Abstract: The invention relates to a nonlinear electrical material with improved microvaristor filler (1'), to devices and electrical apparatuses comprising such nonlinear electrical material and to a production method thereof. According to invention, the filler (1') comprises larger spherical particles (5) and smaller irregular particles (6) that are arranged interstitially and provide non-point-like and/or multiple contact areas (56, 56a, 56b, 66) owing to their irregular outer shape comprising edges and faces. Embodiments, among other things, relate to: spherical particles (5) being calcinated and broken-up to retain their original shape; irregular, spikly shaped, particles (6) obtained by calcinating or sintering and crushing or fracturing granules or blocks; and addition of a third filler fraction. Advantages, among others, are: higher filler contents, more and more durable inter-particle contacts (56, 56a, 56b, 66), enlarged effective micro-contact area, and improved electrical performance of the nonlinear electrical material.

Abstract: Descargador de sobretensión con dos terminales de corriente estacionarios (2, 3) y con una resistencia eléctrica no lineal que contiene dos electrodos (6, 8) distanciados uno de otro en la dirección de un eje y un cuerpo de resistencia (7) constituido por una matriz y un material de relleno de forma de polvo con comportamiento de varistor incrustado en la matriz, caracterizado porque el cuerpo de resistencia (7) está formado por un material compuesto deformable en frío y se encuentra prensado entre los dos electrodos (6, 8), formando así la resistencia eléctrica no lineal.
