Abstract (en)
[origin: WO2010000770A1] The invention relates to a vacuum switching tube comprising a first contact piece (7) disposed on a fixed contact bolt (5), a second contact piece (11) disposed on an axial moving contact bolt (9) and a first vapor shield (29) made of an electrically conductive material for protecting the inner surfaces of a housing of the vacuum switching tube from metal vapor depositions. The first vapor shield (29) is held at one of the contact bolts (9) and is electrically insulated against this contact bolt (9).
