Electrical connection device, for connecting between two successive cells of a series of cells for the production of aluminium

The electrical connection device connecting the cells in series comprises: a first conductor (16) connected to the cathode assembly of the cell (N-1) and to the anode frame of the cell (N), having a portion (19) located between said pots (N-1) and (N), and in which portion the current (I) flows towards the alignment axis (X) of the spots; a second conductor (24) connected to the cathode assembly of the cell (N) and to the anode frame of the cell (N+1), having a portion (23) located between the pots (N-1) and (N), and in which portion the current flows away from the axis (X); short-circuiting blocks (20, 21) housed between said portions (19, 23) of said conductors (16, 24); and a third conductor (27) for balancing the current flowing via the blocks.
