Abstract
The utility model relates to a salt-corrosion-resistant torsion-resistant separated-screen communication cable for offshore wind power. Each insulating core is formed by uniformly extruding a salt-corrosion-resistant torsion-resistant rubber insulating layer from a stranded copper conductor, the insulating cores are stranded pairwise to form twisted cable pairs, flame-retardant non-hygroscopic fiber filling cores are filled into gap of each twisted cable pair, and each twisted cable pair is wrapped a copper-foil polyester composite shielding layer to form a twisted group; the multiple twisted groups are stranded to form a cable core; a low-strength non-woven-fabric longitudinal wrapping wraps the cable core; and a sheath is extruded from the low-strength non-woven-fabric longitudinal wrapping. The appearance of the low-strength non-woven-fabric longitudinal wrapping is matched with that of the insulating cores, so that gap between the low-strength non-woven-fabric longitudinal wrapping and the insulating cores is eliminated, flame is prevented from spreading inwards during combustion, and resistance to dipping of humidity can be enhanced; and at the same time the low-strength non-woven-fabric longitudinal wrapping ensures that the sheath is not adhesive to the insulating cores, so that when the sheath is stripped during construction, the insulating cores are not damaged.
