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.

An optoelectronic device comprises a plurality of layer segments, in particular intermediate layer segments, arranged between a cover layer and a carrier layer. At least one optoelectronic component is arranged on at least one of the plurality of layer segments and a first and a second layer segment of the plurality of the layer segments are overlapping each other along a first direction each forming a respective boundary region. The first layer segment comprises at least one first contact pad and the second layer segment comprises at least one second contact pad, wherein the at least one first and second contact pad are arranged in the respective boundary region facing each other and being mechanically and electrically connected. The at least one first and second contact pad each comprises a plurality of nanowires which are at least partially made of conductive material such as for example copper, gold, or nickel.

The present application discloses a winding wire, comprising: a plurality of wires each comprising a core and a coating covering the core; and an insulation layer wrapping around the plurality of wires, wherein the plurality of wires are twisted spirally at least thirty-three times in a length of one meter, and wherein the plurality of wires twisted spirally are disposed in an X-axis direction of the insulating layer, and the insulating layer continuously wraps around the plurality of wires twisted spirally along a Y-axis direction perpendicular to the X-axis direction until a number of layers covering the plurality of wires twisted spirally is at least three.

An insulated wire having at least one layer of coating of the wire, comprising a thermosetting resin layer, at the outer periphery of a conductor, wherein the thermosetting resin layer is comprised of thermosetting resin layers having a laminated structure formed by coating and baking a thermosetting resin varnish; and wherein, in said laminated structure, an innermost layer having contact with the conductor comprises a thermosetting resin having an imide bond and is a layer having an average thickness of more than 5 μm and 10 μm or less; a method of producing the insulated wire; a coil; a rotating electrical machine; and an electrical or electronic equipment.

Provided is a method of manufacturing a cable, including the following steps of: (a) providing two lateral sides of an inner layer that enclose two sides of a first conductor along a circumferential direction and an opposite direction of the circumferential direction respectively and join to each other, such that the inner layer covers an outer surface of the first conductor; and (b) providing an outer layer that continuously wraps around an outer surface of the inner layer along the circumferential direction and a length direction of the first conductor, thereby forming the cable. Provided is also a cable manufactured by the above method.
