Abstract

An insulating component for use in high-voltage switching equipment, especially gas-insulated switching gear. A nozzle made of an insulating material is used in a power switch. Portions of the surface of the nozzle subject to high dielectric stresses in use are provided with increased surface roughness in the form of grooves. These grooves may be cut by a lathe.
