Abstract

The insulation parts are the weak link in the 6.3～40.5 kV dry air switch cabinet

among which the epoxy resin insulation parts are widely used in the switchgear equipment

and the characteristic of the epoxy resin insulation parts directly determine the insulation performance and operation reliability of the switchgear.Epoxy insulation parts are generally made of bisphenol A epoxy resin and curing agent through complex chemical reaction.Different preparation conditions and processes have great influence on the performance of insulation parts.Based on the experimental analysis and research of epoxy resin samples with different ratio

the effects of glass transition temperature

packing and electrical scratch resistance on the flame retardancy of insulating parts are obtained in this paper.The results have certain guiding significance to the processing and manufacturing of insulation parts.
