METHOD FOR PRODUCING CIRCUIT-BREAKER PARTS FOR LOW, MEDIUM AND HIGH VOLTAGE SWITCHING STATIONS AND CORRESPONDING CIRCUIT-BREAKER PART

摘要

The invention relates to a method for producing breaker pole parts or plastic component part units for low-voltage, medium-voltage and high-voltage switchgear assemblies, and to a breaker pole part itself in accordance with the precharacterizing clause of patent claims 1 and 11. In order to obtain simpler manufacture with a greater degree of variance in material properties, the invention proposes that the external insulating sleeve is produced in a plastic injection-molding process by a vacuum interrupter chamber being encapsulated by injection molding.
