Summary: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, according to claim 1. In order to enhance the energy absorbance behavior of the at least the shielding, at least the inner surface of the shielding is applied with a topographic structure which is a rough at least partly disordered surface structure.
