Abstract
A method of fabricating electrical core sheet assemblies such as transformer limbs, transformer yokes, and transformer cores, includes the steps of first cutting electrical core sheets, whose main surfaces have been provided with an anti-corrosion layer, into a desired shape. The side surfaces of the cut core sheets are first provided with an anti-corrosion layer, before the cut core sheets are assembled into the desired core sheet assembly.
