Patent ID: 8326386

Claim:
A superconductive multi-phase, fluid-cooled cable system comprising a) a cable comprising at least three electrical conductors constituting at least two electrical phase conductors and a neutral conductor, said electrical conductors being mutually electrically insulated from each other, at least two of said electrical conductors being concentrically arranged around each other separated by an electrical insulation, said zero- or neutral conductor forming a common electrical return conductor, said cable system comprising a common electrical screen surrounding said electrical phase conductors and being electrically insulated there from and b) a thermal insulation defining a central longitudinal axis and having an inner surface and surrounding the cable, said inner surface of said thermal insulation forming the radial limitation of a cooling chamber for holding a cooling fluid for cooling said electrical conductors, wherein said cable—at least over a part of its length—is located eccentrically relative to said central longitudinal axis when viewed in a cross section perpendicular to said longitudinal axis and where the eccentric location has the function of accommodating thermal shrinkage and/or expansion of the cable with respect to the thermal insulation.
