Problems solved by technology

At present, anti-biological optical cables are generally armored with stainless steel tape. The stainless steel tape can not only prevent rodents from biting through the optical cable, but also prevent damage caused by rust when the outer skin is damaged. It can solve the problem of biological bites very well, but Stainless steel tape as an armor layer increases the risk of lightning strikes, and for overhead optical cables, lightning protection is an important consideration
[0004] The traditional optical cable is filled with ointment in the casing and outside the cable core to block water. The advantage is that it can prevent water and moisture from entering the cable. The disadvantage is that the filling of ointment not only brings inconvenience to production, but also It also greatly increases the weight of the optical cable. Once the optical cable is broken, the smell of the ointment will attract rats such as squirrels to bite it, thereby aggravating the damage of the optical cable.
[0005] Most of the cores of existing optical cables adopt a conventional layer-stranded structure, and the loose tube is twisted around the central strength member, which increases the weight of the optical cable

Embodiment 1

[0032]Such asfigure 1 withFigure 5 As shown, a 8-glyph antifole is engaged, including the main cable core and the hanging cable core. The main cable core is a done-free reinforcing layer stranded, the main cable core includes fiber 1, water supply yarn 2 , All-handed loose sleeve 3, water cover 4, inner sheath 5, FRP armor 6 and outer sheath 7, several root fiber 1 and water yarn 2 Loosen the lamination of the lamination 3 by the inner layer, forming fiber core, full-drying loose water (water yarn 2), full dry The structure helps to reduce the cable weight, according to the number of cores, 3 fiber cores and filled rings can be used to twisted each other, filling several root resistant yarn 2, not using the center to reinforcement, and the cable out of the cable Waterproof belt 4, the water-water belt 4 uses the polyethylene material to form the inner sheath 5, the outer cover 5 outside the outer coated FRP armor layer 6, the FRP armor layer 6 uses flat circular rod-shaped fiber rei...

Embodiment 2

[0035]Such asfigure 2 withFigure 5 As shown, a figure-eight anti-biological bite optical cable includes a main cable core and a suspension cable core. The main cable core is a stranded structure without a central reinforcement. The main cable core includes an optical fiber 1, a water blocking yarn 2 , Full dry loose tube 3, water blocking tape 4 wrapped around the outside of the full dry loose tube 3, inner sheath 5, FRP armor layer 6 and outer sheath 7, several optical fibers 1 and water blocking yarn 2 It is loosely wrapped in the loose tube 3 through the inner layer molding process to form an optical fiber core. The fully dry loose tube 3 is equipped with an optical fiber 1 and a dry water blocking material (water blocking yarn 2), fully dry The structure helps to reduce the weight of the cable. According to the requirements of the number of cores, 3 optical fiber cores and filling ropes can be used to twist each other around the water blocking yarn 2 to form a cable, and several...

Embodiment 3

[0039]Such asimage 3 withFigure 6 As shown, a figure 8 anti-biological biting optical cable includes a main cable core and a suspension cable core. The main cable core is a central tube structure. The main cable core includes an optical fiber 1, a water blocking yarn 2, and a fully dry type. Loose tube 3, water blocking tape 4, FRP armor layer 6 and outer sheath 7, covering the outside of fully dry loose tube 3, several optical fibers 1 and water blocking yarn 2 are covered by the inner layer one-time coating process Loosely wrapped in the loose tube 3, the loose tube 3 is wrapped with a water blocking tape 4, and the water blocking tape 4 is protected by FRP armor to form an FRP armor layer 6. The FRP armor layer 6 uses oblate rod-shaped fibers Reinforced plastic FRP material is used for armoring. After armoring, the outer sheath 7 is formed by a polyethylene material sheath. A suspension cable core is set above the main cable core. The suspension cable core includes a suspension w...

Abstract

The invention discloses a 8-shaped biological bite prevention optical cable, wherein the cross section of the 8-shaped biological bite prevention optical cable is 8-shaped; the 8-shaped biological bite prevention optical cable comprises a main cable core and a hanging cable core, wherein the main cable core and the hanging cable core are arranged in parallel and connected into a whole through a hanging belt, the main cable core is of a layer-stranded structure or a central tube structure without a central reinforcing piece, and the main cable core comprises optical fiber cores; the plurality of optical fiber cores are mutually twisted to form a cable, a water-blocking tape is wrapped outside the optical fiber cores, an FRP armor layer is wrapped outside the water-blocking tape, an outer sheath is wrapped outside the FRP armor layer, and an inner sheath is selectively arranged between the water-blocking tape and the FRP armor layer. According to the 8-shaped biological bite prevention optical cable provided by the invention, a full-dry water blocking mode is adopted for blocking water, round or flat rod-shaped fiber reinforced plastic FRP is used for armoring, the effects of preventing biological bite and improving the mechanical properties such as stretching and flattening of the optical cable are achieved, and the whole 8-shaped biological bite prevention optical cable is of an all-dielectric non-metal structure, free of metal conductors, and lightning-proof and electricity-proof. The cable can be applied to overhead laying in mountain forest regions and power scenes, andthe communication stability is guaranteed.

Description

Technical field[0001]The present invention belongs to the technical field of communication fiber optic cables, and more particularly to an 8-glyph antifalent engagement cable.Background technique[0002]As information demand continues to grow, fiber optic communication is widely used as a speed of the fastest and transmission quality. In the case of landslings, rural and other regions, the fiber optic cable is often used by birds, and the mouse, squirrel is often engaged in mice, which leads to communication interruption, especially the overhead layout of the forest area, and squirrels are attracted by the smell of the cable sheath and internal ointment. . Once the cable is destroyed, the loss of communication interruption and maintenance is unatristent.[0003]At present, in the optical cable communication, according to the laying method, the cable can be divided into three types of overhead, direct buried and pipelines. In the overhead cable, according to the gender, it can be divided...
