Certain windings in a transformer are subjected to radially inwardly-directed forces while being short-circuited. If such a winding is not sufficiently stable itself, particularly with respect to tape windings, or does not have sufficient support radially outwardly or inwardly, it will buckle or break. To prevent such an occurrence, it is possible to arrange an outward support around the winding by completely or partly filling up the space between the winding, which is subjected to buckling stress, and a second winding positioned outside the first winding. Additionally, there is required an inner supporting cylinder, which is preferably made of metal, so that it can be made relatively thin.
