Casting part for producing e.g. component, in central and high voltage engineering, has circular front edge whose outside limitation surface is turned towards rotating undercut, where front edge is towered at top axially from rotating edge

摘要

The casting part (20) has an insulating material (30) i.e. duromer, comprising a rotationally symmetric bush-shaped base part with a radially expanding end section. A rotating edge of the end section is radially rounded off. The rotating edge is curved in a direction of an axis of the casting part, and comprises a rotating undercut opening radially outward to the base part. A circular front edge lies radially in a rounded-off manner. An outside limitation surface of the circular front edge is turned towards the rotating undercut. The front edge is towered at top axially from the rotating edge.
