An electric insulation device, including a chamber and an electrically insulating element formed by a cast polymer solidified into an elastic state inside the chamber. The electrically insulating element includes a plurality of particles of a ceramic that has a higher thermal conductivity than the one of the polymer.

Electric insulation device and an electric device provided therewith

An electric insulation arrangement including a field grading material including a matrix including a dielectric material. A plurality of micro varistor particles is distributed in the matrix. A plurality of bridge particles include an electrically conducting material and form electrically conducting bridges between individual micro varistor particles. The bridge particles form a percolating network together with the micro particles but do not form a percolating network by interconnection between themselves.
