Rainwater pipeline cable

Abstract

The invention discloses a rainwater pipeline cable and relates to the technical field of an optical cable. A plurality of plastic loose tubes are stranded around a center reinforcement member; each plastic loose tube is internally equipped with optical fibers and filled with fiber paste; an aluminum plastic compound tape is wrapped outside the plastic loose tubes; a polyethylene protection jacket is wrapped outside the aluminum plastic compound tape; and a polyethylene sheath is wrapped outside the polyethylene protection jacket. The cable is combined with an ADSS aramid reinforcement member and a specially-produced ratproof and anti-termite outer sheath, so that tension resistance and biological damage preventing performance of the rainwater pipeline cable are enhanced; the good self-supporting tensile property of the rainwater pipeline cable allows the fibers not to be damaged in the traction and installation process, thereby ensuring integrity of communication performance; and corrosion resistance and ratproof and anti-termite functions of the cable allow the cable not to be torn or damaged by rats and termites under a dark underground pipeline, nor easy to be corroded by chemicals, thereby ensuring normal communication of the fibers and ensuring service life of the fiber cable.

Description

[0001] Technical field: [0002] The invention relates to a rainwater pipeline optical cable, which belongs to the technical field of optical cables. [0003] Background technique: [0004] All kinds of wiring in today's cities are dense, and overhead and buried are the mainstream wiring methods. However, with the increase of various wiring, the wiring is dense and tends to be saturated. In order to alleviate the pressure on urban wiring resources, rainwater pipes have not been fully developed and utilized as It is a supplementary means when other laying methods cannot meet the needs of line installation. [0005] With the rapid development of metropolitan area network and access network, urban network management hole resources are becoming increasingly tight, the management of urban municipal construction is gradually improving, and the approval procedures for excavation and laying are becoming increasingly strict. The rainwater pipeline network that has not been fully develop...

AI Technical Summary

Problems solved by technology

[0006] The environment of rainwater pipelines is usually relatively humid and dark, and conventional optical cables will be damaged due to long-term exposure to this relatively poor environment, and the existing conventional pipeline optical cables have poor corrosion resistance and anti-rat and termite-proof capabilities. Frequent replacement is required, resulting in a certain waste of resources. Therefore, it is urgent to design a new type of rainwater pipeline optical cable with strong tensile properties, improved anti-rat and termite-proof capabilities, and long service life.
