Abstract
A method for fabricating transformers each having a core made from a lamination body of strips made of an amorphous magnetic alloy comprises the steps of forming a ring-like lamination body using a grindstone cutter and a gas coolant to obtain a developed lamination body, shaping the developed lamination into a substantially rectangular core, assembling windings with the core using a sliding tool for inserting leg portions of the core into windows of windings, covering the core with a core cover and mounting a grounding member so as to ground the core to the ground.
