The current-carrying device (102) is adapted to extend in the axial direction of the outer shell. Along at least a part of the axial extension of the current-carrying device the outer shell extends axially with a space (118) between its inner periphery (114) and the current-carrying device (102).

    Abstract: The invention relates to a nonlinear field control tape containing ZnO microvaristor particles. The doped ZnO particles are produced by crushing a sintered ZnO block, by desagglomeration or crushing of calcinated granulated particles, or by crushing of a calcined or sintered tape (tape casting). Embodiments, among other things, relate to: hollow ZnO microvaristor particles produced by granulation technique, having reduced average density and having diameters in a range well below 90 µm; and compounding the ZnO filler in binders that are used to impregnate tapes. Compared to nonlinear field control tapes with conventional embedded nonlinear filler particles, a stronger and more reliable nonlinear resistivity is achieved and the ZnO filler is simpler to produce and to compound in the binder. The resulting tapes are flexible, preferably self-adhesive and have a strong nonlinear electrical resistivity. The tapes are useful to protect high field-stress regions in electrical components.

    Abstract: A method is disclosed for producing a non-linear powder having microvaristor particles which have a non-linear current-voltage characteristic. The production steps includes mixing non-metallic particles with the microvaristor particles, thermally treating the non-metallic particles for decomposing them into electrically conductive particles and fusing the electrically conductive particles onto the microvaristor particles. Embodiments, among other things, relate to: breaking up agglomerates of the non-metallic particles during mixing; keeping the decomposition temperature below a sintering or calcination temperature of the microvaristor particles; and choosing micron-sized or nano-sized non-conductive particles for microvaristor decoration. The production method produces varistor powder with improved reproducibility of the non-linear electric current-voltage characterstic and with reduced switching fields (Es).

    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.
