OPGW kho qhov muag cabletseem hu ua optical fiber composite overhead ground wire.OPGW kho qhov muag cable OPGW kho qhov muag cable tso cov fiber ntau kho qhov muag hauv av xaim ntawm cov nyiaj siv ua haujlwm siab-voltage kis tau tus mob los tsim cov kev sib txuas lus fiber ntau ntawm cov kab sib kis.Cov qauv no muaj ob txoj haujlwm ntawm av xaim thiab kev sib txuas lus, thiab feem ntau hu ua OPGW optical cable.Kev tsim qauv ntawm OPGW yuav tsum xav txog kev sib koom tes nrog kev ntxhov siab ntawm cov xov hlau, sag thiab rwb thaiv tsev qhov sib txawv, thiab nws cov load yuav tsum tsis pub tshaj qhov tso cai ntawm cov yees thiab cov hauv paus.Yog li ntawd, tus yam ntxwv nkhaus yuav tsum tau xam raws li lub ntsiab technical tsis tau xaiv OPGW, thiab layout, txheej txheem thiab installation drawings ntawm lub hlws ris lub thawv, ntau yam kho vajtse thiab accessories yuav tsum tau tsim nyob rau hauv ua ke nrog nrog lub tiag tiag engineering.Kev nyeem ntawv txuas ntxiv: Yuav ua li cas OPGW cable manufacturers kom ntseeg tau qhov zoo ntawm optical cables
OPGW optical cable installation qauv tsim kev txiav txim siab
1. Kev kho qhov pib elongation
Rau kev kho mob ntawm qhov pib elongation ntawm OPGW, txoj kev txias tuaj yeem siv tau, uas yog, qhov sib piv ntawm aluminium-steel ntawm OPGW raug tshuaj xyuas, thiab qhov pib elongation yog kho nrog rau kev siv cov nqi txias ntawm cov hlau zoo sib xws lossis hauv av. hlau.
2. Tsim los tiv thaiv kev vibration ntsuas
Ntawm cov fittings siv los ntawm OPGW, qhov nro clamp yog ntawm pre-twisted hlau hom, thiab ncua kev kawm ntawv hlau clamp yog nruab nrog pre-twisted hlau thiab roj hmab gasket.Ob hom fittings no muaj qee yam kev tiv thaiv kev vibration.Txhawm rau ntxiv dag zog rau lub peev xwm tiv thaiv kev vibration, nws muaj peev xwm xav txog kev txhim kho lub rauj tiv thaiv kev vibration, uas feem ntau xam raws li qhov ntev:
Thaum qhov ncua sij hawm tsawg dua los yog sib npaug rau 300M, nruab ib qho kev tiv thaiv kev vibration rauj;
Thaum qhov ncua sij hawm yog> 300M, nruab ob lub thaiv kev vibration rauj.
3. Cov teeb meem uas yuav tsum tau them rau hauv kev tsim kho thiab erection ntawm OPGW
Kev tsim kho thiab erection ntawm OPGW yog txawv ntawm cov hlau zoo tib yam.Kev saib xyuas yuav tsum tau saib xyuas kom tsis txhob muaj kev puas tsuaj mus tas li kom tsis txhob cuam tshuam kev ua haujlwm ntawm cov khoom siv kho qhov muag yav tom ntej, thiab yuav tsum tsom mus rau: OPGW torsion, micro-bending, lub zog radial hauv zos sab nraum cov clip thiab cov pa phem rau cov khoom siv fiber ntau.Yog li ntawd, nyob rau theem kev tsim kho, cov kev ntsuas zoo hauv qab no yuav tsum tau coj los daws nws:
(1) Tiv thaiv OPGW los ntawm kev sib tw
Txhim kho qhov hnyav thiab tiv thaiv kev sib tw ntawm lub rooj tsavxwm thiab zawm clamp;
Txais yuav tshwj xeeb ob-groove pulley;
Nruas kab tshuab nrog ob chav winch;
(2) Tiv thaiv thiab txo qhov microbending thiab kev ntxhov siab ntawm OPGW
Tsis pub lub kaum ntse ntse (tsawg kawg bending vojvoog yog 500mm);txoj kab uas hla ntawm OPGW cable reel yuav tsum tsis pub tsawg tshaj 1500mm;
Txoj kab uas hla ntawm lub pulley yuav tsum yog ntau tshaj 25 npaug ntawm txoj kab uas hla ntawm OPGW, feem ntau tsis pub tsawg tshaj 500mm;sab hauv ntawm lub pulley yuav tsum muaj nylon lossis roj hmab hauv ob sab phlu los tiv thaiv khawb ntawm qhov chaw ntawm OPGW;
Tsim nyog rub hlau thiab them nyiaj fittings;
Qhia kom meej qhov siab tshaj plaws coil ntev ntawm OPGW yuav tsum yog 6000M los tiv thaiv tus naj npawb ntawm lub sij hawm lub pulley yog overrun;
Txoj kab sib hloov lub kaum sab xis ntawm kev them nyiaj tas mus li yog txwv rau ≤30 °.Nyob rau hauv qhov nro ntawm qhov them nyiaj, OPGW kev taw qhia tom qab lub ces kaum yuav tsum nyob rau hauv cov duab ntawm "C";
(3) Tswj kev them nyiaj tension:
Txais hydraulic nro them-tawm thiab tsheb laij teb nrog nro tso tawm ntaus ntawv;
Txwv kev them nyiaj ceev ≤ 0.5 m / s;
(4) Tiv thaiv kom txhob muaj kuab paug fiber ntau
Nyob rau hauv kev tsim kho thiab erection ntawm OPGW, yuav tsum tau them nyiaj mloog mus rau encapsulating qhov kawg;
Thaum kawg, peb yuav tsum ceeb toom rau txhua tus neeg tias ua ntej OPGW tuaj txog ntawm qhov chaw, ua ntej erection, tom qab ua tiav ntawm erection thiab kev sib txuas ntawm fiber ntau thiab ua tiav tag nrho cov kab kev tsim kho, OPGW fiber ntau attenuation lees txais yuav tsum tau nqa tawm. ntawm qhov chaw hauv lub sijhawm.
