Abstract
Flexible, electrically insulating pipe connections are required for electrical machines with liquid-cooled rotor winding between the water distribution chambers, which are rigidly connected to the body of the rotor, and the water distribution headers in the coil end. A pipe connection is proposed whose section on the side of the distribution chamber is designed as an insulating link which projects at least partially into the wall of the water distribution chamber. The section on the side of the coil end is designed as a flexible link which can be shifted in axial direction relative to the insulating link or which is axially movable in itself.
