Abstract: An improved aluminum alloy armoured cable wrap has been produced which permits the use of less aluminum alloy in the cable wrap thereby achieving lighter construction, while meeting or exceeding strength and flexibility requirements. The armoured cable wrap is made from aluminum alloy strip material formed of an aluminum alloy containing about 2.8-3.5 percent by weight Mg, about 0.25-0.70 percent by weight Mn and about 0.15-0.35 percent by weight Cr. Up to 0.5 percent by weight of Cu may also be added. The strip material is heat treated preferably to an Ultimate Tensile Strength of at least 265 MPa.

Abstract: A metal-free optical cable has a cable core with a plurality of optical fibers in a sheath, which is surrounded by a carrier member in the form of at least one ply of a high-strength film material. The improvement characterized by the filament material being held together by an externally applied winding of a filament forming an armoring layer with the filament being of a shorter length of lay than the filament material for the carrier member and being of a material exhibiting electrical properties that are substantially the same as the material of the filament forming the carrier member.

Abstract: An armored cable and a method of manufacturing an armored cable, said cable having a helically wrapped zinc-plated steel armor. The steel armor band has zinc protective layer on its two sides, and uncoated edges, to reduce manufacturing costs and improve cathodic protection. The zinc protective layer thereby comprises a first layer portion consisting of a zinc-iron alloy and a second layer portion, on top of said first layer portion consisting of essentially pure unalloyed zinc and having a thickness of at least 90% of the total layer thickness.
