Abstract:
An electrical cable, comprising:a first ribbon conductor assembly including, a first ribbon conductor having an approximately rectangular cross-section transverse to a longitudinal axis of said cable, a first dielectric jacket enclosing said first ribbon conductor, said first jacket having a cross-sectional area greater than a cross-sectional area of said first ribbon conductor transverse to said longitudinal axis, said first jacket positioned to form an air gap substantially surrounding said ribbon conductor, and a first electrically-conductive shield adjacent said first jacket; a second ribbon conductor assembly including, a second ribbon conductor having an approximately rectangular cross-section transverse to a longitudinal axis of said cable, a second dielectric jacket enclosing said second ribbon conductor, said second jacket having a cross-sectional area greater than a cross-sectional area of said ribbon conductor transverse to said longitudinal axis, said second jacket positioned to form an air gap substantially surrounding said ribbon conductor, and a second electrically-conductive shield adjacent said second jacket, said first and second electrical conductor assemblies being disposed adjacent to one another, each of said first and second ribbon conductors having a width and a thickness, said width being at least approximately ten times said thickness, wherein said first, second, and third ribbon conductors are made of electrically-conducting materials; and a ground conductor assembly including a third ribbon conductor having an approximately rectangular cross-section transverse to a longitudinal axis of said electrical cable, said third ribbon conductor made of an electrically-conducting material; a third dielectric jacket enclosing said third ribbon conductor, said third jacket having a cross-sectional area greater than a cross-sectional area of said third ribbon conductor transverse to said longitudinal axis, said third jacket positioned to form an air gap on each side of said third ribbon conductor; and a third electrically-conductive shield adjacent said third jacket, said ground conductor assembly being disposed approximately parallel to said longitudinal axis.
