Problems solved by technology

Usually, the effect of physical rodent prevention is better, but due to the high cost of armoring materials, low efficiency of optical cable production process, heavy weight of optical cable, and difficulty in construction with thick cable diameter, the cost of optical cable is increased.
However, chemical rodent control will cause environmental pollution due to the use of chemical materials, and will affect the health of operators during the production process, and the effect of rodent control is not ideal, so this method is rarely used now

Abstract

The invention discloses a novel rodent-resistant optical cable and a manufacturing process thereof. The rodent-resistant optical cable comprises an optical cable core, a steel-plastic composite belt, an inner sheath protecting layer, a glass fiber reinforcing belt and an outer sheath protecting layer. The manufacturing process of the rodent-resistant optical cable includes the steps: totally coating the optical cable core by the steel-plastic composite belt; extruding the inner sheath protecting layer outside the steel-plastic composite belt to form an inner optical cable; releasing the inner optical cable from a first pay-off reel, releasing the glass fiber reinforcing belt from a second pay-off reel, and coating the inner optical cable by a core tube die with a hole of a semi-extruded plastic extrusion die; extruding sheath materials outside the glass fiber reinforcing belt to form the outer sheath protecting layer. By combining physical rodent resistance with biological rodent resistance, rats are effectively resisted, and an optical cable structure and a machining process are simple and easy to implement. Compared with a traditional physical rodent-resistant optical cable, cost is reduced, and production efficiency is improved. Compared with a traditional chemical rodent-resistant optical cable, optical cable communication faults caused by rats are decreased.

Description

technical field [0001] The invention relates to the field of optical cable processing, in particular to a novel anti-rat optical cable and a manufacturing process thereof. Background technique [0002] With the strengthening of environmental protection in our country, the ecological environment has been greatly improved, and the squirrels in mountainous areas have increasingly damaged optical cables, affecting the normal communication. Rodent-proof optical cable has become a common type of optical cable in communication cables. Generally, there are two kinds of rodent-proof optical cables: one is physical rodent-proof and the other is chemical rodent-proof. [0003] Physical rodent protection usually adopts armor protection. The most effective method is thin round galvanized steel wire armor, followed by stainless steel tape armor, and nylon sheath protection, etc., so that rat bites cannot damage the internal optical cable, thus playing a role Anti-rodent effect; chemical...
