A superconductive cable including: a former; one or more superconductive conductor layers provided outside the former; an insulating layer configured to surround the superconductive conductor layers; and one or more superconductive shield layers provided on an exterior of the insulating layer. The superconductive conductor layers and the superconductive shield layers are formed of superconductive wire rods, and each superconductive wire rod includes a metal substrate layer and a plurality of superconducting layers deposited on the metal substrate layer using a superconductive material. In the superconductive wire rods of an outermost superconductive conductor layer among the superconductive conductor layers and an innermost superconductive shield layer among the superconductive shield layers, each of the metal substrate layers and the superconducting layers are disposed in opposite directions.

Superconductive cable

The present invention relates to a cryogenic cooling apparatus capable of stably maintaining a cryogenic condition by repairing or exchanging a sensor such as a temperature sensor of the cryogenic cooling apparatus without releasing vacuum states of the cryogenic cooling apparatus and a system connected thereto, when the sensor needs to be repaired or exchanged.

Cryogenic cooling apparatus and connecting structure for superconducting device

A superconducting wire having improved electrical and physical properties.

Superconducting wire

A superconducting synchronous motor having a simple and stable structure is provided. The superconducting synchronous motor according to one embodiment of the present invention comprises: a rotary shaft; a rotation core mounted at the rotary shaft so as to be rotated by connecting with the rotary shaft; and hooked magnetic poles extending from one end of the rotation core in a longitudinal direction. Each of the hooked magnetic poles is composed of first and second inductors of a magnetic material alternately engaged with each other and a superconducting wire to be wound, and comprises a first superconducting field winding and a second superconducting field winding fixed closely at the other end of a first inductor rotation core and the other end of a second inductor rotation core, respectively. Each of the first superconducting field winding and the second superconducting field winding excites the first inductor and the second inductor to different poles.
