FIELD: electrolytic production of aluminum, possibly structures of busbars of powerful aluminum cells with fired anodes arranged crosswise in housing.
SUBSTANCE: busbars include cathode rods connected with packs of cathode buses; anode struts connected through cross transmission buses with packs of cathode buses; anode buses provided with jumpers and connected with anodes struts. Busbars include at least five anode struts with next distribution of electric current loads for strut: central and boundary anode struts, 0.8 -1.0 mean electric current load for strut, remaining struts, 1.0 -1.25 mean electric current load for strut determined according to given expression. All cathode rods at each lengthwise side of cell are connected with one cathode pack having at least one cathode bus. Portions of packs of cathode buses, transmission buses and anode struts supplying current load to next cell have differentiated electric resistance providing predetermined electric current load.
EFFECT: lowered circulation speeds of metal and electrolyte, optimal electric current distribution by cathode and anode busbars, reduced electric current losses.
