摘要:
In order to obtain a highly versatile superconducting cable capable of absorbing differences in thermal contraction amounts that arise between three members, these being a cable core, an inner tube, and an outer tube, and to obtain a superconducting cable manufacturing method of the same, a superconducting cable includes a thermal insulation vacuum tube and a cable core. The thermal insulation vacuum tube includes an inner tube fixed at both ends and having a cooling medium filled inside, and an outer tube disposed at an outer peripheral side of the inner tube with a space between the outer tube and the inner tube maintained at a vacuum, and is configured to include a winding section wound with one or more turns. The cable core is fixed at both ends and disposed inside the inner tube.

A superconducting wire rod connection structure can comprise first and second superconducting wire rods, wherein the first and second superconducting wire rods are formed by layering a base material, an intermediate layer, and a superconducting conductor layer. The base materials of the first and second superconducting wire rods can be joined to each other, and the superconducting conductor layers of the first and second superconducting wire rods can be connected by a connection wire rod including a superconducting conductor layer. Further, the superconducting wire rod connection structure can comprise a separating portion in which connection ends of the first and second superconducting wire rods with the base materials joined to each other are separated from the connection wire rod.

A connection structure is provided for a pair of superconducting cables each including a cable core including a former and a superconductive conductor layer composed of a plurality of superconducting wires arranged along an outer circumference of the former. The superconducting wire has a laminated structure including a base plate and a superconducting layer formed on a side closer to one of principal surfaces of the base plate. One of the superconducting cables and another of the superconducting cables are connected with each other by a first superconducting wire and a second superconducting wire such that the superconducting layers of the first superconducting wire and the second superconducting wire face each other.

A transportation pipe includes a main-body vacuum insulated pipe, a central pipe, and a connecting vacuum insulated pipe. The main-body vacuum insulated pipe including a double pipe structure includes a vacuum part in a region between an inner pipe and an outer pipe. The central pipe through which a fluid to be transported flows, is arranged in the main-body vacuum insulated pipe. The connecting vacuum insulated pipe having a double pipe structure includes a vacuum part in a region between an inner pipe and an outer pipe. In a state in which two main-body vacuum insulated pipes are inserted into the connecting vacuum insulated pipe from respective ends of the connecting vacuum insulated pipe, ends of the main-body vacuum insulated pipes are away from one another, and the main-body vacuum insulated pipes are connected to one another via the connecting vacuum insulated pipe.
