  • Molded transformer with grounded electrically conductive layer
    Patent number: 4540967
    Abstract: This invention relates to a molded transformer whose windings are cast-insulated with a cast resin, and consists in disposing an electrically conductive layer within the resin insulation of the winding and grounding the conductive layer, thereby to enhance a withstand voltage with the dimensions of the air gap between the windings reduced and with a winding supporting spacer omitted.

  • Method of manufacturing a molded coil
    Patent number: 4457792
    Abstract: A method of manufacturing a molded coil for use in an electric apparatus such as a molded transformer or a reactor. The method includes the steps of covering a winding with an insulating prepreg, curing the prepreg under heat, and casting a synthetic resin around the prepreg. The method makes it possible to minimize any thermal stress that may develop in the molded resin layer.
