Abstract
Magnetic core structure for single-phase shell form transformers. The magnetic core structure includes an outer magnetic core formed of a plurality of spaced legs joined at their corresponding ends to common yokes. Inner magnetic cores are disposed between the legs of the outer magnetic core and spaced therefrom to form gaps completely therearound. Double-webbed beams are positioned underneath the magnetic core structure to support the structure from the transformer tank. Each web extends into the gap between a leg of the outer magnetic core and the adjacent leg of one of the inner magnetic cores.
