Intambo yokubona ye-OPGWImigqa idinga ukuthwala imithwalo ehlukahlukene ngaphambi nangemuva kokumiswa, futhi idinga ukubhekana nezimo zemvelo ezinzima ezifana nezinga lokushisa eliphezulu ehlobo, umbani, iqhwa neqhwa ebusika, futhi kudingeka ibhekane nemisinga ehlala ibangelwa kanye nemfushane- imisinga yesifunda ebangelwa imigqa yesigaba samandla.Indawo yokusebenza enzima lapho izinga lokushisa likhuphuka ngenxa yemiphumela yokushisa, ngakho-ke, kubaluleke kakhulu ukukhetha ikhebula le-optical le-OPGW elifanele. 
(1) Ukukhethwa kwezinto ezingavuthiwe neziyisizayo: khetha imikhiqizo edume umhlaba wonke njengefiber optical eyinhloko, i-fiber paste evimba amanzi, umucu wensimbi engagqwali, i-aluminium clad steel wire (AS), i-aluminium alloy wire (AA), njll., ukuze qinisekisa izinkomba Zekhwalithi ezihamba phambili.
(2) Izici zikamshini zekhebuli yokubona ye-OPGW: Intambo eboshiwe ngaphandle komnyombo wekhebula le-OPGW optical ikakhulukazi yakhiwe intambo ye-AA (i-aluminium alloy wire) kanye ne-AS wire (i-aluminium clad steel wire) ukuze kuqinisekiswe amandla aphezulu, ukusebenza kahle okuphezulu, kanye ne-anti. -ukugqwala ukusebenza.Okuhle kakhulu, isizukulwane esisha samashubhu ensimbi engagqwali ayinhlanganisela imikhiqizo ye-OPGW optical cable ihlukile phakathi kwemikhiqizo efanayo, futhi ihlangabezana nezidingo eziphuthumayo zezwe lami i-500KV, 220KV kanye namanye amazinga kagesi ahlukene wokwakhiwa kokuxhumana kwe-line optical fiber.Ngokulungisa isilinganiso se-aluminium/yensimbi nezicaciso zezintambo, kunezinhlaka zekhebula ezingaphezu kuka-100 OPGW abasebenzisi abangazikhetha.
Emikhiqizweni yekhebula le-optical ye-OPGW yamashubhu axegayo, ububanzi bangaphandle bekhebula le-optical buyafana kumapharamitha wezobuchwepheshe.Ngenxa yenani elihlukile lemigqa ye-AS kanye nemigqa ye-AA, izici zomshini nezikagesi zezintambo ezibonakalayo ze-OPGW nazo zihlukile.Ukuze ufanise ukucindezelwa okuxekethile kwe-OPGW nomhlabathi ngakolunye uhlangothi, kuyadingeka ukuthi izakhiwo zabo zemishini, okuhlanganisa amandla e-tensile (RTS), i-elastic modulus, i-linear expansion coefficient, isisindo, kanye nobubanzi bangaphandle, kufanele kusondele kakhulu. ngangokunokwenzeka.
(3) Ukucindezeleka okukhulu kokusebenza (MAT): Uma ikhebula le-OPGW optical lisetshenziswa njengentambo ephansi yolayini wokudlulisa amandla, ukukhethwa kokucindezeleka okukhulu kokusebenza kufana nocingo oluvamile lomhlabathi, olufanele ukulungiswa kokucindezeleka kwe-sag. ngezikhathi ezahlukene, futhi yenelisa inkomba ephakathi nendawo kanye nentambo yaphansi yephimbo Phakathi kwezidingo zebanga.Ngaphansi kwalesi sisekelo, ukungezwani kufanele kukhululeke ngangokunokwenzeka ukuze kuqinisekiswe ukuthi i-fiber optical ayicindezelwe ngaphansi komthwalo.
(4) Ukucindezeleka kokusebenza kwansuku zonke (EDS) okumaphakathi: Ukunqunywa kwalelivelu kuthinta ngokuqondile ukusebenza okuphephile kwesikhathi eside kwentambo yokubona.Ngemuva kokwamukela izinyathelo zokulwa nokudlidliza ngokuhambisana nencazelo yokuklama komugqa, isilinganiso sokucindezelwa kokusebenza kwansuku zonke komqhubi yi-15-25% RTS, futhi ngokuvamile kuyanconywa ukuthi kuthathwe Inani liyi-18%.
(5) Umthamo wamanje wesekethe emfishane (I2t): Umthamo wamanje wesiyingi esifushane wekhebula ye-OPGW uhlobene namanje (I) egeleza ngentambo ye-OPGW lapho kwenzeka iphutha lesigaba esisodwa somhlaba ohlelweni, isenzo sokuvikela. isikhathi (t), izinga lokushisa lokuqala kanye nezinga lokushisa eliphezulu elivumelekile.Leli nani lihlobene eduze nezindleko zesakhiwo se-OPGW, futhi inkomba ye-shunt yesayensi neyongayo kakhulu ngemva kokuvala i-fiber optical kanye nezintambo eziphansi ezingu-2 kufanele zicatshangelwe.
(6) Ukulawulwa kobude obudlulele be-fiber optical kukhebula le-OPGW optical: ngokuvamile i-OPGW eboshiwe ithola ubude besibili obudlulele be-fiber optical ngokusonta ubude obeqile be-optical fiber kushubhu lensimbi engagqwali nokusonta ikhebula ukuze qinisekisa ukuthi i-fiber optical ayithinteki ikhebula le-OPGW ngaphansi kokucindezeleka okukhulu kokusebenza.Amandla;inkomba engcono kakhulu yokulawula ubude obeqile bekhebuli yokubona ye-OPGW, kanye nokuthuthukisa idizayini ngokuhlolwa kokucindezeleka okuhlanganiswe nezimo zokusebenza.
