal insulation tube, having a thermal insulation structure configured of an inner wall and an outer wall, through which the cable core penetrates; a fixation body for fixing the cable core on the inner wall of the fixation box; and a diameter-expanded reinforcement layer, the diameter-expanded reinforcement layer being electrically insulating, being formed on the cable core and having a diameter decreasing toward both ends, wherein an entire length of the diameter-expanded reinforcement layer is formed on the cable core; wherein a refrigerant can flow through an inside of the inner wall of the fixation box, and the cable core is fixed on the inner wall with a fixation body through the diameter-expanded reinforcement layer.
