FIELD: electrolytic processes and equipment. SUBSTANCE: invention relates to structure of current-supply rod of electrolyzer with self- burning anode. Cylindrical part of steel rod of cylindrical-conical steel-aluminium current-supply rod connector contains outside aluminium cylinder being in tight contact with rod surface. Diameter of cylindrical part of steel rod may be decreased by thickness of aluminium cylinder, ratio of inner to outer diameters of this cylinder being at least 0.6:1. Cylinder may be made with variable thickness of wall decreasing in current direction and may consist of two parts. In this case, a part of cylinder or whole cylinder may be constructed as a whole with aluminium current-supply bar, and "aluminium cylinder-steel rod connector" contact may be made on diffusion level, for example, be welding or explosion technique. EFFECT: improved structure. 6 cl, 2 dwg, 2 tbl
