Abstract
A method of making a transformer having an amorphous metal core uses resin coated substrate to reduce amorphous metal contaminants in the transformer coolant. The face of an annealed wound amorphous metal core is covered with a resin coated substrate. The core and resin coated substrate are bonded by pressing the core face. The second face is then done in the same way. The resulting resin coated substrate and transformer core is a unit. The substrate prevents amorphous metal pieces from escaping into the transformer oil and becomes a structural member of the core.
