System having a superconductive cable

Abstract

A system is provided having a superconductive cable (KA) which consists of a superconductive inner conductor (1), a screen arranged concentrically therewith and a dielectric applied (3) between the inner conductor and the screen. The screen (S) is constructed from a superconductive part (4) and a part (5) consisting of an electrically highly conductive material enclosing the latter, and in which the screen is enclosed with the inclusion of an intermediate space (9), used for feeding a liquid refrigerant through, by a cryostat (KR) which consists of two stainless steel tubes (6, 7) extending concentrically with one another and separated from one another by an intermediate space (8). In order to protect against abrasion of metallic parts, the surface of the screen (S) of the cable (KA), which is enclosed by the cryostat (KR), and/or of the cryostat (KR) is provided all around on its inner surface with a liner layer (10) made of an abrasion-resistant material with a lower friction coefficient compared with steel, which, when it encloses the screen (S) of the cable (KA), is permeable for the refrigerant.
