| Zusammenfassung: | A creepage block for a turbine rotor slot in which coil windings are embedded, wherein the creepage block is sandwiched between the windings and a wedge block, and wherein aligned radial cooling passages are formed in axially spaced locations in the windings and the wedge block. The creepage block includes a pair of solid half blocks in substantially parallel relationship, the blocks held in laterally spaced relation by a plurality of discrete spacers which may be dowel pins. |
