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.

Disclosed is an opto-electric cable including one or more electrical conductors. Each conductor includes an electrically conductive core and an electrically insulating layer surrounding it. The cable also includes an optical unit embedded within one of the electrically conductive cores. The optical unit includes at least two optical fibers and a single buffer jointly surrounding all the optical fibers. Each optical fiber includes a core, a cladding and a coating. Since all the optical fibers of the optical unit are jointly surrounded—and protected—by a single buffer, an optical unit with a reduced size is obtained. This allows reducing the cross section of the electrical conductor in which the optical unit is arranged. In particular, electrical conductors with cross section lower than 10 mm.sup.2 are obtained.

An arrangement for welded conductors for power transmission cables is provided, with conductors welded by a high conductive welding material. A method is also provided for production of welded conductors and power transmission cables including the welded conductors.

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.

The present invention relates to an electromagnetic shielding device comprising (40) at least one hollow protective textile sleeve (50) having a main rest diameter D1 and an interior volume configured to receive one or several elongated element(s) (20, 21), at least one hollow connecting textile sleeve (60) having a rest diameter D2, D2 greater than D1.

At least one of the plurality of internal cables includes at least one electric wire having a conductor, a first sheath covering a periphery of the at least one electric wire, a shield covering a periphery of the first sheath, and a second sheath covering a periphery of the shield.

A power cable assembly and a power distribution system incorporate an integrated cooling system. The power cable assembly comprises a power cable core comprising an electrical conductor an electrical conductor extending longitudinally, a plurality of longitudinally extending cooling pipes, and a thermal interface material (TIM) surrounding the cooling pipes and electrical conductor. The TIM is configured to thermally couple an external surface of the thermally conductive wall of each cooling pipe with an external surface of the insulating material of the electrical conductor such that the heat generated at the electrical conductor is transferred, via the external surface of the cooling pipes over a heat transfer region, to the coolant medium circulating in the interior channel.

A high voltage power cable assembly for a power distribution system of a vehicle incorporating an integrated cooling system is presented. The power cable assembly comprises first and second electrical conductors spaced apart from one another and extending longitudinally. The power cable assembly further comprises a longitudinally extending cooling tube arranged between the first and second electrical conductors such that opposing portions of an external surface of the cooling tube are provided in direct contact with corresponding portions of the insulating material of the electrical conductors over a heat exchange region so as to transfer heat from the electrically conductive core of the electrical conductors to a coolant medium circulating in an internal channel of the cooling tube.

A flat flexible cable (FFC) assembly, which includes a multi-FFC cable having a plurality of FFC films arranged in a layered form and an insulation tube for surrounding the plurality of FFC films, and a pair of high current terminals mounted to respective ends of the multi-FFC cable.

High-voltage power line cables for electric power transmission and, in particular, cable conductors for overhead electric power transmission and methods of making such conductors are disclosed. Methods for revamping in-stock and deployed cable conductors for overhead electric power transmission also are disclosed. Each cable conductor has an outermost surface defined by strands that are wrapped around a core of the cable conductor. Indentations are formed in the surfaces of the strands preferably such that an arrangement of dimples extending circumferentially around a longitudinal axis of the cable conductor repeats along a longitudinal direction of the cable conductor. The surface indentations preferably define a dimpled surface of the cable conductor.
