A flexible cable which includes a Faraday shield sheath formed of a high permeability ferrous alloy filled matrix binder of conductive elastomers, to provide electromagnetic interference EMI isolation between the ambient environment about the cable and a conductor line or lines within the cable, or vice versa. The flexible cable shield may be embodied as a flexible electrical cable that comprises at least the elements of a single electrically conductive core, an insulator sheath, and a Faraday shield sheath, and may be manufactured as a single extruded cable. The conductive property of the matrix binder provides isotropic conductivity within the sheath, which is requisite of an effective Faraday shield. In the alternative, the flexible cable shield may be embodied as a multiple conductor flexible electrical cable that comprises two or more inner cables as described, and a pile of alternating insulator and a Faraday shield sheaths about the inner cables.
