  • Electric insulation device and an electric device provided therewith
    Patent number: 8637773
    Abstract: 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.
    Type: Grant
    Filed: March 19, 2010
    Date of Patent: January 28, 2014
    Assignee: ABB Research Ltd.
    Inventors: Erik Jonsson, Lars Palmqvist, Ruslan Papazyan, Henrik Hillborg, Claire Pitois
  • Electric insulation arrangement
    Patent number: 8164413
    Abstract: 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.
