Abstract:
1. A stator bar of a dynamoelectric machine, the stator bar having an outer groundwall insulation surrounding a perimeter thereof and extending along a longitudinal length thereof, the outer groundwall insulation comprising: at least one extruded member comprising an electrical insulation layer and an opposing pair of edges parallel to the longitudinal length of the stator bar, the edges being attached together along the seam so that the perimeter of the stator bar is entirely enclosed by the at least one extruded member, the opposing pair of edges abutting each other to define a seam that is substantially parallel to the longitudinal length of the stator bar, the opposing pair of edges comprising complementary interlocking features that physically secure the edges together, each of the interlocking features being continuous along a corresponding one of the edges so as to be substantially parallel to the longitudinal length of the stator bar.
