Abstract

The coil winding, e.g. a transformer coil (6), is inserted in an elastomer mould (4) of silicon, which has a cavity matched to the shape of the completely embedded coil winding. The mould (4) is then placed in a tub (8) which is filled with a flowable impregnation medium (9) until the coil winding is covered, and is then evacuated. The vacuum is maintained until the coil winding is completely impregnated, without blow-holes. Subsequently, the mould (4) with the coil winding is placed in an oven and is heated there to the curing temperature. After a curing period, the mould (4) is taken from the oven and the coil winding (6) is removed from it. The mould (4) is produced with the aid of a metal model. <IMAGE>
