Abstract
A method is for impregnating a high voltage insulation of a winding bar (), the winding bar () having a conductive bar () around which layers of insulating mica tape defining said high voltage insulation are wrapped. The method includes enclosing the winding bar () in a flexible sleeve (), applying a vacuum in the flexible sleeve () to extract the gases contained in the insulating mica tape, supplying an impregnating resin into the flexible sleeve () to impregnate the mica tape (), and curing the resin. The impregnating resin is supplied into the flexible sleeve () at a pressure less than 1.5 bar.
