Abstract:
1. Superconductive arrangement comprising: at least one superconductive cable having a superconductive material; and a first cryostat surrounding the superconductive cable for conducting a first cooling agent therethrough, said first cryostat being composed of at least one thermally insulated pipe which encloses a hollow space over its entire length in which the superconductive cable is arranged and through which the first cooling agent is conducted during operation of the arrangement, wherein magnesium diboride is used as said superconductive material, wherein a liquid or gaseous cooling agent cooled to a temperature of 39K or lower is used as the first cooling agent, and wherein a second cryostat is arranged coaxially around the first cryostat, and at a distance from the first cryostat, wherein the second cryostat is composed of two pipes arranged coaxially to each other and at a distance from each other, and wherein the pipes enclose a thermal insulation therebetween and through which during operation of the arrangement a liquefied gas, having a temperature of 112K or less, is conducted and wherein a high voltage proof insulation is arranged in the intermediate space between the first cryostat and the second cryostat, which completely encloses the first cryostat and abuts to the thermally insulated pipe of said first cryostat and the liquid nitrogen flows around and impregnates this high voltage proof insulation during operation of the arrangement, causing significantly improved dielectric values.
