Abstract

Various teachings of the present disclosure include a device for impregnating, consolidating, or electrically insulating a body bearing single-layer or multi-layer windings. In some embodiments, the device comprises: electrical contacts for applying a DC voltage between the windings and the body; a multi-component reactive resin; and a resin bath filled with the reactive resin. A DC voltage of at least 300 V/mm is applied between the windings and the body, with the result that the body bearing the windings, on the one hand, and the windings, on the other hand, act like the two electrodes of a capacitor and draw in the reactive resin.
