Problems solved by technology

[0003] Existing self-supporting optical cables are generally formed in one piece, and stranded steel wires are used as the reinforcement of the suspension part to realize self-supporting. Although the function of greater bearing capacity has been achieved, the sheath outside the stranded steel wires is extremely rough. , the performance of the sheath of the optical cable is extremely unsatisfactory; to achieve smoothness, the thickness of the sheath must be greatly increased, which increases the weight and cost of the optical cable and shortens the span of the optical cable

Abstract

The invention discloses a self-supporting optical cable with a marking strip. The self-supporting optical cable comprises an outer sheath; an installation cavity is arranged inside the outer sheath; aprotection layer is arranged at the inner wall of the installation cavity; and three separation bars are arranged inside the protection layer in an annular manner to form a triangular structure and each two adjacent separation bars are connected by a connection post abutted against the protection layer. A reinforced cavity is formed among the three separation bars; and a central reinforced rope is arranged in the reinforced cavity. Placing cavities are formed between the separation bars and the protection layer; and wire cores are arranged in the placing cavities respectively. A mounting surface is arranged at the lower end of the outer sheath; and a marking strip is arranged on the mounting surface. Two suspension wire protection sleeves are arranged at the upper end of the outer sheath;reinforcement elements are arranged inside the suspension wire protection sleeves; and a basket screw is arranged between the two suspension wire protection sleeves. The self-supporting optical cablehaving a simple structure is operated conveniently; the self weight of the optical cable is reduced; the proper span is extended; and the elf-supporting optical cable with the identification functionis suitable for popularization.

Description

technical field [0001] The invention relates to the technical field of cables, in particular to a self-supporting optical cable with identification strips. Background technique [0002] Most of the self-supporting optical cables are used for overhead laying. Due to their excellent load-bearing performance, the cables can be laid without additional steel strands for support. Usually, the cables are fixed on the clamps at the towers. That is, it can be placed freely between adjacent towers. However, with the rapid development of the communication industry, the number of cables between poles and towers increases sharply, which brings great trouble to maintenance because it is not easy to distinguish. For this reason, a large amount of researches have been carried out at home and abroad. The announcement number is CN202196211U, and the name is 8-shaped self-supporting aerial optical cable with color stripes on the surface. It includes an optical cable core and an outer sheath. ...
