FRP (fiber reinforce plastic) rod armored nonmetal rat-proof optical cable and manufacture process thereof

Abstract

The invention discloses an FRP (fiber reinforce plastic) rod armored nonmetal rat-proof optical cable and a manufacture process thereof. The FRP rod armored nonmetal rat-proof optical cable includes an optical cable core, an FRP rod armored layer and an outer protective layer, wherein the optical cable core is wrapped with the FRP rod armored layer; and the FRP rod armored layer is wrapped with the outer protective layer. The manufacture process of the FRP rod armored nonmetal rat-proof optical cable includes the following steps that: FRP rods are stranded at the exterior of the optical cable core in an armoring manner through adopting an SZ stranding mode, so that the optical cable core can be wrapped with and protected by the FRP rods; when the armoring and wrapping of the FRP rods are carried out, fastening yarns are adopted to fasten the FRP rods and fix the FRP rods at the exterior of the optical cable core; the FRP rod armored optical cable is released from a pay-off rack, and is built in an extrusion type module; and the outer protective layer is formed through extrusion. The FRP (fiber reinforce plastic) rod armored nonmetal rat-proof optical cable of the invention is relatively simple in structure and processing technology, and can be realized with easiness. Compared with a traditional metal armored physical rat-proof optical cable, the FRP rod armored nonmetal rat-proof optical cable has the advantages of decreased cost, improved production efficiency and prolonged service life, and can meet the requirements of existing application environments and decrease optical cable communication failure caused by rats.

Description

technical field [0001] The invention relates to the field of optical cable processing, in particular to an FRP rod armored non-metal 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. Usually the more effective anti-rat optical cable is to prevent rats through physical protection. [0003] Physical rodent protection usually adopts armored protection, the most effective method is thin round galvanized steel wire armor, and metal armored rodent protection with stainless steel tape armor, followed by the use of non-metallic fiberglass yarn or non-metallic fiberglass tape Non-metallic armored rodent protection su...

AI Technical Summary

Problems solved by technology

Although the effect of metal rodent protection is better, the cost is high, the production efficiency is low, and it does not have the performance of lightning protection; while the traditional non-metallic armored rodent protection is not only costly but also not ideal for rodent protection. severe area use
