Abstract
A superconductive cable includes a superconductive conductor (), a dielectric () enclosing the latter and a superconductive screen () arranged over the dielectric acting as a spacer. The cable is enclosed with the inclusion of an air gap by a cryostat () which consists of a metal inner tube (), a metal outer tube () and super insulation () arranged between them. An intermediate metal tube (), which is closed all around over its entire length, is arranged over the screen () while leaving a gap () from the cryostat (). A medium which is fluid at room temperature, and to which a constant pressure is applied, is introduced as an impregnating medium for the dielectric () into the space between the conductor () and the intermediate tube (), and at least one refrigeration unit for supplying a liquid refrigerant is connected to the gap () between the cryostat () and the intermediate tube ().
