摘要： A cryogenic cable termination connector having a small heat inflow from the outside and stable electrical insulation properties. The cryogenic cable termination connector includes a lead-out conductor led out from a site at a very low temperature to a site at room temperature via a liquid refrigerant layer, a refrigerant gas layer, and an oil layer. The lead-out conductor includes a capacitor-cone insulator in which plural metal foils for dividing an electric field from a high voltage level down to the ground voltage level are stacked through an insulator. Among electric field tilting portions in which voltage changes gradually from the high voltage level to the ground voltage level, an electric field tilting portion positioned at a lower part is located in the liquid refrigerant layer and an electric field tilting portion positioned at an upper part is located in the oil layer.

摘要： A terminal connecting part has: a low temperature container filled with a cooling medium; a conductor current lead which has one end immersed in the cooling medium and the other end led to a normal temperature part; and a conductor movable connecting terminal which electrically connects a superconductive conductor layer and the conductor current lead of a superconducting cable. The superconductive conductor layer of the superconducting cable stripped stepwise from a front end is connected to the conductor current lead through the conductor movable connecting terminal. The cable core of the superconducting cable is movable in a longitudinal direction and is rotatable in a circumferential direction while maintaining electrical connection between the superconductive conductor layer and the conductor current lead. The cable core is horizontally supported in the low temperature container.

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.
