Abstract
The invention relates to a device for reducing magnetic disturbances in a series of very high intensity electrolysis cells. The device is characterized by the supply of an anode bus bar both through its two ends and through at least one central riser supplied from upstream cathode outputs and by a branch on the downstream cathode output rods of the preceding cell. Application is to the production of aluminum by electrolysis of alumina in molten cryolite.
