Imprex VPI System
Service Description
VPI stands for Vacuum Pressure Impregnation – an insulating method whereby a new winding is preheated, placed in a vessel and put under vacuum to remove air and moisture. Resin is then allowed to cover the windings, (still under a vacuum) forcing trapped air bubbles to expand and pop. Finally, pressure is placed over the resin to reduce the size of any bubbles that escaped the first two steps. This method will “wet” the entire winding surface with insulating varnish thus eliminating voids to insure corona free motor operation. This method is commonly used on form-wound coils and very large random windings
