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 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: An electrical cable (1000) including a plurality of substantially parallel insulated conductors (100) is described. Each insulated conductor (100) includes an electrically conductive inner conductor (200) co-extensive and covered with an insulating layer (300). At least a portion of a periphery of each insulated conductor (100) may be encompassed by a substantially co-extensive electrically conductive shield (400). For each insulated conductor (100), portions of the insulating layer (300) are removed from the top side (1200) of the cable (1000) to expose a portion of the inner conductor (200) of the insulated conductor (100). The insulated conductor (100) is adapted to mate with an electrically conductive mating conductor (500) at the exposed portion (210) of the inner conductor (200).
