Apparatus and method for sealing an electrical connection between an anode structure for cathodic protection against corrosion and a connecting cable with an electrically insulating jacket, an annular body of elastic material, such as rubber for example, which surrounds in a sleeve-like manner the junction between an insulation-stripped end of the connecting cable and a socket on a current feed pin of titanium for the anode structure. By radial compression of a terminal body of plastically deformable material thrust onto the annular body the annular body is pressed at its one end onto the insulating jacket in the end area of the connecting cable and at its other end onto the outer surface of the current connecting pin of the anode structure, in a liquid-tight manner.

Anode structure for cathodic protection against corrosion, and method

An anode arrangement used in electrolytic processes for steel strip galvanizing or chrome-plating has a plate-like anode of titanium with an active surface, which is connected to a generally planar carrier having a steel core and a current supply conductor comprising a sleeve element and a bushing element. The core has a passage extending through it to receive the bushing element, and, for protection against attack by the electrolytic solution, the core is loosely surrounded by an envelope of titanium foil; in the region of the bushing element, the envelope has passages, the edges of which are welded to the bushing element in a gas-tight and fluid-tight manner.
