Air-cooled turbogenerators provide a modern, hi- ghly compact solution for: • base and peak load operation • daily startup and shutdown • easy low cost maintenance A range of models offering high efficiency, excel- lent quality and optimum reliability are available to meet turbine requirements. The reduced im- pact of auxiliary systems simplifies unit manage- ment and cuts the cost of spare parts. Design features and manufacture Ansaldo Energia air cooled generator technology is continuously upgraded and enhanced by dedi- cated R&D work and new design tools, including finite element 3D analysis...

The self-supporting stator core is assembled and welded to the lower part of the housing in such a way as to permit thermal expansion and core vibration without transmission to the foundation. The stator has a two-layer transposed bar winding insulated with class F mica paper on glass-fibre tape (resin rich insulation system). Bars are firmly braced in the slots by means of epoxy-glass slot wedges and a ripple spring to prevent loosening after long service. Rotor The rotor body is machined from a single alloy steel forging with excellent magnetic and mechanical properties. Forgings are purchased...
