ABSTRACT:
Conductor bar for electric machines operating at high voltage, including at least two subconductor packets being disposed side by side and being formed of mutually insulated subconductors, the subconductors being intertwined in such a manner that each subconductor occupies each possible physical position in at least one location within the conductor bar, an insulating sleeve, a semiconductor layer applied to the insulating sleeve, a further semiconductor layer disposed between the subconductor packets and the insulating sleeve, the conductor bar having a straight portion and narrow sides having a given width, a narrow-side subconductor bar crossing from one subconductor packet to another, the narrow-side subconductor bar being disposed at a given height filling a portion of the given width of the narrow side leaving a remaining width, hardenable cement layers being disposed substantially at the given height flanking the narrow-side conductor bar in vicinity of the crossing and filling the remaining width. The hardenable cement layers are extended over the entirety of the straight portion on each narrow side of the subconductor packets. Conducting strips disposed on the cement layers, the conducting strips and insulation of the insulated subconductors therebelow having holes formed therethrough, and conducting cement being filled into the holes.
