Abstract

An electrolytic cell (4) for aluminum production, including a cell wall (7, 18), a bus bar (46, 48), a carbonaceous cathode block (10), and a collector bar (30) connecting the bus bar with the cathode block. The collector bar comprises a ferrous metal body including a solid spacer (32) and a sheath (33) defining a cavity (34) containing a copper insert (40). The spacer has an external end portion (35) connected with the bus bar and an internal end portion (36) that is preferably spaced inwardly of the cell wall. The spacer separates the copper insert from the bus bar, thereby reducing heat loss from the cell.
