Raws li cov chaw tsim khoom siv fiber ntau optic, nws yog qhov tseem ceeb rau peb kom meej meej piav qhia txog cov txheej txheem kev teeb tsa tseem ceeb uas txuas rau qhov sib txawv ntawm "Kev teeb tsa OPGW Cable" thiab "ntev- lub sijhawm ua haujlwm txhim khu kev qha" rau OPGW fiber ntau optic: OPGW cov khoom siv txuas ntxiv tsis yog ib qho teeb meem ntawm "txuas" kho vajtse. Nws ncaj qha txiav txim siab seb OPGW fibers yuav raug pinched lossis hnav, txawm tias kev vibration qaug zog raug txwv, txawm hais tias hauv av thiab jumpers tseem nyob ruaj khov nyob rau lub sijhawm, thiab seb puas splice kaw thiab txuas txuas txuas ntxiv txhim khu kev qha, txhim khu kev qha kev txhim khu kev qha. nteg fiber ntau optic cable yuav tsum tau nyob rau ib ntus Cov kev taw qhia threading ntawm tag nrho cov bolts thiab pins ntawm lub kho qhov muag cable ace hardware yuav tsum ua raws li cov bolts ntawm lwm yam grounding hardware.
Ua ntej-Kev tsim kho ua ntej
Ua ntej OPGW fiber accessory installation, ua ntej -kev tsim kho yuav tsum tau lees paub. Cov no txiav txim siab seb qhov project puas tuaj yeem ua tiav tau raug, seb qhov kev lees paub tuaj yeem ua tau zoo ib yam, thiab ua kom muaj kev tshem tawm cov kev pheej hmoo txaus ntshai ua ntej.
Yuav kom txhim kho qhov zoo thiab sib xws, cov xwm txheej hauv qab no yuav tsum tau ua ua ntej kev tsim kho:
Kab tensioning, sag verification, thiab clamp txoj hauj lwm pom zoo ua tiav
Kev tiv thaiv ib ntus thiab kev ntsuas kev nyab xeeb ua haujlwm tau lees paub nyob rau hauv qhov chaw
Ua kom tiav cov fittings, armor rods, vibration dampers, splice kaw, thiab lwm yam cuab yeej accessory nrog traceable batch tooj
Cov cuab yeej torque, ntsuas cov cuab yeej, thiab cov cuab yeej tshwj xeeb stringing thiab nqa khoom muaj
Kev ua haujlwm ib puag ncig ua tau raws li qhov xav tau ntawm kev ua haujlwm tam sim no
Dab tsi yog OPGW Accessory Fitting Installation suav nrog?
Nkag siab txog OPGW cov khoom siv haum rau kev teeb tsa yog qhov tseem ceeb. Lub sij hawm ntev - lub sij hawm txhim khu kev qha ntawm OPGW nyob ntawm tsis yog tsuas yog nyob rau ntawm optical fiber cable nws tus kheej xwb, tab sis tseem ceeb tshaj ntawm "yuav ua li cas quab yuam kis tau tus mob, yuav ua li cas kev co tswj, yuav ua li cas hluav taws xob txuas ntxiv yog khaws cia, thiab yuav ua li cas splices raug kaw", tag nrho cov uas yog tiav los ntawm accessory haum installation. Txawm hais tias lub cable zoo heev, kev teeb tsa tsis raug yuav luag tag nrho cov kab ke mus rau qib qis kev ntseeg siab. OPGW accessory haum installation feem ntau suav nrog 7 modules hauv qab no:
• opgw ncua kev kawm ntawv ClampKev teeb tsa:Ua tiav cov load- bearing thiab swinging txav, tiv thaiv OPGW fiber optic cable los ntawm clamping puas thiab puas. Lub hom phiaj tseem ceeb yog nyob rau ntawm qhov chaw ntawm cov cuab yeej cuab tam los yog cushions, thiab seb lub clamp quab yuam yog qhov tseeb, kom ntseeg tau tias lub cable tsis tsim kev sib tsoo hauv zos los yog cov ntsiab lus sib txhuam thaum lub sij hawm ntev - cua sway.
•opgw tKev ClampKev teeb tsa:Dais nro thiab hloov rog smoothly. Seb qhov chaw yog qhov tseeb, thiab seb puas muaj armor rod wrapping kev taw qhia thiab uniformity raws li qhov yuav tsum tau, tiv thaiv cable slippage, xoob strands, los yog kev nyuaj siab concentration.
• Kev vibration Damper(Anti-Vibration Device) Installation:Suppresses qaug zog tshwm sim los ntawm aeolian vibration thiab galloping. Tus qauv, qhov ntau, thiab qhov chaw teeb tsa yuav tsum ua raws li cov qauv tsim thiab cov lus qhia tshwj xeeb, kom ntseeg tau tias ruaj khov thiab tiv thaiv - kev ntsuas xoob.
• opgw av xaim thiab jumper cableKev teeb tsa:Ua tiav hluav taws xob txuas ntxiv thiab muaj kev nyab xeeb tawm ntawm xob laim thiab induced tam sim no. Kev saib xyuas yuav tsum tau them rau seb cov ntsiab lus sib txuas ua tau zoo li cas, seb puas muaj kev tiv thaiv kev tiv thaiv - corrosion thiab waterproofing kev kho mob, thiab routing txoj kev yuav tsum abrasion -resistant thiab cua- sway kam rau ua.
• Down -kev teeb tsa kev teeb tsa:Yuav tsum ua raws li tus qauv hauv qab- coj txoj kev, tswj cov cua sway, tiv thaiv kev puas tsuaj thiab kev ntxhov siab. Kev kho cov ntsiab lus yuav tsum tau npaj kom tsim nyog, khoov lub vojvoog yuav tsum tau ua raws li qhov yuav tsum tau ua, thiab cuam tshuam nrog cov khoom siv ntauwd lossis cov ntsia hlau raug tshem tawm yuav tsum zam.
