Introducing a Bypass-Backup Connection System for Current-Mode Copper Electrowinning Intercell Bars

The proposed system is suitable for current-mode segmented intercell bars. Previous developments show that these bars provide protection against short circuits but are sensitive to open circuits and dirt contacts. This new system adds segmented sidebars to interconnect in groups the otherwise electrically insulated cathode and anode hanger ends. The combination of a segmented main bar with these sidebars offers protection against short circuits, open circuits, and impaired contacts.
