摘要： 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.

摘要： A copper-aluminum composite electric energy transmission system and a processing method therefor are disclosed. The system includes a copper terminal (1) and an aluminum cable (6). The aluminum cable (6) includes an aluminum conductor (2) and an insulation layer (3) cladding a periphery of the aluminum conductor (2). The system further includes an electric energy transmission aluminum piece (4), in which a section of the aluminum conductor (2) with the insulation layer (3) stripped from the aluminum cable is pressed to form a connecting piece. The electric energy transmission aluminum piece (4) and a front end of the aluminum conductor (2) form a molten layer (5). An end of the copper terminal (1) for being welded to the electric energy transmission aluminum piece (4) is provided with a welding platform (11). The molten layer (5) dads the welding platform (11) to form a transition layer (12) with metal atoms penetrating into or combined with each other. By reducing an internal stress between copper and aluminum, the mechanical property of a copper-aluminum welding joint is improved. Copper-aluminum compounds in the transition layer (12) are reduced, and the electrical property of the copper-aluminum welding joint is improved. Meanwhile, a path of the transition layer (12) to resist an erosion from an external environment is extended, thereby solving the metal corrosion problem of the copper-aluminum welding joint, and prolonging the service life.

摘要： Proposed is a novel embedded structure for suppressing a disturbance in the cross sectional shape and a non-uniform deformation of a metal member arising in a precursor when producing an MgB2 multi-core wire material by a surface reduction process. This superconductive multi-core wire material precursor is characterized by having: soft Cu and Fe pure metals disposed in the center; mixed powder elements, each comprising as a sheath material a metal such as Fe or Nb having a barrier effect preventing a reaction between Mg and Cu, the mixed powder elements being disposed in a form that surrounds the periphery of the soft metal serving as the central material; and disposed around these, an outer shell layer produced from a harder metal than the central material and the sheath material.

摘要： A cable assembly includes a plug receiver, a conductor interface, a metal shell encasing the conductor interface and a portion of a cable of the cable assembly, a metal foil that wraps conformably around an exterior of the metal shell, wherein the metal foil covers substantially all of the exterior of the metal shell and extends beyond the metal shell onto a cable shielding layer. The cable assembly further includes a solder layer disposed about the metal foil, wherein the solder layer bonds and electrically couples the first foil portion to itself, the second foil portion to cable shielding at the location on the plurality of conductors that is proximate to the conductor interface, and the third foil portion to the plug receiver. The cable assembly further includes an electrically insulating layer that encases the metal shell, the metal foil, and the solder layer.

摘要： Electrochromic devices and methods may employ the addition of a defect-mitigating insulating layer which prevents electronically conducting layers and/or electrochromically active layers from contacting layers of the opposite polarity and creating a short circuit in regions where defects form. In some embodiments, an encapsulating layer is provided to encapsulate particles and prevent them from ejecting from the device stack and risking a short circuit when subsequent layers are deposited. The insulating layer may have an electronic resistivity of between about 1 and 108 Ohm-cm. In some embodiments, the insulating layer contains one or more of the following metal oxides: aluminum oxide, zinc oxide, tin oxide, silicon aluminum oxide, cerium oxide, tungsten oxide, nickel tungsten oxide, and oxidized indium tin oxide. Carbides, nitrides, oxynitrides, and oxycarbides may also be used.

摘要： A flexible flat cable manufacturing system comprises a tape conveying device conveying an adhesive tape along a first direction, and a wire conveying device conveying a row of wires along a second direction perpendicular to the first direction and parallel to a width direction of the conveyed adhesive tape. A wire pressing device presses and pastes the part of the row of wires facing the adhesive tape onto the adhesive tape. A wire cutting device cuts the row of wires to obtain a row of wire segments pasted on the adhesive tape and separated from the row of wires and produces a flexible flat cable including the adhesive tape and the wire segments pasted on the adhesive tape.
