Abstract

An electrolytic cell for aluminium production, includes cell walls 17, 18, bus bars 46, 48 external to the cell walls, a carbonaceous cathode block 20 separated from the anodes 12 by the molten electrolyte 14 and metal pad 16, and collector bars 30 connecting the bus bars with the cathode block. The collector bars extend into a slot 24 in the cathode block and are separated at their inner ends by a gap 58. Each collector bar includes a steel 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.
