Good busbar design is of paramount importance for aluminium reduction cell performance. Busbar design has tremendous impact on cell MHD-stability, without which it is difficult to achieve high current efficiency and low energy consumption since instabilities enhance the rate of back reaction and make pot control more difficult. Many aspects of busbar design and MHD-stability are still grey areas in which cell designers do not have full confidence because MHD criteria are still rather qualitative. EGA has developed cell design capabilities, including busbar design. During the last six years, EGA has developed about ten busbar designs for new and retrofit potlines. In some cases, the constraints led to sub-optimal busbar design for cell stability in practice. This experience enhanced our understanding of the busbar design, MHD modelling and measurements, which we share in this paper and discuss criteria for busbar temperature, current density and vertical magnetic field bias.
