A process for producing an electrical device with a Umhüllmasse

A method for manufacturing an electric device (10) to an electrical component (12), which having a cement mass (22) Umhullmasse (20) at least partially wrapped is presented. The method comprises the steps of: - providing the cement composition (22); - mixing of an additive (28) in the cement composition (22); - application of the cement paste (22) to the additive (28) having Umhullmasse (20) on the electrical component (12); and - treating the Umhullmasse (20), by treatment of the additive (28) passes from the cement mass (22) to an interface (24) between the Umhullmasse (20) and the electrical component (12), and a function layer (26) at this interface (24) is formed and / or of the Umhullmasse (20) wetted interface (24) increases.
