Abstract
The invention comprises a process for impregnating components with polymerizable impregnants which are liquid at room temperature or can be liquefied by heating and are cured by combined use of heat and high-energy radiation, wherein the components are impregnated at ambient temperature or in a preheated state and, after impregnation, are heated in the impregnant until partial gelation occurs, are treated with high-energy radiation before full curing and are then fully cured by thermal means.
Claims14
A process for impregnating a component having at least one electrically conductive winding, said process comprising
- providing one or more polymerizable impregnants which are liquid at room temperature or can be liquefied by heating,
- impregnating the component with the one or more polymerizable impregnants at ambient temperature or in a preheated state and, after impregnation,
- heating the impregnated component in the impregnant until partial gelation by partial curing occurs in the immediate vicinity of the winding,
- treating the impregnated component with high energy radiation before full curing to seal the surface of the component, and then heating the treated impregnated component to fully cure the impregnated component.
