    Abstract: Performance degradation of insulating parts of the 40.5 kV switch cabinet has been a severe problem because of the influence of the external operating environment and the power grid load. This paper applied the power frequency test and the partial discharge test on the 40.5 kV contact boxes at various times and studied many factors that could impact the performance of the insulting part, such as the ratio of insulating materials and environmental moisture absorption. It summarizes the main influencing factors of the performance degradation of the insulating part by employing analysis methods, such as IR test and TGA test.
    Key words: 40.5 kV switch cabinet; insulating part; epoxy resin; partial discharge
