<P>PROBLEM TO BE SOLVED: To provide a simple configuration including a superconductive electrical DC cable system, indicating at least one DC transmission element, and a cryostat suitable for introducing the cooling medium. <P>SOLUTION: The configuration comprises: a superconductive electrical DC cable system indicating a DC transmission element (4) consisting of two phase conductors insulated from each other; and a cryostat in which the DC cable system is disposed. The cryostat consists of at least one heat insulating metal tube surrounded by a circular closed layer. Both phase conductors (5, 6) consist, respectively, of a plurality of superconducting elements (9) collected as one unit. One separation layer (7) composed of an insulating material is attached between both phase conductors (5, 6), which are surrounded by a cover (8) made of an insulating material so as to form the DC transmission element (4) including the separation layer (7). <P>COPYRIGHT: (C)2013,JPO&INPIT |
