ABSTRACT:
A current-feeding cathode-mounting device comprises a metal-sheathed carrying rail of copper and a permanent cathode plate consisting of the same material as the sheath and joined by welding at least along part of a longitudinal edge and wherein at least an end portion of the rail is unsheathed at least along part of its extent. In order to increase the creep strength and durability and to ensure a low-resistance contact, the carrying rail consists of a hollow copper section, the sheath consists of special steel, the sheath is joined to the carrying rail by a diffusion-preventing non-porous weld, and the permanent cathode of special steel is joined to the sheath by an interrupted seal weld. The carrying rail consists suitably of a copper tube. In accordance with a further feature the copper tube provided with a special steel sheath has been deformed to constitute a composite having an elliptical or oval cross-section or a cross-section having two parallel sides, and the major axis of said cross-section lies in the plane of the cathode plate.
