FORMULATION FOR AN INSULATION SYSTEM, INSULATION SYSTEM THEREFROM AND ELECTRIC MACHINE HAVING INSULATION SYSTEM

摘要

The invention relates to a novel formulation, more particularly one that can be used to produce an insulation system by means of anhydride-free curing. The invention also relates to the production of an insulation system by means of the vacuum pressure impregnation (VPI) process with a dip bath for impregnating mica-tape-insulated stators of electric machines such as motors and generators. As a result of the invention, a sufficient gel time for processing in the VPI process has been achieved for the first time in anhydride-free impregnation resin in the VPI process with low content of zinc compound and/or superacid salt as accelerator in the solid insulation substance and optionally superacid salt in liquid impregnation resin.
