Pab neeg kuaj kev lees paub ntawm lub Hoobkas yuav tsum xa daim ntawv lees paub, thiab cov khoom lag luam uas tsis lees txais yuav tsis tawm hauv lub hoobkas. Cov ntsiab lus, txoj hauv kev, thiab kev txiav txim siab rau lub Hoobkas lees txais ntawm ntau hom optical cables yuav tsum tau ua raws li cov qauv hauv lub tebchaws thiab cov qauv kev lag luam.Peb yuav tsom mus rau cov qauv kev lees paub rau cov khoom siv kho tshuab (xws li tensile lub zog, kev ntxhov siab{10}}cov yam ntxwv ntawm kev ua haujlwm, thiab kev ua haujlwm ntawm lub rubey) thiab ib puag ncig cov khoom (xws li dripping thiab dej nkag mus rau hauv av fiber ntau)(OPGW)kab.

OPGW Tensile thiab Stress -Kev Ntsuas Kev Ntsuas

Xeem Lub Hom Phiaj

Lub tensile thiab stress-strain test yog siv los txiav txim cov yam ntxwv kho qhov muag (hloov ntawm qhov kho qhov muag attenuation rate) thiab ntau yam khoom siv, nrog rau kev txwv kev ntxhov siab, ntawm chav kho qhov muag hauv qab tensile load. Qhov kev ntsuam xyuas no yog qhov tseem ceeb tshwj xeeb rau kev ntsuas qhov siab tshaj plaws ntawm fiber ntau optic cable ntev thiab deb npaum li cas ntawm fiber ntau optic cable tuaj yeem khiav hauv kev siv tau yam tsis muaj kev txwv tsis pub dhau kev nyab xeeb. Kev ntsuas tensile thiab kev ntxhov siab-kev kuaj mob yuav tsum ua raws liGB/T 1179-2017thiabDL/T 832-2016.

Test Apparatus

Lub tensile thiab kev ntxhov siab-cov cuab yeej kuaj kab mob muaj cov kab rov tav tensile kuaj tshuab (raws li pom nyob rau hauv daim duab 1-1) thiab ib tug optical fiber ntau tester muaj li ntawm ib tug optical fiber dispersion tester thiab ib tug optical time-domain reflectometer (OTDR) (raws li qhia nyob rau hauv daim duab 1-2). Thaum ua kev ntsuas kho qhov muag fiber ntau, lub teeb pom kev zoo thiab lub zog ntsuas hluav taws xob yuav tsum tau teeb tsa ntawm ob qho kawg ntawm qhov ntsuas qhov muag fiber ntau. Ob qhov kawg ntawm cov qauv kuaj yuav tsum tau kho nrog engineering txuam fittings ua ntej siv lub zog los xyuas kom meej tias lub kho qhov muag chav tsev tsis hloov pauv mus rau qhov kho qhov muag cable.

Txoj Kev Xeem

Thaum lub sijhawm kuaj, qhov deb ntawm fiber ntau optic rau cov qauv yuav tsum tsis pub tsawg tshaj 100m kom raug simulate tiag tiag -world fiber optic cable nrug daim ntawv scenarios. Nruab cov qauv kho qhov muag ntawm lub tshuab kuaj tensile, fusion splice cov fibers optical rau hauv ib lub voj, thiab ntsuas qhov poob hauv 1550nm wavelength band thaum sib txawv loads siv rau cov fiber ntau optical. Lub optical fiber yuav tsum tau so kom txaus rau thawj zaug load ua ntej thiab tom qab siv lub load. Thaum lub sij hawm ntsuas, saib xyuas cov cable load, optical fiber poob, optical fiber strain, thiab cable strain ntawm ib tug sampling zaus ntawm 1Hz. Cov kauj ruam ua haujlwm yog raws li nram no:

1. Siv thawj zaug load rau 2% ntawm qhov ntsuas tensile lub zog (RTS) kom ncaj cov kab hluav taws xob kho qhov muag, tom qab ntawd tshem tawm cov khoom thauj thiab nruab qhov ntsuas qhov ntsuas tsis muaj qhov nro;
2. Nce lub load rau 30% RTS, tuav rau 30min, nyeem ntawv ntawm 5min, 10min, 15min, thiab 30min, ces unload mus rau thawj load;
3. Rov ua dua lub load rau 50% RTS, tuav rau 1h, nyeem ntawv ntawm 5min, 10min, 15min, 30min, 45min, thiab 60min, ces unload mus rau qhov pib load;
4. Rov ua dua lub load rau 70% RTS, tuav rau 1h, nyeem ntawv ntawm 5min, 10min, 15min, 30min, 45min, thiab 60min, ces unload mus rau qhov pib load;
5. Rov ua dua lub load rau 85% RTS, tuav rau 1h, nyeem ntawv ntawm 5min, 10min, 15min, 30min, 45min, thiab 60min, ces unload mus rau qhov pib load;
6. Rov ua dua lub load kom txog rau thaum lub optical cable tawg, nyeem cov tensile quab yuam thiab elongation ntawm lub sij hawm dhau los ib ntus thaum sib npaug nce mus txog 85% RTS. Cov kauj ruam kawg no yuav pab txiav txim siab qhov siab tshaj plaws rub lub zog ntawm fiber ntau optic cable thiab cov tswv yim txwv rau rub cov fiber ntau optic cable thaum lub sijhawm teeb tsa.

• Thaum lub sijhawm kuaj, tus nqi thauj khoom tsis zoo yuav tsum tau khaws cia, zoo dua mus txog 30% RTS hauv 1-2min.
• Qhov kev ntsuas ntsuas kev hloov pauv ntawm cov fiber ntau optical poob, kho qhov muag fiber ntau, thiab cov ntaub ntawv txwv tsis pub dhau, raws li pom hauv daim duab 1-3.

Daim duab 1-3: Optical Cable Stress-Strain Test Curve Diagram

Nyob rau hauv daim duab 1-3, nkhaus 1 sawv cev rau cable strain, nkhaus 2 sawv cev rau optical fiber strain, nkhaus 3 sawv cev rau optical fiber poob yam ntxwv, thiab point A yog qhov tseem ceeb point uas lub optical fiber pib strain tom qab lub cable raug ib tug tej yam kev ntxhov siab; Nyob rau ntawm no, lub cable strain yog sib npaug rau qhov ntev ntawm cov fiber ntau optical.

Kev Xeem Xeem

1. Thaum cov kev ntxhov siab ntawm cable nce mus txog qhov nruab nrab txhua xyoo kev khiav hauj lwm nro (txhua hnub kev ntxhov siab, EDS) ntawm 18% -25% RTS, cov fiber ntau optical yuav tsum tsis muaj strain thiab tsis muaj kev poob ntxiv.
2. Thaum ncav cuag qhov siab tshaj plaws tso cai nruj (MAT) ntawm 40% RTS, qhov kho qhov muag fiber ntau yuav tsum qis dua 0.05% (txheej- hom stranded) lossis 0.1% (central tube hom), tsis muaj kev poob ntxiv; nyob rau hauv MAT load, yog hais tias tus nqi fiber ntau optical poob tau ntsib ib tug mus tas li los yog ib ntus nce siab tshaj tus nqi teev, qhov kev ntsuam xyuas yog xam tsis tau.
3. Thaum mus txog qhov kawg ntawm kev khiav hauj lwm lub zog (UOS) ntawm 60% RTS, qhov kho qhov muag fiber ntau yuav tsum qis dua 0.35% (txheej-stranded type) lossis 0.5% (central tube type), thiab cov fiber ntau optical poob yuav tsum rov zoo li qub tom qab qhov nro tawm. Yog tias qhov kawg ntawm qhov kev ntxhov siab ntawm qhov kho qhov muag fiber ntau tsawg dua UOS, qhov kev ntsuam xyuas tau pom tias ua tsis tiav. Cov kev pib no cuam tshuam ze rau qhov ntev ntev rau fiber ntau optic cable nyob rau hauv kev ua haujlwm loads.
4. Yog tias ib qho ntawm OPGW cable [AS (aluminium{0}}clad steel) cov xov hlau, AA (aluminium alloy) xov hlau, thiab kho qhov muag fiber ntau] tawg ua ntej ncav cuag 95% RTS kev ntxhov siab, qhov kev ntsuam xyuas raug suav tias ua tsis tiav.

• Cov txheeb ze slippage ntawm lub cable, optical fiber, thiab kho qhov muag chav tsev thaum lub sij hawm qhov kev xeem yog suav hais tias yog ib tug ua tsis tau tejyam.
