Epoxy resins crosslinked with acid anhydride hardeners are widely used in high voltage insulation. They have excellent dielectric, electrical and mechanical properties up to relatively high temperatures. However, neat epoxy systems exhibit low thermal conductivity and unsuitable coefficient of thermal expansion (CTE) when used with metallic materials such as high voltage conductors.
