Abstract: A composite is formed from at least one base material and at least one filler powder mixture dispersed in the base material. The filler powder mixture has a filler powder fraction and at least one further filler powder fraction. The filler powder fraction has an average powder particle diameter (D50) selected from the range from 1 ?m to 100 ?m and the total proportion of the filler powder mixture in the composite (degree of fill) is above 50% by weight. The further filler powder fraction has a further average powder particle diameter selected from the range from 1 nm to 50 nm and the proportion of the further filler powder fraction in the filler powder mixture is selected from the range from 0.1% by weight to 50% by weight. A high degree of fill can be achieved at a low viscosity in the presence of nanosize filler particles. The composite is particularly suitable as embedding composition (pourable resin system).

Abstract: A coupling electrode for capacitive voltage tapping within an insulating body of a component which has at least one conductor section which is embedded in the insulating body and to which a high-voltage potential can be applied, having an electrode section which is composed of a semiconductive plastic, and having a connecting element which is electrically connected to the electrode section and is designed such that it can be passed out of the insulating body. A holder which is composed of a non-conductive material and, is connected to the electrode section and has the positioning means, which allow isolated mounting of the electrode section.
