The latent fault diagnosis of GIS equipment relies on the electrothermal corrosion information of the decomposition products of SF6. The thermal decomposition of epoxy resin under atmosphere (SF6-Epoxy) is essential to reveal the relationship between carbon-based characteristic decomposition components and the degradation of insulating materials. The thermal decomposition process of SF6-Epoxy was measured using synchronous thermogravimetry(TG)/differential scanning calorimetry(DSC), which unveiled the three pyrolysis stages of temperature range and heat release. The online gas chromatography identified nine decomposition components containing carbon, sulfur and oxygen elements. According to the panoramic pyrolysis reaction mechanism of the SF6-epoxy system, CO2, CH4, SOF2, H2S and H2 were proposed as the characteristic decomposition components for the thermal deterioration of SF6-Epoxy insulating system.
