DEVICE FOR IMPREGNATING WINDING BAR INSULATION IN ELECTRICAL MACHINE Russian patent published in 2006 - IPC H02K15/12 

FIELD: impregnating winding bar insulation.

SUBSTANCE: proposed device has winding bar impregnation reservoir communicating with tank holding impregnating material. Impregnating reservoir is, essentially, vacuum-tight shell communicating with pipeline of vacuum-producing plant. Vacuum-tight and sealed shell functions as thermally shrinkable or flexible hose holding pressure impact. Reservoir can also function as mold built of several parts screwed together with intermediate packing installed over circumference.

EFFECT: improved penetration of impregnating material into insulation.
