11 VPI systems for all insulation processes Vacuum Pressure Impregnation (VPI) process steps! Drying the winding! Flooding with the impregnating system under vacuum! Impregnating under pressure! Draining the resin and removing the system to a storage tank! Gelling and curing 11

12 VPI systems for all insulation processes VPI vs prepreg Depending on the size of the machine and the size of the impregnating plant the choice will be between either single bar or global impregnation. The majority of manufacturers have switched to Vacuum Pressure Impregnation, because VPI offers some advantages in mechanical and electrical properties compared to the prepreg method. For example with global impregnation, in addition to the lower risk of voids, much better fixation of the coils and especially the end windings is possible. 12
