Kauj ruam-los ntawm- Cov kauj ruam qhia: Txhim kho Preformed Tension Clamps rau ADSS Cable Tsis Ua Rau Fibers
Rau cov kws tshaj lij kev sib txuas lus thiab EPC cov neeg cog lus, ua kom lub sijhawm ntev - kev ntseeg siab ntawm Txhua tus - Dielectric Tus Kheej - Txhawb (ADSS) cable network yog qhov tseem ceeb tshaj plaws. Thaum lub sij hawm deployment, lubADSS nro clamp installationyog ib qho ntawm cov theem tseem ceeb tshaj plaws. Lub preformed tuag kawg clamp muab lub zog tuav lub zog ntev ntev, tab sis kev tuav tsis raug tuaj yeem yooj yim crush optical fibers, ua rau lub teeb liab poob los yog attenuation.
Koj yuav ua li cas thiaj li ruaj ntseg ntawm txoj kab yam tsis muaj kev cuam tshuam cov kab hluav taws xob txoj kev ncaj ncees? Qhov noOptical cable hardware installation qhiarhuav tshem qhov kev npaj tseem ceeb, ib kauj ruam tseeb -los ntawm - txheej txheem wrapping, thiab ua yuam kev saum toj kawg nkaus kom tsis txhob ntawm -site.
Cov ntsiab lus ceev: Vim li cas Preformed Tension Clamps?
Ib txwm bolted clamps cia siab rau cov neeg kho tshuab siab, uas tuaj yeem yooj yim deform lub ADSS lub tsho sab nrauv thiab pinch cov ilv fiber cores hauv. Piv txwv li, apreformed tuag kawgsiv helical ob txhais ceg uas qhwv smoothly nyob ib ncig ntawm lub cable. Qhov kev tsim no faib cov radial gripping quab yuam sib npaug ntawm thaj chaw loj dua, tiv thaiv cov fibers optical thaum ua tau raws li qhov siab tshaj plaws tensile load.
Theem 1: Kev Npaj Tseem Ceeb & Kev Tiv Thaiv Cable
Ua ntej nce tus ncej lossis ntauwd, kev kuaj xyuas ua ntej- txhim kho yog qhov tseem ceeb los tiv thaiv kev sib tsoo thiab cov khoom tsis sib haum.
1. Ua raws li Cov Lus Qhia
Tsis txhob kwv yees qhov loj me. Tshawb xyuas koj daim ntawv teev cov ntaub ntawv kom paub tseeb tias lub puab txoj kab uas hla ntawm lub preformed nro clamp precisely phim lub sab kab (OD) ntawm koj ADSS cable. Ib lub clamp uas me dhau yuav tsoo lub cable, thaum ib qho uas loj dhau yuav ua rau slippage nyob rau hauv hnyav cua los yog dej khov loads.
2. Ntawm -Tsev Neeg Tshawb Fawb
Xyuas kom paub tseeb tias cov qauv rods (sab hauv thiab txheej txheej, yog tias muaj) yog huv si, du, thiab tsis muaj burrs lossis khoov.
Xyuas kom koj muaj cov khoom txuas txuas kom raug, xws li thimble clevises, txuas txuas ntxiv, lossis thauj tog rau nkoj shackles, yuav tsum tau txuas qhov kawg tuag mus rau tus ncej bracket.
3. Kev tiv thaiv fiber ntau
Pw cov ntaub thaiv npog yog tias cov cable yuav tsum tau tuav hauv av. Tsis txhob rub lub ADSS cable hla cov pob zeb ntse lossis asphalt, raws li qhov sib sib zog nqus khawb ntawm lub tsho polyethylene (PE / AT) txo nws lub zog dielectric thiab taug qab tsis kam.
Theem 2: Kauj Ruam -los ntawm- Kauj Ruam Preformed Tension Clamp Installation
Ua raws li cov txheej txheem txheej txheem txheej txheem no los lav qhov kev nyab xeeb haum yam tsis muaj kev ntxhov siab tsis zoo ntawm cov khoom siv kho qhov muag sab hauv.
Kauj Ruam 1: Nruab Qhov Txuas Txuas Cov Khoom Siv thiab Muab Lub Thawv Thauj Khoom
Ua ntej, ruaj ntseg muab lub thimble clevis (los yog sib npaug shackle) rau tus ncej lossis ntauwd bracket. Muab qhov khoov ntawm preformed tuag kawg tuav hla lub thimble. Xyuas kom lub cim crossover (feem ntau yog xim -coded) ntawm lub clamps zoo kawg nkaus nrog lub hom phiaj qhov chaw ntawm koj ADSS cable.
Kauj Ruam 2: qhwv thawj subset ntawm Rods
Tuav cov ceg preformed ua ke. Pib qhwv cov helical rods mus rau ADSS cable kom meej meej ntawm tus cim crossover.
Qhwvob mus rau peb pitches (tig)nyob ib ncig ntawm lub cable siv koj txhais tes.
Nco tseg:Tsis txhob siv cov pliers, wrenches, lossis cov cuab yeej hlau los quab yuam cov pas nrig rau ntawm lub cable, vim qhov no yuav rub lub tsho tiv thaiv sab nraud.
Kauj Ruam 3: qhwv cov pas nrig uas seem thiab ruaj ntseg cov lus qhia
Thaum thawj lub subset tau ua raws thiab ib nrab qhov txhab, coj cov ceg tsis sib haum xeeb ntawm ob txhais ceg thiab pib qhwv lawv nyob rau hauv tib txoj kev. Xyuas kom cov pitches intertwine smoothly tsis overlapping los yog tawm qhov khoob.
Progressively cua ob subsets ib txhij mus rau qhov kawg.
Thaum koj ncav cuag cov lus qhia ntawm cov pas nrig, snap qhov xaus rau hauv qhov chaw maj mam. Xyuas kom txhua tus pas nrig taub snaps tag nrho nyob ib ncig ntawm lub tsho cable kom tsis txhob xoob xaus los ntawm kev ntes ntawm lwm yam khoom siv lossis vibrating hauv cua.
Theem 3: 3 Qhov yuam kev tseem ceeb uas ua rau muaj fiber ntau puas (Thiab yuav ua li cas zam lawv)
Txawm tias cov neeg ua haujlwm paub dhau los ua yuam kev uas ua rau micro- khoov lossis fiber ntau tawg tam sim ntawd. Ua tib zoo saib rau peb qhov teeb meem kev teeb tsa no:
Qhov yuam kev 1: Twisting lossis Hla -Wrapping Helical Rods
Lub Hazard:Yog hais tias tus qauv rods hla ib leeg es tsis txhob nteg sab - los ntawm - sab nyob rau hauv parallel alignment, nws tsim ib tug asymmetric siab - siab point.
Qhov Kho:Ib txwm pom kev tshawb xyuas qhov kawg tuag. Cov rods yuav tsum zoo li ib tug nruam, uniform kauv lub tes tsho. Yog hais tias ib tug pas nrig hla lwm tus, unwrap tam sim ntawd thiab re-install.
Ua yuam kev 2: Ntau dhau lawm -Tensioning Thaum lub installation
Lub Hazard:Rub lub ADSS cable kom deb dhau nws Qhov Kev Tso Cai Tshaj Tawm (MAT) siv hnyav -lub luag haujlwm tuaj- nrog rau kev tshem tawm sag tuaj yeem ua rau cov hlab ntsha tsis zoo. Qhov no tsim micro-bending poob uas degrade teeb liab zoo nyob rau lub sij hawm.
Qhov Kho:Siv lub dynamometer los saib xyuas cov kab nro thaum stringing. Nyob twj ywm nruj me ntsis nyob rau hauv lub sag- nro parameters muab los ntawm cov chaw tsim khoom cable.
yuam kev 3: Rov qab siv Deformed Preformed Clamps
Lub Hazard:Yog tias ib tus neeg ua haujlwm qhwv lub clamp tsis raug, tshem nws, thiab sim rov siv nws tom qab cov duab helical tau warped los yog dhau - ncab, qhov kev tuav pov hwm poob qis heev. Qhov no feem ntau ua rau cable slippage nyob rau hauv siab ib puag ncig loads.
Qhov Kho:High -zoopreformed tuag xausfeem ntau tuaj yeem hloov khoib zaugthaum pib installation yog ua kom zoo zoo. Txawm li cas los xij, yog tias cov pas nrig pom muaj qhov deformation mus tas li, muab pov tseg lub tsev thiab siv lub clamp tshiab kom ntseeg tau tias kev ruaj ntseg network.
