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. A head-end interface of the conductor rod proximate the work machine includes metallic rings spaced apart and extending circumferentially around the head-end interface. Bores pass longitudinally through the head-end interface and into cavities within the conductor rod between the concentric metal tubes. The metallic rings enable the delivery of electrical power radially from the conductor rod for powering the work machine, while the bores enable the delivery of pneumatic power longitudinally into the conductor rod for powering axial movement of the conductor rod.

Abstract: A wire harness unit applied to a power storage device unit and a wire harness includes a routing material and a cooling unit that cools the routing material. The routing material constitutes a charging conduction path that extends between a charging inlet and a power storage device, and transmits electricity. The charging inlet is provided to a vehicle. The power storage device is provided to the vehicle and can store electric power. As a result, the wire harness unit, the power storage device unit, and the wire harness can reduce a cross-sectional area of the routing material to a relatively small area, thereby having an advantageous effect of capable of having proper mountability.

Abstract: An electrical connection component for a machine cable is described. The electrical connection component is suitable for transmission of power with voltage levels greater than or equal to 1 kV and comprises at least one electrical conductor arranged for electrically coupling with a further electrical conductor of another electrical connection component. The electrical connection component comprises a housing having an internal region, and having a machine cable end, a connection end and a plurality of electrically insulating components positioned within the housing, at least one of the electrically insulating components being arranged so as to form-fit with a further one of the electrically insulating components. A portion of the internal region of the housing that is located at the connection end of the housing, and that would not otherwise be filled with the at least one electrical conductor and/or an associated flame path, is filled by the electrically insulating components.
