Abstract

The present invention relates to a transformer assembly (20), comprising: a cylindrical inner housing (21) and a cylindrical outer housing (26) partially surrounding the cylindrical inner housing (21), the cylindrical inner housing (21) and the cylindrical outer housing (26) forming an enclosure (30), wherein the enclosed volume of the enclosure (30) between the cylindrical inner housing (21) and the cylindrical outer housing (26) is filled with an insulating liquid; - at least one winding (22, 23) in the enclosed volume (30); and - a first cooling means arranged in or at an inner surface of the outer housing (26) to provide cooling for the at least one winding (22, 23).
