摘要：
A method of manufacturing transformer windings embedded in casting resin is disclosed which utilizes an integrated winding mandrel for producing a non-standard oval shaped epoxy encapsulated low voltage coil for dry type distribution transformers. The method includes a process of winding a low voltage coil of alternate layers of copper conductor (24) and insulating tape (26), over a disposable mold formed by wrapping steel sheet material over inner mold support plates (14), the formed mold acting as both a winding mandrel and as an inner mold (20) for epoxy encapsulation. Both the inner and outer molds are made of low cost sheet metal utilizing a 'wrap and band' process. The complete winding and molding processes can all be conducted utilizing a conventional square mandrel shaft (12) on a standard coil winding machine (10).
