Ikhebula Le-elekthronikhi- I-Composite Overhead Ground Wire With Optical Fibers (OPGW) Wasin Fujikura
isingeniso
► I-OPGW noma eyaziwa ngokuthi i-Optical Ground Wire iwuhlobo lwesakhiwo sekhebula elinenhlanganisela yokudluliswa kwe-optical kanye nentambo yaphansi engaphezulu ukuze kudluliswe amandla. Isetshenziswa kolayini bokudluliswa kwamandla kokubili njengekhebula le-fiber optical kanye nentambo yaphansi engaphezulu enganikeza ukuvikeleka kokushaywa kombani kanye nokubamba isekethe yesifunda esifushane.
► I-OPGW iqukethe iyunithi ye-stainless steel tube optical, i-aluminium cladding steel wire, i-aluminium alloy wire. Inesakhiwo seshubhu yensimbi engagqwali ephakathi nendawo kanye nesakhiwo se-layer stranding. Singakwazi ukuklama isakhiwo ngokuvumelana nesimo sendawo ehlukene kanye nezidingo zekhasimende.
Isici
► Iyunithi ye-fiber optical yensimbi engagqwali yeshubhu evulekile emaphakathi noma uhlaka lwe-stranding
► I-aluminium alloy wire kanye ne-aluminium clad steel wire eboshwe
► Igcotshwe ngamafutha avimbela ukubola phakathi kwezingqimba
► I-OPGW ingasekela umthwalo osindayo nokufakwa kwesikhathi eside
► I-OPGW ingahlangabezana nemfuneko yocingo lwaphansi lwemishini nogesi ngokulungisa ingxenye yensimbi ne-aluminium.
► Kulula ukukhiqiza imininingwane efanayo yocingo lwaphansi olukhona lungangena esikhundleni socingo lwaphansi olukhona.
► I-OPGW inikeza Izinkampani Zamandla ithuba lokusebenzisa imibhoshongo yazo ngezinye izinjongo kunokudluliswa kwamandla. Ngokutshalwa kwezimali okuncane bangahlinzeka Ngezixhumanisi Ezisezingeni Eliphezulu Kakhulu emkhakheni weTelecom.
Izici zohlelo lokusebenza
► Ikhebula le-OPGW liyasetshenziswa, noma lifakwe phakathi kweziqongo zamapayipi kagesi anamandla amakhulu, insimbi, ukhuni, noma izigxobo zikakhonkolo ezinezixhumi ezifanele nezinamathiselo. Ingxenye yekhebuli, kulokhu insimbi isebenza ukuhlanganisa imibhoshongo eseduze nomhlaba, futhi ivikela amakhondatha anamandla aphezulu ekushayweni kombani.
► I-OPGW inesici sokuthi awukho umthelela wokungeniswa kwamandla kagesi aphezulu kudatha edluliswa ngama-Fibers. Ngakho-ke lesi sici se-Fiber sisetshenziselwa ukudlulisa idatha ngemigqa yokudlulisa amandla aphezulu.
► Amafayibha okubona ngaphakathi kwekhebula angasetshenziswa ekudluliseni idatha ngesivinini esikhulu. Isisetshenziswa sikagesi singasebenzisa intambo ye-fiber optics ku-SCADA yayo, isistimu yokuvikela nokulawula yolayini wokudlulisa, i-VOIP, nezinye izinjongo zokuxhumana. Ezimweni ezinjalo, bangonga ezindlekweni zokufaka izintambo zensimbi ezengeziwe ezisebenza njengezintambo eziphansi noma eziyisivikelo emigqeni yazo. Bangaphinda baqashise noma bathengiselwe abantu besithathu ukuze basebenze njengoxhumano lwe-fiber optic olunesivinini esikhulu phakathi kwamadolobha, namanye amanethiwekhi.
