In order to improve the mechanical and thermal properties of the epoxy resin, high mass fraction of micro-alumina has been applied in the epoxy resin which is also considered to be a kind of extender in manufacture. However, the introduction of alumina fillers may cause deterioration of the electric property. In this paper, epoxy with different amounts of the micro alumina fillers ranging from 0 to...
GIS spacer plays an important role in the bus of the gas insulated switchgear in UHV substation. However, partial discharge and flashover may take place on the surface of the GIS spacer which may cause severe damage to the stability and safety of the whole system in long-term operation.
