The invention relates to a busbar arrangement for heavy-duty aluminum electrolyzers when said electrolyzers have a longitudinal position. The busbar arrangement comprises anode busbars, risers and cathode rods, which are divided into groups, each of which is connected to separate cathode busbars, wherein the cathode busbars for the groups of rods closest to the input end of the preceding electrolyzer are connected to the risers positioned at the input end of the following electrolyzer, and the remaining groups of cathode rods are connected to the risers at the output end of the following electrolyzer. The cathode busbars for the groups of rods closest to the input end of the preceding electrolyzer are positioned beneath the base of the preceding electrolyzer, and the cathode busbars of the remaining groups of rods are positioned beneath the base of the preceding and the following electrolyzers or of the preceeding and following electrolyzers and along the cathode sheath on the front face side of the following electrolyzer. The risers at the input end of the following electrolyzer are mounted with an offset towards the center of the electrolyzer relative to the risers at the output end of the following electrolyzer. A high degree of compensation of electromagnetic forces in the melt is achieved by virtue of optimization of the configuration of the magnetic field in the electrolyzer bath and a reduction in the vertical magnetic field.
