Abstract: A shielded electrical cable includes a plurality of conductor sets. Each conductor set includes two insulated conductors. One of the conductor sets also includes a drain wire that generally lies in the plane of the two insulated conductors of the one conductor set. The conductor of each insulated conductor has a size that is not greater than 24 AWG. Each conductor set is substantially surrounded by a shield. The cable also includes first and second non-conductive polymeric layers disposed on opposite sides of the cable. The polymeric layers include cover portions and pinched portions arranged such that, in transverse cross section, the cover portions, in combination, substantially surround the plurality of the conductor sets, and the pinched portions, in combination, form pinched portions of the cable on each side of the plurality of the conductor sets.
