摘要： Arranging conductive windings (6) being impregnated with a filler, and for a large electric motor, in particular a turbogenerator, comprising a carrier body (1) having conductor windings, the latter being composed partly of bars winding (3) inserted in grooves (2), each winding shaft (3) having an arrangement of conductors (6) surrounded by an insulating layer (7). According to the invention, in each groove (2) of a winding arrangement conductors (6) according to the generic term, the formation of cracks due to thermal process of expansion and shrinkage is concentrated in predetermined zones electrically shielded , so that in any cracks there can be no excessive electric field strengths trigger discharges glow. This is achieved in that each winding shaft (3) is enveloped by a first semiconductor layer (8) and between each winding shaft (3) and each groove wall (11) is arranged least one second semiconductor layer (10) electrically connected to the first semiconductor layer (8) and a separating layer (9) decreasing the aggregation, due to the load which is impregnated with the layout, the first semiconductor layer (8) with the (at least) a second semiconductor layer (10).
