Abstract:
A water-cooled rotor for a large turbine generator in which the rotor passages are protected against corrosion by liners of stainless steel or other corrosion resistant material. In order to reduce the stresses in the liners due to differential thermal expansion, the liners are prestressed in tension against a concentric outer tube.
Abstract:
A transposed stranded conductor for dynamoelectric machines having four stacks of strands transposed in the slot portion of the conductor in such a manner that each stack moves to different transverse positions in successive longitudinal sections of the bar such that the stacks are reversed in transverse position at opposite ends of the bar. Preferably, the strands are also transposed in a manner to cause inversion of the relative strand positions at opposite ends of the slot so that the conductor is fully transposed with inversion of strand position both transversely of the slot and depthwise of the slot.
