    • The invention relates to a superconductive multi-phase, fluid-cooled cable system comprising a) a cable comprising at least three electrical conductors constituting at least two electrical phases and a zero- or neutral conductor, said electrical conductors being mutually electrically insulated from each other, 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. The invention further relates to a method of manufacturing a cable system and to its use. The object of the present invention is to provide a simplified manufacturing and installation scheme for a fluid cooled cable system. The problem is solved in that 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 expansion of the cable with respect to the thermal insulation. An advantage of having a non-concentric arrangement, e.g. in the form of a 'separate' cable comprising the conductors and a 'separate' tubular thermal insulation (e.g. a vacuum insulation tube) provided in multiple segments, is that these 'individual elements' may be produced in parallel and independently and joined in a simple way. The NON-concentric solution has a potential for being economically favourable, logistically (production wise, material wise, customer rating wise, i.e. in every sense flexible) flexible and for saving manufacturing time. The invention may e.g. be used for the low, medium and high-voltage superconductive DC- or AC-cables for power distribution.
