Abstract: An electric high-voltage insulator made from plastic comprises at least one glass fiber rod (1), at least one shield covering (2) made from silicone rubber which surrounds the glass fiber rod (1) and has concentric bulges (3) arranged along the longitudinal axis and bent in the shape of sheds in such a way that they form a convex top side and a concave or flat underside, as well as metal fittings (5) on both insulator ends. In this case, the bulges bent in the shape of sheds have at least one groove (4) on the underside preferably with a minimum depth of 1 mm.

Abstract: A process for producing an electric heating element is disclosed whereby metallic heating conductors are embedded between ceramic insulating layers, and, as power supply leads and power outlet leads, contact recesses in the ceramic insulating layers are filled with an electrically conductive composition. The heating conductors, the power supply leads and the power outlet leads are applied to the ceramic layers in the green state as metallizing paste containing from 60 to 95% by weight of metal particles and from 5 to 40% by weight of inorganic powder, based on the total solids content of the paste. The ceramic layers with the applied metallizing pastes are then stacked on top of one another and then sintered.
