  • Such busbars typically comprise collecting busbars in combination with associated cathode flexible electrical conductors which are arranged along upstream and downstream longitudinal sides of the cell.
  • Anode risers situated at the upstream side of the cell are provided for transmitting similar electrical currents there-through.
  • the anode busbars of the downstream cell are connected to a neighboring upstream cell by risers.
  • the outer risers are connected to the outer cathode collectors of the upstream side of the upstream cell by flexible electrical conductors positioned along the transverse sides of the cell.
  • the outer risers are also connected to collecting cathode busbars or cathode collectors of the downstream side of the upstream cell.
  • the intermediate risers are connected to the intermediate cathode collectors or collecting busbars of the upstream side of the cell by the flexible cathode conductors positioned symmetrically under the cathode blocks situated in the close vicinity to the end sides of the cell.
  • the intermediate risers are also connected with cathode collectors or collecting cathode busbars of the downstream side of the upstream cell.
  • the busbar situated under the bottom of the cell and disposed in the vicinity of the neighboring row of the cells carries 15% of the current at the upstream side of the cell. On the other hand the other busbar carries 10% of the current at the upstream side.
  • An intermediate busbar is also situated under the bottom of the cell and extends in to the midpoint between the longitudinal axis of the row of the cells and the cell end on the side opposite to the neighboring row of cells. This busbar carries 5% of the current at the upstream side.
  • the busbar arrangement discussed hereinabove is described in French Patent No. 2,552,782.
  • busbars and risers are subject to various restrictions.
  • One such restriction is that the busbars and risers should be arranged so as to minimize the general magnetic field induced in the cell.
  • the vertical component of such magnetic field should be minimized.
  • the vertical component of the induced magnetic field interacts with the horizontal component of the electric currents in the molten metal pad giving rise to horizontal forces which can affect different regions of the metal pad in different ways. These forces may result in undesirable metal motion, humping of the metal surface, and wave formation.
  • the busbars extending from the cathode collector bars of the upstream cell to the anode busbars of the neighboring downstream cell are much longer than the portions of the busbars of the collector bars at the downstream side.
  • the sectional area of the busbars from collector bars at the upstream side is limited by the density of current they carry.
  • the ratio of such sectional area to the density of the current passing therethrough should not exceed 0.75 A/mm 2 .
