Gas insulated switchgear (GIS) is used widely in high voltage substations. Existing formulations combine an epoxy resin with a micro-alumina filler, the filler provides good thermal conductivity, good chemical stability and excellent dielectric properties. The first area of the project involves modifying these existing formulations by introducing controlled amount of nano-alumina in an attempt to improve both the thermal conductivity and dielectric properties. A second facet of the project aims to explore alternative formulations where the alumina is replaced with silica (a much cheaper materials), thus providing lower cost GIS components suitable for less demanding applications.
