The invention relates to a crosswise arrangement of electrolysis pots for the production of aluminum py igneous electrolysis according to the Hall-Heroult process, including at least one first line of electrolysis pots forming a first electrical circuit and at least one second electrical circuit located at a determined average distance from the first line, characterized in that at least one conductor called an "axial" conductor passes under each upstream pot in the central zone, in that at least one conductor called a "lateral" conductor passes under each upstream pot in the inner lateral zone, in that at least one "bypass" ..- conductor bypasses each upstream pot, in that the or each lateral conductor is connected to a first set of the said cathodic ends located on the upstream side in order to transmit a first part II of the current Im, between 10 and 20% of the said current Im, to the said risers, and in that the or each axial conductor is connected to a second set of the said cathodic ends located on the upstream side in order to transmit a second part I2 of the said current Im, between 10 and 20% of the said current Im, to the said risers, in that the or each bypass conductor is connected to a third set of the said cathodic ends located on the upstream side in order to trahsmit a third part I3 of the current Im corresponding to the rest of the lurrent Im, in that the said risers are connected to the cathodic ends located on the downstream side of the corresponding upstream pot, to the conductors passing.
