OPGW tau siv ntau thiab ntau dua, tab sis nws lub neej kev pab cuam kuj yog ib qho kev txhawj xeeb ntawm txhua tus.Yog tias koj xav tau lub neej ntev ntawm cov khoom siv kho qhov muag, koj yuav tsum tau them sai sai rau peb cov ntsiab lus hauv qab no:
1. Loose Tube Loj
Kev cuam tshuam ntawm qhov loj ntawm lub raj xoob ntawm lub neej ntawm OPGW cable kuj tseem cuam tshuam txog kev ntxhov siab induction.Yog tias qhov loj me me dhau lawm, vim qhov kub hloov pauv, kev ntxhov siab ntawm cov khoom siv, thiab kev sib cuam tshuam ntawm cov khoom siv thiab cov khoom siv kho qhov muag, qhov kev ntxhov siab ntawm cov khoom siv kho qhov muag tsis tuaj yeem txo qis, uas yuav ua rau kom poob qis hauv lub neej ntawm OPGW optical cable thiab ua rau kev laus.
2. Kev Npaj Tshuaj Txhuam Hniav
Fiber paste yog cov khoom oily ntawm OPGW optical cable.Nws yog ib qho kev sib xyaw ua ke raws li cov roj ntxhia lossis cov roj muaj pes tsawg leeg, uas muaj cov txiaj ntsig ntawm kev thaiv cov dej vapor thiab buffering ntawm qhov kho qhov muag cable.Kev ua haujlwm ntawm cov tshuaj fiber ntau yog ntsuas los ntawm kev ntsuas lub sijhawm oxidation induction ntawm cov tshuaj pleev.Qhov nce hauv cov kua qaub ntawm cov tshuaj pleev tom qab oxidation tuaj yeem ua rau muaj kev nce hauv hydrogen evolution.Tom qab cov tshuaj pleev yog oxidized, nws yuav cuam tshuam rau kev ruaj ntseg ntawm cov qauv kho qhov muag, ua rau muaj kev ntxhov siab.Nyob rau hauv txoj kev no, OPGW kho qhov muag cable yuav raug kev txom nyem Thaum muaj kev ntxhov siab, cov nyhuv buffering ntawm fiber ntau muab tshuaj txhuam rau ntawm qhov muag cable tsis muaj zog, yog li txo qhov kev nyab xeeb ntawm OPGW optical cable.Kev sib cuag ncaj qha ntawm fiber ntau muab tshuaj txhuam thiab OPGW cable yog qhov ua rau ncaj qha ntawm kev ua haujlwm ntawm fiber ntau optic cable.Cov tshuaj fiber ntau yuav maj mam deteriorate nyob rau lub sij hawm, feem ntau yog thawj agglomerate rau hauv me me hais, thiab ces maj mam evaporate, sib txawv, thiab qhuav.
3. Kev xaiv cov khoom siv thiab cov txheej txheem kos duab ntawm optical cable txheej
Cov laj thawj tseem ceeb rau kev poob ntawm kev ua haujlwm OPGW cable suav nrog hydrogen poob, cable tawg, thiab kev ntxhov siab cable.Tom qab kev sim ua tau zoo, nws pom tau tias tom qab xyoo ntawm kev siv OPGW cable, nws cov yam ntxwv ntawm kev sib txuas, thiab cov yam ntxwv kho qhov muag tsis tau hloov pauv.Tom qab kuaj xyuas, Lub tshuab ntsuas hluav taws xob pom tau tias cov kab hluav taws xob kho qhov muag tsis muaj qhov tshwm sim txawv txav xws li micro-cracks.Txawm li cas los xij, nws tau raug pom tias txheej txheej ntawm OPGW cable tsis zoo, thiab qhov attenuation ntawm optical cable nrog siab modulus, nruj txheej thiab loj tev quab yuam yuav pom tseeb dua.
Hauv kev siv tiag tiag, cov kab hluav taws xob kho qhov muag yuav muaj qee qhov ua tsis tiav vim qee qhov laj thawj sab nraud lossis teeb meem zoo.Yog li ntawd, yog tias koj xav siv nws mus ntev, nws yuav tsum yog technically tsim nyog.Zoo yog lo lus kawg.
