Impregnation Systems for Electrical Engineering

System for the impregnation of electomagnetic coils, e.g. of electric motors, transformers, generators Impregnating in electricla engineering means applying an impregnating agent in gaseous or fluid form to a porous body in order to insulate it electrically, i.e. that reliable protection against electrical breakdown is provided even when the thickness of the insulating layer is small. For each application HÜBERS provides appropriate process. HÜBERS offers all relevant process variants including vacuum impregnation, vacuum-pressure impregnation and atmospheric impregnation and of these coupled with the use of the many different impregnating agents such as varnish, resin, oil, wax, gas etc. The processes of evacuating the parts prior to impregnation and if necessary of vacuum-drying the impregnated parts are matched to the properties of the parts and ensure that the agent wets the walls of the pores properly and fills the cavities completely.
