A needle-plane electrode system was used to study the characteristics of the silicone rubber under AC corona. Microstructure and chemical structure change analysis on the surface of silicone rubber after corona ageing was made by using SEM, AFM and FTIR. Infrared spectrum shows that corona would cause the rupture of fundamental chain and branched chain of material. Along with the increase of corona...
This article introduces the research on composite insulator of various degrees by using Fourier transform infrared spectroscopy (FTIR). The results show there is a close relationship between absorption areas of the functional group of Si-CH3 and Si-O-Si of silicone rubber shed and housing aging. Along with the severity of ageing in the appearance of composite insulator, the absorption areas of the...
