Intambo ye-elektroniki- Intambo yomhlaba edityanisiweyo ene-Optical Fibers (OPGW) Wasin Fujikura
intshayelelo
► I-OPGW okanye eyaziwa ngokuba yi-Optical Ground Wire luhlobo lwesakhiwo sekhebula esinomxube we-optical transmission kunye ne-overhead ground wire yokudlulisa amandla. Isetyenziswa kwimigca yokudlulisela amandla njengekhebula le-optical fiber kunye ne-overhead ground wire enokubonelela ngokhuseleko lombane kunye nokuqhuba i-short circuit current.
► I-OPGW iqulathe iyunithi ye-optical tube yentsimbi engagqwaliyo, ucingo lwentsimbi olugqunywe nge-aluminium, ucingo lwe-aluminium alloy. Inesakhiwo setyhubhu yentsimbi engagqwaliyo ephakathi kunye nesakhiwo sokuxhunywa kwemigca. Singayila isakhiwo ngokwemeko yendawo eyahlukileyo kunye neemfuno zabathengi.
Uphawu
► Iyunithi yefayibha ye-optical yentsimbi engenasici yetyhubhu ekhululekileyo ephakathi okanye isakhiwo sokunamathela semaleko
► Ucingo lwe-aluminium alloy kunye ne-aluminium clad steel wire armored
► Igqunywe ngegrisi ethintela ukubola phakathi kweengqimba
► I-OPGW inokuxhasa umthwalo onzima kunye nokufakwa kwexesha elide
► I-OPGW ingahlangabezana neemfuno zocingo lomhlaba lwe-mechanical kunye ne-electric ngokulungisa umlinganiselo wentsimbi kunye ne-aluminium.
► Kulula ukuvelisa iinkcukacha ezifanayo zocingo olukhoyo olunokuthatha indawo yocingo olukhoyo olukhoyo.
► I-OPGW inika iiNkampani zoMbane ithuba lokusebenzisa iinqaba zazo kwezinye iinjongo ngaphandle kokuhambisa umbane. Ngotyalo-mali oluncinci, zinokubonelela ngeeNxibelelwano eziNamandla aphezulu kakhulu kwicandelo leTelecom.
Iimpawu zesicelo
► Intambo ye-OPGW iyasebenza, okanye ifakwe phakathi kwee-pylon zombane ezine-voltage ephezulu, intsimbi, umthi, okanye iipali zekhonkrithi ezinezixhobo ezifanelekileyo kunye nezincamathiselo. Inxalenye eqhubayo yentambo, kule meko intsimbi isebenzela ukubopha iinqaba ezikufutshane nomhlaba, kwaye ikhusela ii-conductors ezine-voltage ephezulu ekubethweni ngumbane.
► I-OPGW inophawu lokuba akukho mpembelelo yokungeniswa kwe-voltage ephezulu kwidatha edluliselwa ngeeFibers. Kungoko ke olu phawu lweFiber lusetyenziswa njengenzuzo ukudlulisa idatha kwimigca yokudlulisela amandla aphezulu.
► Iifayibha ezibonakalayo ngaphakathi kwintambo zingasetyenziselwa ukudlulisa idatha ngesantya esiphezulu. Isixhobo sombane singasebenzisa intambo ye-fiber optics kwi-SCADA yaso, inkqubo yokukhusela nokulawula umgca wokudlulisa, i-VOIP, kunye nezinye iinjongo zonxibelelwano. Kwiimeko ezinjalo, zingonga imali yokufaka iintambo zentsimbi ezongezelelweyo ezisebenza njengeentambo zomhlaba okanye zesikhuseli kwimigca yazo. Zinokuqeshisa okanye zithengisele amaqela esithathu ukuze zisebenze njengonxibelelwano lwe-fiber optic olukhawulezayo phakathi kwezixeko, kunye nezinye iinethiwekhi.
