<span>This paper is about preparation of silicone rubber (SiR) samples with different filler for high-voltage insulation purpose. The fillers used were silica from waste glass, calcium carbonate from cockle shell, silica/calcium carbonate and wollastonite. All the fillers were crushed into powder and undergo internal mixer and hot press as a material preparation. It was expected that the combination of filler with silicone rubber would give better result when experiencing ageing process. The direct current (DC) inclined plane test was used to investigate the tracking and erosion on silicone rubber composites. The tracking length was observed between the top and bottom electrode. Comparison would then be made between the silicone rubbers with different fillers based on the result obtained from the experiment.</span>

Abstract The present study deals with the fabrication of epoxy composites reinforced with synthesized nano-zirconia, and to study their properties for high-voltage applications. The epoxy composites were extensively characterized to understand the morphology, mechanical, thermal, and electrical insulating behavior. The surface morphology and molecular structure of the nanoparticle and its interaction with the base matrix ware investigated by scanning electron microscopy, Fourier-transform infrared spectroscopy, and X-ray diffraction (XRD). XRD profiles confirmed that particles were crystalline and nanosized. Moreover, the tensile characteristics were analyzed using various theoretical models that predict the stiffness of these composites. The glass transition temperature of the epoxy/ZrO2 composite increased with the increase in nanofiller content. The AC breakdown voltage reached a maximum of 14.8 kV for 2 wt% ZrO2 composite. The prepared composites have the potential to act as high-performance insulation materials.
