Abstract: Disclosed is a system of current-supply buses for aluminum-producing electrolyzers arranged transversely in a row and spaced from each other. The system comprises cathode stacks, anode risers installed in the spaces provided between the electrolyzers, and anode buses for supplying current from the anode risers to electrolyzer anode systems shaped as parallelograms. At least two of the anode risers of each electrolyzer are arranged past the planes passing through the end edges or borders of the anode systems. The proportion of the anode risers so arranged is determined such as to ensure the symmetric distribution of the magnetic field intensity components.

Abstract: A dual current supply system for aluminum-producing electrolyzers longitudinally arranged in a series-connected row comprises at least four anode risers in each space between next-adjacent electrolyzers. The system includes anode systems and anode buses electrically connected to the anode risers for supplying current from the anode risers to the anode systems. Two of the anode risers of one of a pair of next-adjacent electrolyzers are coaxially positioned in the space between the next-adjacent electrolyzers and two of the anode risers of the other of the pair of next-adjacent electrolyzers are positioned in the space between the next-adjacent electrolyzers in coplanar relation with the anode risers of the one of the next-adjacent electrolyzers. The arrangement of the anode risers enables a more uniform distribution of the magnetic field and permits the total length of the electrolyzer body and current supply buses to be reduced.

Abstract: A system of busbars for aluminium-producing electrolyzers located at the ends of groups of series-connected electrolyzers arranged lengthwise in at least two parallel rows, incorporates stacks of cathode buses located to the left and to the right of a longitudinal axis of each row of electrolyzers in the direction of the current flow through the electrolyzers. The system incorporates a busbar jumper connecting the busbars of the first electrolyzer located at the end of one of the two rows of electrolyzers wih the busbars of the second electrolyzer located at the end of the other of the two rows of electrolyzers.
