Abstract: A busbar arrangement for an electrolytic cell utilized for the production of aluminum by electrolysis of molten cryolite salt where the cells are arranged in a side-by-side relationship. In the busbar, the upstream cathode collector and the downstream cathode collector of the upstream cell, the electric connecting arrangements, and the anode risers associated with the downstream cell are combined in the individual busbar modules. In each module, at least one anode riser is situated at the upstream side of the downstream cell and at least one anode riser is situated at the downstream side of the downstream cell. The anode risers at the upstream side are connected to the cathode rods of the upstream and downstream sides of the upstream cell. The anode risers at the downstream side of the downstream cell are connected to the cathode rods and cathode collectors of the downstream side of the upstream cell.

Abstract: A device for compensating a magnetic field in a linearly arranged series of electrolysis cells consists of a combination of main and supplemental electrical compensating conductors. Main inner and outer compensating conductors are spaced from the respective sides of the cells in a series. An inner supplemental compensating conductor is disposed at the bottom of the cells and along the main inner compensating conductor. First and second outer supplemental compensating conductors are disposed at the bottom of the cells. The first supplemental conductor is positioned at the cathode bars at the outer side of the cell. The second outer supplemental conductor is positioned between the first outer supplemental conductor and small axis of the cell.
