Amandla aqhelekileyo intambo ye-fiber optic yomoya bandakanya Intambo ye-ADSS kunye ne-OPGW. Namhlanje siza kuthetha ngomahluko phakathi kwazo: ADSS VS OPGW.

I-OPGW imele i-Optical Ground Wire, esetyenziswa kwimigca yokudlulisela umbane. Yintambo esebenza imisebenzi emibini, njengokuphatha i-fiber optics yonxibelelwano kunye nokusebenza njengentambo yomhlaba. Oko kuyavakala kuba imigca yombane ifuna ukuxhonywa ukuze ikhuseleke kumbane nezinye izinto ezinjalo. Ngoko ke i-OPGW mhlawumbi idibanisa umsebenzi wokuxhoma kunye nokukwazi ukuhambisa idatha.

I-ADSS sisifinyezo esinye. I-ADSS imele i-All-Dielectric Self-Supporting. I-All-dielectric ithetha ukuba ayinazo naziphi na izinto zesinyithi, ngoko ke ayisebenzisi mbane. Ukuzixhasa kuthetha ukuba ayifuni izakhiwo zenkxaso zangaphandle; inokuthwala ubunzima bayo. Ngoko ke iintambo ze-ADSS kusenokwenzeka ukuba zisetyenziselwa unxibelelwano, kodwa zifakwe ngokwahlukileyo kwiintambo zombane. Mhlawumbi zisetyenziswa kwiindawo apho ungenakuzincamathisela kwiintambo zombane, njengasezindleleni okanye kwiipali ezahlukeneyo.

Ngoku, ukuze sihlukanise umahluko. Masiqale ngesakhiwo. I-OPGW ineefayibha ezibonakalayo ngaphakathi kwikhava yokukhusela, ejikelezwe zizinto eziqhubayo ezifana ne-aluminium okanye intsimbi. Oku kuyivumela ukuba isebenze njengocingo lomhlaba. I-ADSS, ekubeni i-all-dielectric, ingaba neefayibha kwisixhobo se-dielectric, mhlawumbi kunye neentambo ze-aramid zokuqina, kwaye azinazo iindawo zesinyithi. Ngoko ke ngokwesakhiwo, i-OPGW inesinyithi, i-ADSS ayinaso.

Ufakelo:
I-OPGW ifakwe phezulu kwiitoweri zothumelo, ithatha indawo yentambo yesiqhelo engashukumiyo (intambo yomhlaba). Ekubeni iyinxalenye yesiseko sombane, idityaniswe kwiindawo ezine-voltage ephezulu. Kwelinye icala, i-ADSS ifakwe yodwa. Isenokuba kwiipali zefowuni, ecaleni kwezakhiwo ezikhoyo, kodwa ingabi kwimigca yombane ngokwayo. Akufuneki ibe yinxalenye yenkqubo yombane, ngoko ke kukhuselekile ukuyiphatha kwiindawo ezingena-voltage ephezulu.

Izicelo:
I-OPGW isetyenziswa kwimigca yothumelo oluphezulu apho kufuneka khona zombini iziseko zomhlaba kunye nonxibelelwano. Yinxalenye yeziseko zophuhliso zegridi yamandla. I-ADSS isetyenziswa kwimigca yokusasaza, mhlawumbi kwiimeko zevolthi ephantsi, okanye apho ungakwazi ukuyifaka kwimigca yamandla. Yeyothungelwano lonxibelelwano oluzimeleyo, mhlawumbi kwiindawo zasezidolophini okanye ecaleni kweendlela apho kusetyenziswa khona iipali ezahlukeneyo.

Iimpawu zombane:
I-OPGW iyasebenza kwaye iyinxalenye yenkqubo yombane, ngoko ke kufuneka ikwazi ukumelana nee-voltages eziphezulu kunye nemisinga, kuquka nemisinga yempazamo. I-ADSS ayisebenzi, ngoko ke ayinakuphazanyiswa ngumbane kwaye ayibeki mngcipheko wokuqhuba umbane. Oko kuyenza ikhuseleke kwiindawo ezithile.

Amandla oomatshini:
Zombini kufuneka zomelele. I-OPGW ineengqimba zesinyithi ezinika amandla nokhuseleko. I-ADSS ixhomekeke kwizixhobo ze-dielectric kwaye mhlawumbi neKevlar ukuze ikwazi ukutyhafa. Ekubeni i-ADSS izixhasa ngokwayo, kufuneka yenzelwe ukusingatha ubunzima bayo ngaphandle kokugoba, nokuba kudlula ixesha elide. I-OPGW, njengenxalenye yomgca wombane, yenzelwe ukumelana noxinzelelo lokusingqongileyo olufanayo nolweziqhubi zombane, njengomoya, umkhenkce, kunye notshintsho lobushushu.

Izinto ezichaphazela okusingqongileyo:
I-OPGW ifakwe kwiindawo ezirhabaxa ezifana neentambo zombane, ngoko ke yakhelwe ukuba yomelele ngokuchasene nombane, ii-voltage eziphezulu, kunye noxinzelelo loomatshini. I-ADSS ingasetyenziswa kwiindawo ezingezizo ezomeleleyo, kodwa kusafuneka ikwazi ukumelana nemozulu. Ekubeni i-dielectric yonke, akufuneki ikhathazeke ngokugqwala kwe-galvanic okanye umbane oqhubayo, kodwa kufuneka imelane nemitha ye-UV kunye nomonakalo womzimba.

Iindleko kunye nokugcinwa:
I-OPGW isenokuba neendleko ezingcono xa kusakhiwa imigca emitsha yombane okanye kuphuculwe esele ikho kuba isebenzela iinjongo ezimbini. Nangona kunjalo, ukufakelwa kwayo kungadinga ubuchule bemigca yombane kunye nexesha lokungasebenzi. I-ADSS inokuba nexabiso eliphantsi kwiimeko apho kunganyanzelekanga ukuba utshintshe iziseko zombane ezikhoyo, yongeza nje iintambo ezintsha kwiipali ezahlukeneyo. Ukulungiswa kwe-OPGW kuya kubandakanya ukujongana negridi yombane, enokuba nzima, ngelixa i-ADSS inokuba lula kuba yahlukile.

Ezinye izinto ekufuneka uziqwalasele:
I-ADSS isenokuba neengxaki nge-arcing yebhendi eyomileyo ukuba ifakwe kufutshane nemigca ye-voltage ephezulu, kuba nangona ingaqhubi kakuhle, ii-voltage ezibangelwayo zinokubangela iingxaki. I-OPGW sele iyinxalenye yenkqubo yombane, ngoko ke yenzelwe ukujongana nezo ngxaki. Ubude be-span bunokwahluka. I-OPGW isetyenziswa kwii-span ezinde eziqhelekileyo kwii-towers ze-voltage ephezulu, ngelixa i-ADSS inokuba nezakhono ezahlukeneyo ze-span ngokusekelwe kuyilo lwayo.

Yima, kufuneka ndiqinisekise ukuba i-ADSS isetyenziswa ngokwenene kwimigca yokusasaza. Ndicinga ukuba imigca yokusasaza inamandla ombane aphantsi, njengaleyo izisa umbane emakhaya, ngoko ke mhlawumbi i-ADSS isetyenziswa apho kuba okusingqongileyo akudingi kakhulu. I-OPGW ngokuqinisekileyo yeyokuhambisa umbane ophezulu.

Kwakhona, ukwahlulwa kwe-voltage: I-ADSS ayisebenzisi umbane, ngoko ke inokufakelwa kufutshane neentambo zombane ngaphandle komngcipheko, kodwa i-OPGW yinxalenye yenkqubo yokumisa umhlaba yentambo yombane. Ngoko ke i-ADSS ingcono ekuthinteleni ukuphazamiseka kwe-electromagnetic.

Ngokuphathelele ixesha lokufakelwa, i-OPGW ingafuna ukuba umgca wombane ucinywe amandla okanye usebenze ngamaqela akhethekileyo, ngelixa i-ADSS ingafakwa ngamaqela e-telecom ngaphandle kokuchukumisa iziseko zombane.

Ngoko ke xa zidityaniswa zonke, umahluko ophambili usekwakhekeni kwazo (isinyithi vs. esingesisinyithi), indawo yokufakelwa (edityaniswe neentambo zombane vs. ezahlulwe), iipropati zombane (eziqhuba umbane vs. ezingaqhubi umbane), kunye neendawo zokusetyenziswa (uthumelo oluphezulu vs. i-voltage ephantsi okanye iinethiwekhi zonxibelelwano ezahlukeneyo).

   •         I-ADSS:Ubude besithuba obuguquguqukayo; ithintela iingozi zombane kodwa ifuna ukubekwa ngononophelo kufutshane neendawo ezine-voltage ephezulu.

Isishwankathelo:I-OPGW idibanisa unxibelelwano kunye nokusekelwa ngaphakathi kweegridi ze-voltage ephezulu, ngelixa i-ADSS inika isisombululo esingasebenzisi mbane, esizimeleyo kwi-telecom, ngokuqhelekileyo kwiindawo ezingafunekiyo. Ukhetho luxhomekeke kwiimfuno zombane, imeko yokufakelwa, kunye neemfuno zeziseko zophuhliso.
