Abstract: A flat electrical cable extends longitudinally along a length of the cable. The flat electrical cable includes a plurality of conductor sets extending along the length of the cable. Each conductor set includes one or more insulated electrical conductors. Each insulated conductor includes a central conductor surrounded by a first dielectric material. The plurality of conductor sets includes a middle conductor set disposed between two other conductor sets and an edge conductor set disposed proximal to a longitudinal edge of the cable. The first dielectric material of each insulated conductor of the edge, but not the middle, conductor set includes an intumescent flame retardant material.

Abstract: A cable includes one or more conductor sets, one or more dielectric unitary blocks or reservoirs, first and second conductive shielding films disposed on opposite first and second sides of the conductor sets and the dielectric blocks or reservoirs, and an adhesive layer. The shielding films include cover portions and pinched portions arranged such that, in cross-section, the cover portions of the shielding films in combination substantially surround each conductor set and each unitary block or reservoir, and the pinched portions of the shielding films in combination form pinched portions of the cable on each side of the conductor set and on at least one side of the unitary block or the reservoir. The adhesive layer bonds the first shielding film to the second shielding film in the pinched portions of the cable.

Abstract: A flat electrical cable is described. The cable includes a plurality of equally spaced substantially parallel electrical conductors lying in a same plane and extending along the length of the cable. Each conductor has a same diameter D. The cable further includes a common unitary electrically insulating layer encapsulating the plurality of conductors. The insulating layer includes a plurality of cover portions where each cover portion is concentric with a corresponding conductor and has a radial thickness t. t/D is in a range from about 0.50 to about 1.25.

Abstract: 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 σ1, the center-to-center spacing of the insulated conductors of the second conductor set is σ2, and σ1/σ2 is greater than 0.7.
