Abstract :
Epoxy molding resins are widely used for outdoor insulators in heavy apparatuses, especially for transformers in distribution equipment, bushings in traffic equipment, current and potential transformers, etc. Liquid type epoxy resins are used instead of solid type resin because of their easy treatment. This report investigates several properties of liquid type epoxy moldings and estimates their life in heavy apparatuses for long-term outdoor use
