Non-metal yarn inlaid ratproof optical cable and manufacturing method thereof

Abstract

The invention discloses a non-metal yarn inlaid ratproof optical cable and a manufacturing method thereof. The optical cable comprises an optical cable outer sheath and an optical cable inner sheath.A stainless steel belt armor layer is arranged in the inner sheath. Glass fiber yarn is inlaid in the outer sheath. The outer sheath and the inner sheath are separated by a water blocking layer. A cable core formed by SZ stranding a central reinforcing member and a PBT loose sleeve is arranged in the stainless steel belt armor layer. The PBT loose sleeve contains at least two or more colored optical fibers. The colored optical fibers are surrounded by a sleeve filler. The method comprises the steps of optical fiber coloring, cable core manufacturing through PBT optical fiber oil-filled loose sleeve stranding, stainless steel belt armor polyethylene inner sheath manufacturing, water blocking belt longitudinal wrapping, water-blocking glass fiber yarn manufacturing and glass fiber yarn inlaying in the polyethylene outer sheath, namely non-metal yarn inlaid ratproof optical cable molding. The optical cable has the advantages of good bending performance and light weight, is soft, and is prevented from the damage of rats and environmental erosion. The structure of the optical cable is stable during the service life thereof.

Description

technical field [0001] The invention belongs to the technical field of optical cable manufacturing, and relates to a non-metal yarn inlaid anti-rat optical cable and a manufacturing method thereof. Background technique [0002] With the continuous development of optical communication technology, the laying of optical cables is becoming more and more widely used. Therefore, optical cables are often used in various complex environments. In many areas, there are rodents such as voles, gophers, and squirrels. The operation of the line caused great harm. Therefore, the research and development of anti-rat optical cable becomes inevitable. There are many anti-rodent methods for traditional optical cables. Adding chemical reagents such as capsicum to the sheath material, or using steel tape, steel wire multi-layer armor, etc., have obvious defects. Because, as time goes by, the chemical anti-rodent agent added in the sheath migrates and volatilizes, and it is difficult to ensure ...

AI Technical Summary

Problems solved by technology

Because, as time goes by, the chemical anti-rodent agent added in the sheath migrates and volatilizes, and it is difficult to ensure the protective effect and life cycle of the optical cable. In addition, after the outer sheath of the multi-layer armored protective optical cable is damaged, the armor layer It will slowly corrode due to environmental erosion, causing the cable core to be exposed, and eventually lose the anti-rat effect, and the weight and outer diameter of the optical cable itself are much higher than conventional optical cables, and the flexibility is poor, which brings a lot of inconvenience to manufacturing and construction.
