Abstract

The utility model discloses a low temperature resistant anti-fracture ADSS optical cable, which comprises a central tensile unit, an optical fiber unit intertwisted layer, a wrapping layer, an inner layer protective sleeve, an armor layer, an outer layer protective sleeve and a convex body, the optical fiber unit intertwisted layer is arranged outside the central tensile unit, the wrapping layer is arranged outside the optical fiber unit intertwisted layer, and the outer layer protective sleeve is arranged outside the outer layer protective sleeve. According to the ADSS optical cable, the central tensile unit provides support for the optical fiber unit stranded layer, the bending resistance of the ADSS optical cable is improved, the overall mechanical strength is further improved through the arrangement of the armor layer, and the thickness of the outer protective sleeve is relatively improved through the arrangement of the convex body, so that the ADSS optical cable has a certain bending resistance effect, and the service life of the ADSS optical cable is prolonged. According to the anti-icing ADSS optical cable, the inner layer protection sleeve, the armor layer and the outer layer protection sleeve are matched, excellent low temperature resistance is provided for the ADSS optical cable, the environmental adaptability is improved, the service life is prolonged, the convex bodies effectively separate the icing from the middle part, the icing is not prone to staying on the ADSS optical cable, and the anti-icing performance is further improved.
