A winding assembly for a transformer, in particular with a medium operating voltage of Um≥79.5 kV, wherein the winding assembly includes at least one winding, which ends in a winding conductor, where the winding conductor is connected to a switching line, which is configured to interconnect the winding to other windings, and where the connection of the switching line to the winding conductor is arranged inside the winding so as to reduce the danger of partial discharges and flashovers in the high-voltage end-line region for high-temperature applications.
