  • Patent number: 4729629
    Abstract: A bonded sheath cable is disclosed of the type having a metallic shield wrapped around a cable core so as to form a longitudinal seam. A jelly-like lubricant overlays the metallic shield seam area and serves to decouple the bond between the metallic shield and an outer plastic jacket. The lubricant allows for relative movement between the longitudinal ends of the metallic shield and the overlying jacket layer without damaging the jacket layer if the bond between the overlapping ends of the metallic shield is broken and the cable twisted during installation or in some other manner.
