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 are provided using a conductive liquid. Corrosion barriers are used to protect the conductors while maintaining the electrical connectivity between the conductors.
