An alternative method for fabricating a conductor bar (1,11) with a vacuum pressure resin-rich process (VPRP), especially for assembly into electric machines, is disclosed. It includes a method for producing a conductor bar (1,11) comprising the steps of -packing a conductive bar with a B-stage resin-rich main wall insulation (3) into a layer of release tape (5), a layer of breather/ bleeder (15) and thereon a layer of synthetic material (20) which is forming a hermetical sealing around the insulated conductive bar (1,11), -placing the insulated conductive bar (1,11) including above described layers into a vessel whereby the volume inside the synthetic layer (20) is connected to a vacuum pump, -evacuating the volume inside the synthetic layer (20) while an overpressure is created inside the vessel with a heated compression gas causing consolidation and thermal curing of the resin-rich insulation (3). |
