Bundled cables and methods for preparing bundled cable are disclosed herein. In the method, a plurality of subunits is wound about a central member. The subunits include a subunit jacket made of a first thermoplastic composition and has a first outer surface, and the central member includes a central member jacket made of a second thermoplastic composition and has a second outer surface. A metal element is provided at an interface of the second outer surface and the first outer surface of the subunits. The metal element is heated such that at least one of the first thermoplastic composition or the second thermoplastic composition forms bonds with the other of the first thermoplastic composition or the second thermoplastic composition.

A power cable includes an electric conductor; an electrical insulation layer surrounding the electrical conductor; a cooling system including a cooling duct substantially parallel to the electrical conductor along a power cable longitudinal axis and configured to flow a cooling fluid; a carbon allotrope layer in direct contact with the electrical conductor, where the carbon allotrope layer is provided between the electric conductor and the cooling duct; and a cable jacket enclosing the electric conductor, the electrical insulation layer, and the cooling system.

A cable is provided having at least one electrically insulating layer obtained from a polymer composition with at least one polypropylene-based thermoplastic polymer material and at least one inorganic filler selected from aluminium oxide, a hydrated aluminium oxide, magnesium oxide, zinc oxide, and a mixture thereof; and a method for making the cable.

A cooled system includes an enclosure having an outer surface and an inner surface comprising a cooled enclosed area, multiple cable brackets thermally coupled to the outer surface of the enclosure, each cable bracket including a first surface conforming to the outer surface of the enclosure and an opening therethrough sized to hold a cable and conduct heat from the cable to the outer surface of the enclosure.

A cable system is provided which is configured with both electric wires and a fluid conduit running through the axial passage of a surrounding flexible sheath of the cable. The system allows for communication of electricity over the wires for electrical circuits and concurrent communication of a fire ignition suppressant fluid or gas through the fluid conduit, to all points in an electric circuit using the cable. One or both of a dye or scent can be included in the ignition suppressant fluid.

A liquid cooled charging cable system may be provided. The liquid cooled charging cable system may comprise a source, a load, a liquid cooled charging cable, and a cooling device. The liquid cooled charging cable may connect the source to the load, and may supply electric energy from the source to the load. The liquid cooled charging cable may comprise a supply conductor and a return conductor. The cooling device may pump a coolant around the supply conductor and the return conductor where the supply conductor and the return conductor may be immersed in the coolant.

Fluidic channels and pumps for active cooling of cables are described. One cable assembly includes a conductor having a length between a first end of the cable and a second end of the cable and a fluidic channel structure that at least partially surrounds the conductor along the length of the conductor. A first pump connector is coupled to a first end of the fluidic channel structure and a second pump connector is coupled to a second end of the fluidic channel structure. Motion of liquid metal, when pumped through the fluidic channel structure, distributes heat away from the conductor.

The invention is directed to a cable assembly (10, 10a-b), comprising a cable (10, 10a-b) with a cable hose (11, 11a-b) and at least one conductor (12, 12a-f) arranged therein. The cable hose (11, 11a-b) is spaced a distance apart from the conductor (12) forming a first interstitial space (15, a-b) between the at least conductor (12) and the cable hose (11, 11a-b). At least one tube (20, 20a-b) for conveying of a cooling fluid (21), and a connector (30) comprising at least one contact member (31) interconnected to the at least one conductor (12) and a chamber (32). Said chamber (32) comprises a first port (33) which is interconnected to the first interstitial space between the at least one conductor (12, 12a-f) and the cable hose (11, 11a-b) and a second port (34a, 34a-b) which is interconnected to the at least one tube (20, 20a-b).

A power cable system including a power cable, and an evaporator pipe assembly extending along the power cable, wherein the evaporator pipe assembly having an inner liquid pipe including a pressurised liquid refrigerant, and an outer gas pipe arranged outside of and coaxially with the inner liquid pipe, wherein the inner liquid pipe is provided with a plurality of openings distributed along its length, and wherein the openings provide fluid communication between the inner liquid pipe and the outer gas pipe, allowing part of the pressurised liquid refrigerant to escape from the inner liquid pipe to the outer gas pipe and evaporate in the outer gas pipe, thereby cooling the power cable.
