Abstract: A clamping ring and static plate used for axially compressing the ends of a cylindrically shaped power transformer winding. The electrically conductive static plate portion of the combination device is formed around and is insulated from a foundation providing, high-strength material, clamping ring. In addition to saving material and space, the use of two or more of these devices concentrically positioned, permits the application of unequal clamping forces to concentrically positioned windings; at least one of these devices having reduced insulation requirements.
