Abstract
A cable comprises a plurality of insulated conductors enclosed in a corrugated metallic shield jacketed with a plastic material. As a corrugated metallic tape is wrapped longitudinally about the core to form the shield, overlapping longitudinal edge portions of the shield are intentionally spaced apart radially. When the plastic jacket is extruded over the shield, a portion of the plastic material extends between the overlapped but spaced apart longitudinal edge portions. This prevents lock-in of the corrugations along the overlapped edge portions and provides the cable with an additional degree of freedom of movement so that the cable can withstand placement stresses caused by sharp radius bending during installation without shield separation or cracking.
