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.

The signal transmission cable includes: at least one pair of signal wires for transmitting a group of differential electronic signals, a first metal shielding film coated on a part of a surface of the at least one pair of signal wires; a second metal shielding film opposite to the first metal shielding film and coated on a part of a surface of the at least one pair of signal wires; and a first insulation film by which the first metal shielding film and the second metal shielding film are secured to the surface of the pair of signal wires. The first metal shielding film and the second metal shielding film are collectively coated on the entire surface of the at least one pair of signal wires, and the second metal shielding film partially overlaps the first metal shielding film.

An electric cable, in particular a data cable, has a transmission core which is surrounded by a shield and concentrically surrounded by a sheath that includes an outer layer made of an electrically insulating plastic material and a second layer underneath that is made of a semiconducting material. The semiconducting material primary purpose is to divert interference currents.

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.
