IMPREGNATING RESIN SYSTEM FOR INSULATING MATERIALS IN SWITCHGEAR ASSEMBLIES

摘要

An insulating resin for switchgear assemblies based on glycidyl esters contains 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 it is highly tracking-resistant.
