  • Vaccum Switch Chamber with a Protective Sleeve that is Applied by Heat Shrinking
    Publication number: 20110056916
    Abstract: A resin-encapsulated pole piece is provided and includes a vacuum interrupter chamber having an outer surface. A protective sheath covers the outer surface of the vacuum interrupter chamber. The protective sheath is composed of a heat-shrinkable material. The protective sheath has been pulled over the vacuum interrupter chamber and then heat shrunk so as to be in firm contact with the outer surface of the vacuum interrupter. An outer casing encapsulates the vacuum chamber covered by the protective sheath. The outer casing is composed of a cast epoxy resin and is in contact with the protective sheath.

  • Method for producing a vacuum interrupter
    Patent number: 7832079
    Abstract: The invention relates to a vacuum interrupter chamber and a method for producing the same according to the preambles of patent claims 1 and 3. 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 (1) is provided on the outer surface with a protective sheath (2) 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.
