摘要： In a transformer or a reactor having at least one winding of foil-formed electrical conductor material, a magnetic-flux-controlling spirally-wound sheet of highly permeable ferro-magnetic material is arranged axially outside each end of the winding. The ends of the sheet are galvanically connected to the foil winding. By division of the magnetic material in the sheet, a high resistance in the longitudinal direction of the sheet, and thus lower losses, are obtained.
