For size reduction of gas insulated switchgears (GIS), application of permittivity‐graded material to insulating spacer has been studied. The electric‐field‐enhancement close to the lamination interface of the permittivity‐graded material obtained by laminating epoxy composites with different permittivities was investigated. The FEM simulation revealed that the increase of the layer number of the permittivity‐graded material could reduce the field enhancement close by the lamination interface, even when considering electric field distortion near the individual high‐permittivity particles filled in each layer.
