The invention relates to an insulating resin for switchgear assemblies based on glycidyl esters, comprising nadic methyl anhydride/hydrogenated nadic methyl anhydride as a curing agent and an N-substituted imidazole as an accelerator. The resin has a substantially increased glass transition temperature with simultaneously high- quality mechanical characteristics and is very tracking-resistant.
L'invention concerne une résine d'isolation destinée à des installations électriques, à base d'ester de glycidyle, contenant de l'anhydride méthyl-nadique/anhydride méthyl-nadique hydrogéné en tant que durcisseur, et un imidazole à substitution N en tant qu'accélérateur. La résine présente une température de transition vitreuse sensiblement supérieure et un haut niveau mécanique, ainsi qu'une très bonne résistance au cheminement.
