A method for production of a pole part of a medium-voltage switching device, and a pole part are provided. To obviate costly pressure reinforcements at least on the switching contact side of the vacuum interrupt chamber in the area of the mold core, while also achieving an optimum injection-molded result, a compensation ring is positioned, before the encapsulation process, as a separate injection-molded seal on or close to the external circumferential line of a vacuum interrupt chamber cover, between the lower cover of the vacuum interrupt chamber and the mold core. The positioned compensation ring is also encapsulated so as to remain in the encapsulation, and the mold core is then removed.

The disclosure relates to a method for producing circuit-breaker parts and plastic components for low, medium and high-voltage switching stations and to a corresponding circuit-breaker part. To obtain a simpler method of production with a higher variance of material characteristics, the outer insulation sleeve is produced in a plastic injection molding method, in which a vacuum interrupter chamber is sheathed in plastic.

The invention relates to a vacuum interrupter chamber and a method for producing the same according to the preambles of patent claimsand. In order here to improve a vacuum interrupter chamber of this type and a method for producing the same and the subsequent casting to the extent that the advantages described above are utilized but the disadvantages described are avoided, it is proposed according to the invention that, in preparation for later casting, the vacuum interrupter chamber () is provided on the outer surface with a protective sheath () consisting of an elastic or elastomeric or plastomeric material, which is applied to the surface of the vacuum interrupter chamber without further expanding mechanical aids by heat shrinkage alone.

A power switching device for use in a power distribution network has a conductive element that is shaped in a non-cylindrical form. The non-cylindrical shape of the conductive element allows the non-conductive material such as epoxy that is used to form the body of the device to securely fasten the conductive element in place to thereby keep the conductive element from rotating when excessive rotational force is applied to the conductor. The conductive element can be shaped with a protrusion or in a C-shape. The protrusion and C-shape help prevent rotation of the conductive element when a threaded bolt is applied to secure a power cable to one end of the conductive element.
