A current connection apparatus for a pressure tank is provided. The current connection apparatus includes a tank flange mounted on a tank and an opening that leads into the tank. Electrical connection cables are installed in this opening for connecting with an external electrical apparatus. An electrical lead having one or more conductors, which are electrically insulated relative to a metal flange, and a protective casing. The electrical lead is disposed between the tank flange and the protective casing and is tightly fastened to the tank flange. A plug body, which has plug elements corresponding to conductors of electrical lead, is inserted into the tank opening in the tank flange. The protective casing also has a plug body inserted therein, where the plug body has plug elements.
