Abstract :
Fuji Electric has recently introduced a vacuum pressure impregnation (VPI) system for air-cooled turbine generator stator windings in the 30~260MVA class. To accompany this, we have also developed a new insulation system for this VPI system, called the F-resin/GII insulation system. This insulation system is equipped with characteristics for operation over a long period of time and excellent heat cycle resistance. In this article, an evaluation of the mechanical characteristics of the main insulation for the new VPI insulation system is described
