Abstract

The invention relates to the technical field of cables and discloses a nonmetal self-supporting type optical cable which comprises a cable core, a protection layer, an outer sheath, a reinforcing partand a suspension wire protection layer, wherein the cable core is covered by the protection layer and the outer sheath, the reinforcing part is prepared from a fiber reinforced composite material, and the suspension wire protection layer is covered by the reinforcing part; a plurality of noctilucence marking strips with the different color from the suspension wire protection layer and a rib for connecting the suspension wire protection layer with the outer sheath are arranged on the suspension wire protection layer; the suspension wire protection layer, the outer sheath and the rib are prepared from a low-smoke zero-halogen material and integrally formed; the cable core comprises a central reinforcing part and a plurality of tightening sleeves, the central reinforcing part is arranged inthe center of the cable core, the plurality of tightening sleeves are arranged at the periphery of the central reinforcing part, an inner core is arranged in each tightening pipe, the inner core comprises at least one optical fiber, and water stopping gauze is arranged among the tightening sleeves and the central reinforcing part. By means of the structure, the nonmetal self-supporting type optical fiber disclosed by the invention has the advantages of simple and compact structure, light weight, convenience in recognition and maintenance and good compression resistance and tensile property; furthermore, interference of electromagnetic signals is eliminated; thus, the nonmetal self-supporting type optical fiber is suitable for multi-scene indoor and outdoor laying and has a wide applicationprospect.

Description

technical field [0001] The invention relates to the technical field of cables, in particular to a non-metallic self-supporting optical cable. Background technique [0002] With the further optimization or development in the field of optical fiber manufacturing process and manufacturing equipment, the proportion of optical fiber in the total signal and communication cables is rapidly increasing. Since the self-supporting optical cable does not need to erect steel strands and installation hooks when laying overhead, it has the characteristics of simple laying and low construction cost, and is widely used in various environments. However, the application scenarios of self-supporting optical cables are currently limited. Load-bearing suspension wires or steel strands hinder the application of self-supporting optical cables in high-voltage cable areas. Contents of the invention [0003] The purpose of the present invention is to overcome the above problems in the prior art, an...
