Lub zog sib koom ua ke cable fiber optic hauv av suav nrog ADSS cable thiab OPGW. Hnub no peb yuav tham txog qhov txawv ntawm lawv: ADSS VS OPGW.

OPGW yog lub npe luv ntawm Optical Ground Wire, uas yog siv rau hauv cov kab xa hluav taws xob. Nws yog ib txoj hlua uas ua haujlwm ob lub hom phiaj, zoo li nqa fiber optics rau kev sib txuas lus thiab ua haujlwm ua xov hlau av. Qhov ntawd ua rau muaj kev nkag siab vim tias cov kab hluav taws xob xav tau av los tiv thaiv xob laim thiab lwm yam. Yog li OPGW tej zaum yuav muab kev ua haujlwm av nrog rau kev xa cov ntaub ntawv.

ADSS yog lwm lub npe luv. ADSS sawv cev rau All-Dielectric Self-Supporting. All-dielectric txhais tau tias nws tsis muaj cov khoom siv hlau, yog li nws tsis yog-conductive. Self-supporting qhia tias nws tsis xav tau cov qauv txhawb nqa sab nraud; nws tuaj yeem tuav nws tus kheej qhov hnyav. Yog li ADSS cables yuav siv rau kev sib txuas lus thiab, tab sis lawv tau teeb tsa sib cais ntawm cov xov hluav taws xob. Tej zaum lawv tau siv rau hauv qhov chaw uas koj tsis tuaj yeem txuas lawv rau cov xov hluav taws xob, xws li ntawm txoj kev lossis cov ncej sib cais.

Tam sim no, los rhuav tshem qhov sib txawv. Cia peb pib nrog cov qauv. OPGW muaj cov fibers optical hauv lub plhaub tiv thaiv, uas nyob ib puag ncig los ntawm cov ntaub ntawv conductive xws li txhuas lossis hlau. Qhov no tso cai rau nws ua haujlwm ua cov xov hlau hauv av. ADSS, yog tag nrho-dielectric, yuav muaj cov fibers hauv cov khoom siv dielectric, tej zaum nrog cov xov aramid rau lub zog, thiab tsis muaj cov khoom hlau. Yog li structurally, OPGW muaj hlau, ADSS tsis muaj.

Kev Teeb Tsa:
OPGW raug teeb tsa rau saum cov pej thuam xa xov, hloov cov xov hlau zoo li qub (xov hlau hauv av). Vim nws yog ib feem ntawm cov kab hluav taws xob, nws tau koom ua ke rau hauv cov chaw muaj hluav taws xob siab. ADSS, ntawm qhov tod tes, raug teeb tsa cais. Nws yuav nyob rau ntawm cov ncej xov tooj, raws cov qauv uas twb muaj lawm, tab sis tsis yog ntawm cov kab hluav taws xob lawv tus kheej. Nws tsis tas yuav yog ib feem ntawm lub kaw lus hluav taws xob, yog li nws muaj kev nyab xeeb dua los tuav hauv cov chaw tsis muaj hluav taws xob siab.

Cov ntawv thov:
OPGW siv rau hauv cov kab xa hluav taws xob siab uas xav tau kev sib txuas lus thiab kev sib txuas lus. Nws yog ib feem ntawm lub zog fais fab. ADSS siv rau hauv cov kab faib khoom, tej zaum qhov xwm txheej qis dua, lossis qhov twg koj tsis tuaj yeem teeb tsa rau ntawm cov kab hluav taws xob. Nws yog rau cov tes hauj lwm sib txuas lus, tej zaum hauv nroog lossis raws txoj kev uas siv cov ncej sib cais.

Cov khoom siv hluav taws xob:
OPGW yog conductive thiab yog ib feem ntawm lub tshuab hluav taws xob, yog li nws yuav tsum tau tswj cov voltages siab thiab currents, suav nrog cov fault currents. ADSS tsis yog conductive, yog li nws tsis raug cuam tshuam los ntawm hluav taws xob thiab tsis muaj kev pheej hmoo ntawm kev conducting hluav taws xob. Qhov ntawd ua rau nws muaj kev nyab xeeb dua hauv qee qhov chaw.

Lub zog kho tshuab:
Ob leeg yuav tsum muaj zog. OPGW muaj cov txheej hlau uas muab lub zog thiab kev tiv thaiv. ADSS vam khom cov ntaub ntawv dielectric thiab tej zaum Kevlar rau lub zog tensile. Vim tias ADSS yog tus kheej txhawb nqa, nws yuav tsum tau tsim los tswj nws tus kheej qhov hnyav yam tsis muaj sagging, txawm tias dhau lub sijhawm ntev. OPGW, yog ib feem ntawm txoj kab hluav taws xob, yog tsim los tiv taus tib qho kev ntxhov siab ib puag ncig zoo li cov neeg xa hluav taws xob, xws li cua, dej khov, thiab kev hloov pauv kub.

Tej yam ib puag ncig:
OPGW raug teeb tsa rau hauv tib qho chaw ib puag ncig hnyav li cov xov hluav taws xob, yog li nws tau tsim los kom ruaj khov tiv thaiv xob laim, hluav taws xob siab, thiab kev ntxhov siab ntawm lub tshuab. ADSS yuav siv tau rau hauv qhov chaw tsis hnyav heev, tab sis tseem yuav tsum tiv taus huab cua. Vim tias nws yog dielectric tag nrho, nws tsis tas yuav txhawj txog kev xeb galvanic lossis kev coj xob laim, tab sis nws yuav tsum tiv taus hluav taws xob UV thiab kev puas tsuaj rau lub cev.

Tus nqi thiab kev saib xyuas:
OPGW tej zaum yuav pheej yig dua thaum tsim cov kab hluav taws xob tshiab lossis hloov kho cov uas twb muaj lawm vim nws ua haujlwm ob lub hom phiaj. Txawm li cas los xij, kev teeb tsa yuav xav tau kev txawj ntse ntawm cov kab hluav taws xob thiab lub sijhawm tsis ua haujlwm. ADSS yuav pheej yig dua hauv cov xwm txheej uas koj tsis tas yuav hloov kho cov khoom siv hluav taws xob uas twb muaj lawm, tsuas yog ntxiv cov xov hlau tshiab rau ntawm cov ncej sib cais. Kev saib xyuas rau OPGW yuav cuam tshuam nrog kev daws teeb meem nrog lub zog hluav taws xob, uas tuaj yeem nyuaj, thaum ADSS yuav yooj yim dua vim nws sib cais.

Lwm yam kev xav txog:
ADSS tej zaum yuav muaj teeb meem nrog cov kab qhuav arcing yog tias ntsia ze ntawm cov kab hluav taws xob siab, vim tias txawm tias nws tsis yog-conductive, induced voltages tuaj yeem ua rau muaj teeb meem. OPGW twb yog ib feem ntawm lub kaw lus hluav taws xob, yog li nws tau tsim los daws cov teeb meem ntawd. Qhov ntev ntawm Span kuj tuaj yeem txawv thiab. OPGW siv rau hauv qhov ntev ntawm cov pej thuam high-voltage, thaum ADSS tej zaum yuav muaj peev xwm sib txawv raws li nws tsim.

Tos, kuv yuav tsum xyuas seb ADSS puas siv rau ntawm cov kab faib khoom. Kuv xav tias cov kab faib khoom muaj qhov hluav taws xob qis dua, zoo li cov uas coj hluav taws xob mus rau tsev, yog li tej zaum ADSS siv nyob ntawd vim tias ib puag ncig tsis tas siv zog ntau. OPGW yeej yog rau kev xa hluav taws xob siab.

Tsis tas li ntawd, kev rho tawm hluav taws xob: ADSS tsis coj hluav taws xob, yog li nws tuaj yeem ntsia tau ze ntawm cov kab hluav taws xob yam tsis muaj kev pheej hmoo, tab sis OPGW yog ib feem ntawm lub kaw lus av ntawm cov kab hluav taws xob. Yog li ADSS zoo dua rau kev zam kev cuam tshuam hluav taws xob.

Hais txog lub sijhawm teeb tsa, OPGW yuav xav kom cov kab hluav taws xob raug tshem tawm hluav taws xob lossis ua haujlwm los ntawm cov neeg ua haujlwm tshwj xeeb, thaum ADSS tuaj yeem teeb tsa los ntawm cov neeg ua haujlwm hauv telecom yam tsis tau kov cov khoom siv hluav taws xob.

Yog li muab txhua yam ua ke, qhov sib txawv tseem ceeb yog nyob rau hauv lawv txoj kev tsim kho (hlau vs. tsis yog hlau), qhov chaw teeb tsa (kev koom ua ke nrog cov kab hluav taws xob vs. sib cais), cov khoom hluav taws xob (conductive vs. tsis yog conductive), thiab cov chaw siv (kev sib kis hluav taws xob siab vs. qis dua lossis cov tes hauj lwm sib txuas lus sib cais).
