Abstract

A winding system comprises at least one coil made of a winding conductor (104) comprising electrically conductive material and a tubular cooling channel (113) in the longitudinal direction of the winding conductor. At each end of the winding conductor, there is a coupling element (105) made of electrically conductive material. A first end (108) of the coupling element is hollow and attached to an end of the winding conductor so that the first end surrounds the end of the winding conductor. A second end (109) of the coupling element comprises an interface (110) to form a galvanic contact with an external electrical conductor. A middle portion of the coupling element comprises a channel (112) connected to the cooling channel of the winding conductor. Thus, the coupling element implements both an electrical connection and a cooling fluid connection, and all the electrically conductive material can be cooled by the cooling fluid.
