An electromagnetic shielding film for a cable, which relates to the field of wire manufacturing, for use in resolving the problem of easiness of break of the existing electromagnetic shielding film and the great consumption of time and power in the preparation process. The electromagnetic shielding film comprises a first metal layer (11,21,31,41), a conductive layer (12,22,32,42), and a protective film (13,23,33,43). The first metal layer covers the outer part of a conductor of a cable, and is used for shielding electromagnetic interference and is used as a medium. The conductive layer is disposed on the first metal layer, and is used for shielding electromagnetic interference, and the conductive layer comprises a curing agent, metal particles and polyurethane for carrying the metal particles. The protective film is disposed on the conductive layer and protects the electromagnetic shielding film.

A shielded electrical ribbon cable includes adjacent first and second longitudinal conductor sets where each conductor set includes two or more insulated conductors. The first conductor set also includes a ground conductor that generally lies in the plane of the insulated conductors of the first conductor set. At least 90% of the periphery of each conductor set is encompassed by a shielding film. First and second non-conductive polymeric films are disposed on opposite sides of the cable and form cover portions substantially surrounding each conductor set, and pinched portions on each side of each conductor set. When the cable is laid flat, the distance between the center of the ground conductor of the first conductor set and the center of the nearest insulated conductor of the second conductor set is 1, the center-to-center spacing of the insulated conductors of the second conductor set is 2, and 1/2 is greater than 0.7.

A cable is provided for power transmission or communication. The cable has a core unit with at least one conductor and an insulating layer surrounding each conductor. A first shielding layer surrounds the core unit and is formed of a polymer-carbon composite in which carbon-based particles are dispersed in a matrix of a polymer material. The first shielding layer has an electrical resistance of 10 .Math.m or less. A metal-based second shielding layer surrounds the first shielding layer.

A cable structure and a manufacturing method thereof are provided. The cable structure includes a transmission component and a protection component. The transmission component includes at least one first intermedium unit, and the least one first intermedium unit includes at least one first transmission cable and a first barrier layer covering the at least one first transmission cable. The protection component includes at least one shielding layer covering the at least one first intermedium unit and an insulating layer covering the at least one shielding layer. The at least one shielding layer includes a metal foil layer covering the at least one first intermedium unit and at least one conducting layer formed on a surface of the metal foil layer.

An electrical cable includes a conductor assembly having a first conductor, a second conductor and an insulator surrounding the first conductor and the second conductor. The insulator has an outer surface having an RMS roughness of less than 1.0 micrometers. A cable shield provides electrical shielding for the first and second conductors and has a metallized conductive layer on the outer surface of the insulator. A method of manufacturing an electrical cable includes feeding a first conductor and a second conductor to a core extruder, extruding an insulator around the first and second conductors at the core extruder, heating an outer surface of the insulator to lower a roughness profile of the outer surface, and directly apply a conductive layer to the outer surface of the insulator.

A cable is specified, specifically for a signal line, which extends in a longitudinal direction and which includes an inner conductor and also an outer conductor. Between the inner conductor and the outer conductor there is formed an insulating material which surrounds the inner conductor and which has a surface that has been at least partially carbonized. Furthermore, a production method for such a line is specified.

An electrical cable includes a conductor assembly having a first conductor, a second conductor and an insulator surrounding the first conductor and the second conductor. The insulator has an outer surface and extends along a longitudinal axis for a length of the electrical cable. The conductor assembly has a coating layer on the outer surface of the insulator being conductive defining an inner electrical shield of the electrical cable. A cable shield is wrapped around the conductor assembly and has an inner edge and an outer edge. The outer edge is wrapped over the inner edge to form a flap covering the inner edge and extending along the longitudinal axis. The cable shield engages the inner electrical shield and forms an outer electrical shield exterior of the inner electrical shield.
