The invention relates to a method for cooling a superconducting cable (1) using a coolant containing or consisting of liquid nitrogen, wherein at least a part of the coolant is subjected to a subcooling step and thereafter brought into thermal contact with the superconducting cable (1) in a cooling cycle, wherein said subcooling step is at least in part performed using a refrigerant provided in a Brayton process in which at least a part of the refrigerant is cooled and heated in a main heat exchanger (11). According to the present invention, a part of the coolant is withdrawn from the cooling cycle and heated in the same main heat exchanger (11) in which at least a part of the refrigerant is cooled and heated in the Brayton process. A corresponding device and a corresponding system are also part of the present invention.

A road vehicle with an electric drive comprising: at least one pair of drive wheels; a reversible electric machine, which can be connected to the drive wheels; an electronic power converter, which controls the electric machine; an electric energy storage system, which is connected to the electronic power converter; first power wirings comprising at least two first electric wires, which connect the electric machine to the electronic power converter; and second power wirings comprising at least two second electric wires, which connect the electronic power converter to the storage system; and a cooling system, which is thermally coupled to at least one power wiring in order to remove heat from the power wiring.

A flat electrical cable comprises a conductive core having a core sheath and a cooling channel having a cooling channel sheath. The cooling channel and the core extend mutually parallel to one another along a length of the cable and are integrally joined to one another by a web extending along the core and the cooling channel.

A charging cable for an electric car includes an insulating body, a connecting line, and a plug-type connector with contact pins and contact openings. The plug-type connector detachably connects the insulating body to the connecting line via the contact pins and contact openings. Also described is a corresponding charging station.

A charging cable apparatus having a connector, an electrically-conductive cable extending from the connector, the cable configured to be connectable to a charging station for receiving a charging current from the charging station, and having a heat pipe with a phase change section having a wicking structure, the wicking structure having a working fluid therein during operation for receiving heat generated during current flow within the cable. The charging cable apparatus may further have an external condensing surface in fluid communication with the phase change section of the heat pipe for accelerating condensation of evaporated working fluid. The charging cable apparatus may be connected to a charging station for charging an electric battery such as a battery of an electric vehicle.

An electric cable for supplying power to aircrafts, rail vehicles, motor vehicles, ships or other devices is a single or multi-conductor cable and includes one or more current conductors with at least one insulation. A single or multi-layer outer casing is distributed over the periphery and is associated with the outwardly protruding reinforcing elements. The reinforcing elements are in the form of cooling ribs protruding preferably over the entire periphery of the cable and enable the surface of the cable to be increased and as a result, improve heat dissipation. The projecting reinforcing elements considerably reduce the risk of burning when the current conductors heat up and also protect the cable against abrasion. The invention also relates to a plug for the electric cable.
