Abstract: A holding device for fastening a cast resin transformer winding relative to a transformer core has a support element and a receiving element attached to a tie rod. By fastening the support element to the receiving element attached to the tie rod, a cast resin transformer winding can be fixed rigidly and precisely centered relative to a transformer core. By attaching the receiving element directly on the tie rod, circulation in the lower region of the cast resin transformer winding or of an insulating cylinder also attached to the support element is ensured and thereby the thermal properties of a cast resin transformer winding produced in this way are improved. Furthermore a modular and thus simple design of the cast resin transformer is possible due to the possibility of connecting the receiving element to the tie rod by way of the support element.

Abstract: An electrical winding can be arranged concentrically around a magnet core. A novel transformer includes at least one magnet core and at least one electrical winding, wherein the electrical winding can be arranged concentrically around the magnet core. The electrical windings are connected fixedly to a fixing apparatus, wherein the fixing apparatus can be fixed in a radial plane. As a result, subsequent fixing of the electrical windings in relation to one another and in relation to the magnet core which is to be reinforced mechanically is dispensed with.
