ABSTRACT:
A shielded flat electrical cable is formed of a plurality of twisted pairs of conductors. Individual conductors of each conductor pair are twisted about each other for at least one portion of their mutual length. The conductors are laminated to a film to maintain predetermined spacing and the electrical parameters of the cable. In a preferred embodiment, the shielding comprises a wider and a narrower tape, each having a conductive layer and an insulating strength-giving layer. The tapes are disposed on opposite sides of the core of the cable. The wider tape wraps around the edges of the core and overlies portions of the narrower tape so as to make electrical contact therewith, avoiding a slot effect.
