Intambo Yomhlaba Ehlanganisiwe Yekhebula Le-elekthronikhi Enezintambo Zokukhanya (i-OPGW) Wasin Fujikura
isingeniso
► I-OPGW noma eyaziwa ngokuthi i-Optical Ground Wire uhlobo lwesakhiwo sekhebula esinokuhlanganiswa kokudluliselwa kwe-optical kanye nentambo yomhlabathi ephezu kwekhanda yokudlulisela amandla. Isetshenziswa emigqeni yokudlulisela amandla njengekhebula le-optical fiber kanye nentambo yomhlabathi ephezu kwekhanda enganikeza ukuvikelwa kokushaya kombani kanye nokuqhuba ugesi we-short circuit.
► I-OPGW iqukethe iyunithi ye-optical yeshubhu yensimbi engagqwali, intambo yensimbi embozwe nge-aluminium, intambo ye-aluminium alloy. Inesakhiwo seshubhu yensimbi engagqwali ephakathi kanye nesakhiwo sokugoba ungqimba. Singaklama isakhiwo ngokuya ngesimo sendawo esihlukile kanye nezidingo zamakhasimende.
Isici
► Iyunithi ye-fiber optical yensimbi engagqwali yeshubhu elivulekile eliphakathi noma isakhiwo sokugoba ungqimba
► Ucingo lwe-aluminium alloy kanye nocingo lwensimbi olumbozwe nge-aluminium oluhlonyiswe nge-armored
► Kugcotshwe ngamafutha alwa nokugqwala phakathi kwezingqimba
► I-OPGW ingasekela umthwalo osindayo kanye nokufakwa kwesikhathi eside
► I-OPGW ingahlangabezana nezidingo zocingo lomhlabathi zomshini nogesi ngokulungisa isilinganiso sensimbi ne-aluminium.
► Kulula ukukhiqiza imininingwane efanayo yocingo olukhona olungasetshenziswa esikhundleni socingo olukhona olukhona.
► I-OPGW inikeza Izinkampani Zikagesi ithuba lokusebenzisa imibhoshongo yazo ngenye injongo ngaphandle kokudlulisela ugesi. Ngotshalomali oluncane zinganikeza izixhumanisi Ezinamandla Aphezulu kakhulu emkhakheni wezokuxhumana.
Izakhiwo zohlelo lokusebenza
► Ikhebula le-OPGW liyasetshenziswa, noma lifakwe phakathi kweziqongo zama-pylon kagesi ane-voltage ephezulu, insimbi, ukhuni, noma izinsika zekhonkrithi ezinezihlanganisi nezinamathiselo ezifanele. Ingxenye eqhubayo yekhebula, kulokhu insimbi isebenzela ukubopha imibhoshongo eseduze nomhlabathi, futhi ivikele abaqhubi be-voltage ephezulu ekushayweni kombani.
► Ama-OPGW anesici sokuthi akukho mphumela wokungeniswa kwe-voltage ephezulu kudatha edluliselwa ngama-Fiber. Ngakho-ke lesi sici se-Fiber sisetshenziswa kahle ukudlulisa idatha ngemigqa yokudlulisa amandla aphezulu.
► Imicu ye-optical ngaphakathi kwekhebula ingasetshenziswa ekudlulisweni kwedatha ngesivinini esikhulu. Isikhungo sikagesi singasebenzisa ikhebula le-fiber optics kwi-SCADA yaso, uhlelo lokuvikela nokulawula umugqa wokudlulisa, i-VOIP, nezinye izinjongo zokuxhumana. Ezimweni ezinjalo, bangonga ezindlekweni zokufaka izintambo zensimbi ezengeziwe ezisebenza njengezintambo zomhlabathi noma ezivikelayo emigqeni yabo. Bangaqasha noma bathengisele abantu besithathu ukuze basebenze njengoxhumano lokuxhumana lwe-fiber optic olusheshayo phakathi kwamadolobha, namanye amanethiwekhi.
