Abstract

An elementary capacitor of high energy density and high voltage, for energy accumulation, discharge, commutation or filtering purposes, comprises two layers A,B formed by a metallization 4,4 having a resistance per surface unit of between 2 and 30 ohm being applied on a fibrous support 5,5' and having at least one further dielectric 6, 7,6',7', two such layers forming the capacitor, which is impregnated with a liquid dielectric and is self-healing. The thickness and the nature of each dielectric as well as the liquid dielectric are so selected to ensure that when the rated voltage is applied, the ratio between the prevailing electric field strength and the disruptive strength is substantially equal for each of the dielectrics. When this capacitor is charged to its rated voltage, the average electric field strength prevailing in the dielectric is between about 200 V/ mu m and more than 400 V/ mu m, and the volumetric energy density is between about 0,5 J/cm<3> and more than 2 J/cm<3>. <IMAGE>
