Bendability of an insulated wire having a separator layer interposed between a conductor and an insulating layer is improved. The insulated wire has a conductor; a separator layer formed of separator tapes wound on the conductor; and an insulating layer arranged on a periphery of the separator layer. The separator tape is spirally wound so that width-directional parts of the separator tapes are overlapped with one another, and a plurality of overlapped portions at which the width-directional parts of the separator tapes are overlapped with one another to be three- or more-layered exist in a longitudinal direction of the conductor.

A rectangular cross-section multi-core insulated wire includes an assembly of wires in which insulating layers are formed on peripheries of conductors, and the assembly of the wires is a composite twisted structure, and includes first twisted wires formed by twisting the wires, second twisted wires formed by twisting the first twisted wires, and third twisted wires formed by twisting the second twisted wires. An insulating fiber thread is wound around a periphery, a cross-section is formed in a rectangular shape, and a winding direction of the fiber thread is a direction opposite to a twisting direction of outermost twisted wires in the assembly of the wires.

By using an electrically conductive PTFE fabric, high-voltage insulation systems are simplified and can be made thinner, also improving the thermal conductivity. The insulation material is in two layers, each with a hydrophobic and a hydrophobic region, and the hydrophobic regions of the layers are opposed.

A fluoropolymer composite film wire or cable wrap comprises an outer layer of expanded polytetrafluoroethylene (ePTFE) and an inner layer of melt processable fluoropolymer film. The inner and outer layers are laminated with each other in tape form, such as by the application of heat and/or pressure thereto. The fluoropolymer composite tape is wrapped about one or more wires or cables, and is heated or sintered after wrapping to bond the tape to the wire or cable, and bond the tape to itself at the seams.

Superelastic conductive fibers, and more particularly, sheath-core fibers for superelastic electronics, sensors, and muscles, and a process for fabricating of highly stretchable sheath-core conducting fibers by wrapping fiber-direction-oriented conductive nanofiber sheets on stretched rubber fiber cores.

A coaxial cable includes a coaxial wire in which an inner insulator, an outer conductor and a sheath are sequentially and coaxially provided around a center conductor, and a substrate having a surface on which a first contact pad and a second contact pad are arranged. The sheath is removed at one end portion of the coaxial wire by a predetermined length, so that the inner insulator and the outer conductor are exposed, and a tip end of the inner insulator is removed by a predetermined length, so that the center conductor is exposed. The exposed portion of the center conductor is soldered to the first contact pad with the exposed portion of the inner insulator being bent relative to the sheath, and the exposed portion of the outer conductor is soldered to the second contact pad with being bent in a direction different from the bending direction of the inner insulator. A part of the coaxial wire covered by the sheath is standing at an angle of 30 or greater relative to the surface of the substrate.

A sheathing for an elongated product, including an electrical cable set, having a foldable, wrappable, arching or bendable carrier having a middle region provided for lying against the elongated product and is delimited on both sides by an edge region. In order to ensure an attachment, which can be carried out with reduced effort during the mounting of the sheathed product, at least one hole is located in each edge region, wherein a hole in the one edge region is associated with a hole in the other edge region, such that the holes coincide by a folding of the carrier along or parallel to a main axis (X-X) that extends through the middle region of the carrier, or by an arching or bending of the carrier about an axis (Y-Y) parallel to the main axis (X-X).

A parallel pair cable includes a pair of insulated electric wires aligned in parallel, a shield tape longitudinally wrapped around the pair of insulated electric wires, a drain wire disposed inside the shield tape, and an insulating tape wrapped on an outer side of the shield tape. The shield tape has a metal layer provided on an inner surface thereof. The drain wire is provided to electrically contact the metal layer. A surface of the metal layer is provided with an adhesion surface having an adhesive applied thereto. The adhesion surface and the pair of insulated electric wires are adhered to each other. An area of the adhesion surface is 30% to 70% of a surface area of the metal layer.

An electric cable includes at least one electric wire, and a plurality of string-shaped bodies each extending in a longitudinal direction of the electric cable and twisting with one another around the at least one electric wire being a core. The plurality of string-shaped bodies has connection parts twisting with one another excluding the at least one electric wire. The connection parts are connected to a frame of an underwater robot.

A flame-retardant flat electrical cable has a magnesium oxide dielectric layer. A plurality of spaced apart substantially parallel electrical conductors generally lie in the same plane and extend along the length of the cable. A dielectric layer is disposed on the top and/or bottom sides of the cable and covers the conductors. The dielectric layer comprises at least 90% magnesium oxide by weight. The dielectric layer exhibits good dielectric properties and is flame retardant without the use of halogens.
