Abstract: The present work aims to present the results of an application of a bisphenolic epoxy resin (DGEBF) containing silica nanoparticles (RN) and compare its properties with a bisphenolic epoxy resin (DGEBA) (RE), currently used. In this context, prototype stator bars for hydrogenerators were manufactured, according to the VPI (Vacuum-Pressure.Impregnation) system and their electrical properties with the tests of dissipation factor and voltage endurance. Within the results for the resins it was observed that: (i) dissipation factor and voltage endurance are practically the same for both resins; (ii) the resulting values of tip-up were 0.014% for RE and 0.020% for RN resin and (iii) the estimating of the life-time is about 40 years, what is suitable for most industrial applications. In this sense it is suggested that the RN resin can be an alternative to the RE resin, with an equivalent electrical performance.
