Abstract
Class-F and class-B insulating materials based on the resin rich type mica-epoxy composites for the stator windings in large turbine generators have been developed by DHIC. In recent, stator winding bars applied with prototype insulation tapes and commercially available resin rich groundwall tapes were produced through the same manufacturing processes as the real bars. Comparative tests to obtain the insulation properties of both bars were carried out such as IR/PI. dissipation factor and partial discharge at room temperature. In this paper, the manufacturing processes and the insulation properties of the bars which were not aged are presented.
