Abstract: The subject of the invention is a cover (2) with an electrical lead through connector (1) for connecting MV or HV conductor (7) with a load (4) placed in a tank containing a dielectric liquid or dielectric gas. An electrical lead through connector (1) comprises a plug-in bushing member (5) made of insulating material, where a series filtering choke (6) is embedded. The filtering choke (6) has a first terminal (6a) which is electrically connected with an external HV or MV line (7) and has a second terminal (6b) which is connected to a load (4) placed inside the tank (3). The lead through connector (1) is further provided with an additional bushing member (9) which is mechanically connected with the plug-in bushing member (5) through a common insulating base (8). The additional bushing member (9) is equipped with a conductor (10) located inside the bushing member (9), where the conductor (10) is directly connected with the second terminal (6b) of the filtering choke (6) and with an external protective component (11) against electrical surges.
