Abstract

A work machine, such as a hauler at a mining site, includes a conductor rod housing concentric metal tubes for receiving electrical power from a contactor sliding on a power rail. Electrical connectivity between conductors within the conductor rod, between the concentric metal tubes, are provided using a conductive liquid. Corrosion barriers are used to protect the concentric metal tubes from corrosion resulting from contact with the conductive liquid. The corrosion barriers are electroplated and include nickel phosphide and/or cobalt phosphide to maintain the electrical connectivity between the conductors, while protecting the conductors from corrosion.
