Abstract
A transformer winding having a conductor wound in a plurality of turns is disclosed, wherein the transformer winding includes a reinforcing part arranged at a winding transition in a manner so that the reinforcing part covers more than 180 degrees of the conductor circumference, whereby the bending strength of the conductor at the location of the reinforcing part is increased. The resistibility of the transformer winding against bending stress is hence improved.
