Embodiments of a liquid-cooled charging cable are described. The charging cable includes one or more electrically conductive cables having a first end and a second end. Each cable has a set of one or more cooling tubes. Each cooling tube includes an inlet and an outlet, both at the first end of the cable, a forward part in thermal contact with the cable, the forward part beginning at the inlet and extending from the first end to the second end, and a reverse part in thermal contact with the cable, the reverse part extending from the second end to the first end and ending at the outlet. The forward and reverse parts together form a continuous fluid path between the inlet and the outlet, so that a working fluid can flow through each cooling tube from the inlet through the forward part and the reverse part to the outlet.

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 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.

The invention relates to an electrical power supply cable (10) for a photovoltaic installation, comprising an electrical conductor (12) having at least two electrical conductor portions (20, 22) and a fuse (24) arranged between said at least two electrical conductor portions, said at least one fuse electrically linking said at least two electrical conductor portions, the cable (10) further comprising a protection element (30, 40, 50, 60) overmolded around said fuse and forming an electrical insulation layer, said protection element comprising at least one overthickness at at least one end portion (34, 36) of the protection element (30).

A polymer composition comprising (i) at least 70 wt% of low-density polyethylene (LDPE) homopolymer or copolymer having a density of 905 to 935 kg/m.sup.3 (ISO 1183-2) and an MFR.sub.2 of 0.1 to 10 g/10 min (ISO1133 at 190° C., 2.16 kg); (ii) 0.5 to 20 wt % of a high density polyethylene (HDPE) having a density of 940 kg/m.sup.3 or more and an MFR.sub.2 of 0.1 to 50 g/10 min; and (iii) 0.05 to 10 wt% of an aliphatic, preferably alkyl, functional inorganic nanoparticle filler.

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.

A power cable having a central ground conductor. Phase interweave power conductors are positioned about the central ground conductor. Individual phase interweave power conductors have the same diameter. The individual phase interweave power conductors have a cross sectional area which is optimized. Each of the individual phase interweave power conductors is configured to support 100% cross sectional usage to maximize power carrying capability. The power cable reduces the skin effect of the power cable and the proximity effect of the power cable.

Electrode foil (6) comprising a) an electrode layer (60) comprising—a sensing electrode portion (100), operable as an electrode of a sensing capacitor for sensing a voltage of an inner conductor (20) of a medium or high voltage power cable (10),—a first auxiliary electrode portion (200), electrically isolated from the sensing electrode portion. The electrode foil further comprises b) a non-conductive carrier film (71) carrying both the sensing electrode portion and the first auxiliary electrode portion, and c) an adhering surface portion (90) for attaching the electrode foil to an exposed insulation layer (30) of the power cable.

An electric vehicle supply equipment (EVSE) having ability to charge electric vehicle from indoor located 208-240V outlets. The EVSE comprises a flattened armored cable to securely transmit electrical power to outdoor location from indoor located electrical source. In the preferred embodiment, the flattened armored section acts as EVSE anchoring system which providing ease of installation when temporary electric vehicle recharging is required. The EVSE has ability to disconnect electrical power passing through the flat armored cable in case of non proper conditions or if any electrical hazard occurs. A further embodiment comprises a flexible version of flat cable. To enhance its electrical safety, flat wire conductor comprising damage sensor is used to improve the electrical safety. The EVSE may validate flat wire physical integrity before applying electrical power to the flattened flexible cable.

An electrical cable is provided with a rounded insulated electrical conductor that transitions to a flattened section to fit into areas where the rounded portion does not fit. A round electrical conductor transitions to a flattened section for electrical conduction routing via the undercarriage of a vehicle, for routing under the carpeting of the passenger compartment, or other confined spaces. The electrical cable may illustratively be used in an electric car application where distribution of electrical current from the battery compartment to the motor requires additional wiring in the vehicle not found in combustion based engines. The reduced vertical profile of the flattened section provides for additional clearance between the vehicle undercarriage and the road, or between the undercarriage frame and the interior passenger compartment carpet.
