A power cable or a hybrid power-data cable includes power conductors and a plurality of continuity wires positioned radially outside of the power conductors. The continuity wires are positioned relative to the power conductors such that a cut in the cable will sever one of the plurality of continuity wires before a cut into the power conductors can occur.

A thermal management system for a power and fiber splice enclosure that includes a housing including electrical components is provided. The thermal management system includes a solar shield disposed external to the housing and covering at least a major portion of the housing. The thermal management system includes a vent disposed in the housing for venting hot air from the enclosure.

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.

Flexible cables may include multiple power, ground, and signal traces, and include EM interference suppression devices within the cable itself. Signal traces may be shielded by ground traces.

In one embodiment the disclosure provides a portable and mountable apparatus and method capable of powering and deploying an illuminable tether to an unmanned robotic device (flying drone, ROV, terrestrial robot, to be referred to as a “URD”) that not only can provide power and command control to the robotic device, but also receive telemetry back from said robotic device's sensor(s) and data gathering instrumentation transferable to an operator's interface.

A power cable assembly includes a power cable core. The power cable core has a longitudinally extending cooling tube comprising a thermally conductive wall defining an interior channel for circulating, between a coolant inlet and a coolant outlet of the cooling tube, a coolant medium; a longitudinally extending electrical conductor configured to be coupled via first and second connectors to respective electrical connections of a power distribution system; and a first insulating layer surrounding the power cable core. The electrical conductor is arranged to surround the cooling tube at least partially such that at least a portion of an external surface of the thermally conductive wall is provided in direct contact with a corresponding portion of the electrical conductor over a heat exchange region so as to transfer heat from the electrical conductor to the coolant medium circulating in the interior channel of the cooling tube.

An active cable avoiding influence of RX power consumption, comprising: the host connection end, the device connection end and the data wire and the auxiliary wire located between them. The auxiliary wire consists of the main power wire and the auxiliary power wire, wherein, the main power wire is used for current transmission between the VBUS of the host and the device; the auxiliary wire, one end of it is located at the host connection end and connected with the main power wire, and another end at the device connection end and is used for supply power to the active component at the device connection end. The present invention disconnects an active module of the device connection end from the VBUS , thereby solving excessive IR-drop of VBUS; the present invention also arranges the power module between the active component and the auxiliary wire.
