The Metso Outotec DoubleContact Busbar System uses equalizer busbars on both the anode and cathode contacts to ensure the current distribution in the cell remains even across all electrodes.
This system provides the current with multiple paths as it goes from the busbar to the electroplating process, allowing operation with higher current densities and current efficiencies. Tests have shown significant results in reduced energy consumption per produced ton of metal, alongside other benefits in tankhouse operations, such as a reduced amount of shorts and less maintenance work required.
