  • Magnet wire having differential build insulation
    Patent number: 6492892
    Abstract: A magnet wire having differential build insulation for use in transformer coils is disclosed. The wire has a rectangular conductor with an insulation that is thicker on the top and bottom surfaces of the wire than it is on the sides. With the thicker coating on the top and bottom, the wire can be used in layer wound distribution transformer coils, both high voltage wire wound coils and low voltage wound coils, without needing additional insulation between the layers of the winding.
