Abstract :
A degradation of silicone rubber for polymer insulator housing by ultraviolet radiation was studied. The following techniques were used to investigate surface degradation of silicone rubber: Measurement of Contact Angle; Energy Dispersive X-ray (EDX) Analysis; Fourier Transform Infra-Red (FT-IR) Spectroscopy; Scanning Electron Microscope (SEM) Observation. It was found from the investigation that chemical composition near the surface was changed significantly and that hydrophobicity was reduced under severe ultraviolet radiation
