Abstract: Ribbon cables have lower capacitance, higher impedance, and faster propagation velocities with microporous fibril thermoplastic dielectric insulation, because they have great amounts of air adjacent to the conductors and the improved electrical performance is due in part to the improved crush resistance. Crystallizable thermoplastic polymers having good fibril structure and crush resistance include polyolefins such as polypropylene and polymethylpentene. A layer of metal adhered to the dielectric insulation provides improved transmission line properties.
