Abstract

The utility model relates to a central beam tube type armored optical cable for overhead laying, which is the further improvement to the optical cable. The utility model comprises a cable core, an armored layer and an outer sheath, wherein the armored layer is arranged between the cable core and the outer sheath. The utility model is characterized in that an inner sheath layer is arranged between the cable core and the armored layer. The utility model has the advantages that the inner sheath layer is additionally arranged in the armored layer of the central beam tube type optical cable; even when the outer sheath of the optical cable is destroyed by rodent animals, such as squirrels, mice, etc., owing to the function of the inner sheath layer, the optical cable adopting such structure can cause a central casing pipe to be prevented from being damaged by sunlight ultraviolet irradiation, the optical fiber in the central casing pipe in the cable core can obtain effective protection, the fiber protection performance of the optical cable can be further strengthened, and thus the long-term smooth operation of a communication line can be guaranteed. The central beam tube type armored optical cable has the advantages of simple structure and convenience for laying and installation, and is suitable for outdoor overhead laying.

Description

A kind of central beam tube type armouring optical cable
Technical field
The utility model relates to a kind of built on stilts laying with central beam tube type armouring optical cable, is the further improvement to this optical cable.
Background technology
Existing built on stilts laying with center tubular type armouring optical cable comprises that mainly cable part, armor and three parts of outermost oversheath constitute.Cable part comprises a center sleeve, is laid with optical fiber in the sleeve pipe, and center sleeve coats the metal armouring layer outward, does not establish other restrictive coating between center sleeve and metal armouring layer.In actual use, after in a single day the oversheath of this optical cable is broken by the teeth by rodents such as squirrel, mouse, sunshine will be by the gap and the breakage of armor, shine on the center sleeve, center sleeve can damage because of being subjected to ultraviolet irradiation and hyperthermia radiation for a long time, the destruction of center sleeve will directly influence the communication performance of center sleeve inner fiber, bring serious consequence to optical communication line.
Summary of the invention
Technical problem to be solved in the utility model is intended to the deficiency that exists at above-mentioned prior art and a kind of built on stilts laying with central beam tube type armouring optical cable is provided, this optical cable its sheath after oversheath is by local failure still can be resisted irradiation of sunlight and hyperthermia radiation, has the stronger cable that protects and protects fine function.
The utility model is that the technical scheme that problem adopted of the above-mentioned proposition of solution is: include cable core, armor and oversheath 1, armor is arranged between cable core and the oversheath, and its difference is to be provided with inner restrictive coating 4 between cable core and armor.
Press such scheme, described cable core comprises a center sleeve 7, is laid with optical fiber 9 and filling material water-proof material in the center sleeve; Described armor is the steel wire floor of circumferentially laying along cable core 3, or for wrapping up the steel belt layer 11 of cable core; Described inner restrictive coating 4 is made by the uvioresistant polyolefine material, has the function of ultraviolet radiation resisting.
The beneficial effects of the utility model are to have set up inner restrictive coating in the armor of central beam tube type optical cable; when adopting such cable configuration both to make the oversheath of optical cable be subjected to rodents such as squirrel, mouse to destroy; because the effect of inner restrictive coating; can make center sleeve avoid being subjected to solar ultraviolet irradiation and damage; optical fiber in the center sleeve in the cable core is effectively protected; the fine performance of protecting of optical cable has obtained further enhancing, thereby guarantees the long-term unimpeded operation of communication line.The utility model is simple in structure, and laying installation is convenient, is adapted to outdoor built on stilts laying.
Fig. 1 is the radial structure sectional view of an embodiment of the utility model.
Fig. 2 is the radial structure sectional view of another embodiment of the utility model.
Embodiment
Further specify embodiment of the present utility model below in conjunction with accompanying drawing.
First embodiment as shown in Figure 1, comprise cable core, armor and oversheath, cable core comprises a center sleeve 7, it can be made by PBT (polybutylene terephthalate) material, also can wait other material to make, be provided with optical fiber 9 in the sleeve pipe, in order to block water by PP (polypropylene), PC (polycarbonate), sleeve pipe contains material water-proof material 8, and material water-proof material is greasy for preventing water or water blocking yarn; Reinforcing element layer 6 is set outside center sleeve, and the reinforcing element layer is made up of tension stress materials such as aramid yarn, aramid belt, glass fiber yarn or glass fiber tapes; Can place water blocking layer 5 at reinforcing element layer 6 inner face or outside, water blocking layer is made of waterstop or water blocking yarn; Constitute cable core thus; Be inner restrictive coating 4 outside the cable core, inner restrictive coating is made of the uvioresistant polyolefine material, has the function of ultraviolet radiation resisting; Inner restrictive coating coats armor outward, the steel wire floor 3 that armor is circumferentially laid along cable core by one deck is formed, and the steel wire of steel wire floor relatively is evenly distributed on inner restrictive coating 4 peripheries, can place material water-proof material 10 around steel wire floor, material water-proof material is greasy for preventing water or water-proofing powder, wraps up last layer band 2 again; Outermost layer coats oversheath 1, and oversheath can be made of the uvioresistant polyolefine material.Armor in the present embodiment also can be made of plastics (FRP) the silk layer that glass fibre strengthens.
Second embodiment as shown in Figure 2, the main difference part of it and a last embodiment is that armor is that the steel belt layer 11 of parcel cable core is formed, steel belt layer is coated on outside the inner restrictive coating 4, in order to block water, is provided with water blocking layer 5 between steel belt layer and inner restrictive coating; Steel belt layer coats oversheath 1 outward, and oversheath and steel belt layer 11 are combined closely; 2~4 reinforcing elements 12 can be set in oversheath, and present embodiment both sides in oversheath become to be symmetrical arranged 2 reinforcing elements, and reinforcing element can be plastics (FRP) silk that steel wire or glass fibre strengthen.Other parts are identical with a last embodiment.
