Abstract
The invention relates to a bellows in a vacuum capacitor, whose bellows structure (1) comprises a carrier material (2) and at least one electrically conductive layer (5, 6), whereby the latter has a uniform thickness over the entire bellows structure. The deviations of the layer thickness from the mean are less than ±50% and preferably less than ±10%. This results in an increased life span with mechanical loading. In order to increase the heat emission through radiation, the bellows structure (1) has an additional dark layer (7). The used method provides for the application of the electrically conductive layers prior to the shaping process, which results in homogeneous layer thicknesses.
