Abstract: The nonlinear resistor includes a sintered varistor granulate filler embedded in a matrix. The granulate is mainly crystalline, spherical particles made of metal oxide, separated from each other by grain boundaries. The filler also includes geometrically anisotropic conductive particles which cover part of the surface of the spherical particles. Also, the varistor granulate may contain two fractions of particles of different sizes, one fraction being of greater diameter than the other, and arranged tightly so that particles of the second fraction fill the holes.
