摘要： 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.

摘要： A transformer with a toroidal magnetic core. The toroidal magnetic core is housed in an insulating case. The insulating case has a top and bottom annular winding frames. These frames provide radial winding conductor grooves. The top annular winding frame provides a plurality of grooves for guiding an inter-connecting conductor therein each of which is formed between two adjacent winding conductor grooves. The inter-connecting conductor is guided through said guiding groove to connect between the adjacent two unit coils.
