Abstract
This aluminum smelter comprises a line of electrolytic cells arranged transversely to the line, one of the cells comprising anode assemblies and electrical conductors mounted and connecting the anode assemblies. Rising and connecting conductors extend upwardly along two opposite longitudinal edges of the cell. In addition, the aluminum smelter comprises a first electrical compensating circuit extending under the cell and which can be traversed by a first compensating current in the opposite direction to that of the electrolysis current, a second electrical compensating circuit extending on one side of the line that can be traversed by a second compensating current in the same direction as the electrolysis current.
