<p>The invention relates to a shielding element for the use in medium voltage switchgears with vacuum interrupters with at least two contacts, which are movable along a switching path between closed and open contact position, wherein the shielding element is positioned around the contact position region in the vacuum interrupter, and a method of making the same, according to the preamble of claims 1 and 7. In order to reduce the use of material, and to optimize sametime the energy absorbance behavior of the shielding, the invention is, that at least the inner surface of the shielding is applied with a topographic structure in that way, that the structure is aligned parallel to the switching path of the contacts.</p> |
