Abstract
The utility model relates to a salt-corrosion-resistant torsion-resistant bulk-shielding 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 multiple twisted cable pairs are stranded to form a cable core; and a low-strength non-woven-fabric longitudinal wrapping, an inner sheath, a copper-foil polyester composite shielding layer and an oversheath successively wrap the cable core from inside to outside. The appearance of the low-strength non-woven-fabric longitudinal wrapping is completely 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 inner sheath is not adhesive to the insulating cores, so that when the inner sheath is stripped during construction, the insulating cores are not damaged.
