ABSTRACT:
An improved shielding member and electric cable constructions which utilize this shielding member are described, the design of the shielding member allowing two cable circuits, each consisting of one or more conductors to be wrapped in and electrically isolated by a single shielding member. The shielding member comprises an elongated ribbon of insulating material and a pair of elongated foil strips arranged in a parallel relationship with the ribbon, the foil strips being bonded to opposite sides of the ribbon and each of the foil strips having an elongated edge generally in alignment with opposite elongated edges of the ribbon. The shielding member is wound in a generally S-shaped configuration forming two envelopes, each of the cable circuits being encased in, and electrically isolated by, one of the envelopes.
