  • Vacuum Pressure Impregnation and Process

    The Vacuum Pressure Impregnation (VPI) Process The VPI process is a significant technological advancement over the traditional “dip in varnish and then bake” approach used to insulate electric motors. In place of standard insulating varnish for electric motors, a special VPI epoxy insulation is used on the coils.
