Intambo ye-OPGW (Optical Ground Wire) luhlobo oluthile lwentambo olusetyenziswa kwimigca yokudlulisa amandla ephezu komhlaba. Iqulathe zombini iifayibha ze-optical zokudlulisa idatha kunye nomqhubi wesiqhelo wokudlulisa amandla ombane. Iifayibha ze-optical ezikwintambo ye-OPGW zihlala zigqunywe ngumaleko okhuselayo ukuze zikhuseleke kwiimeko ezingqongileyo ezifana nokufuma, ukuguquguquka kobushushu, kunye nomonakalo womzimba.

Intambo ye-OPGW inikezela ngeenzuzo ezininzi:

Ukusebenza kabini: Intambo ye-OPGW isebenza ngeenjongo ezimbini zokuthwala umbane kunye nokudlulisa idatha ngeefayibha ze-optical, ngaloo ndlela kunciphisa imfuneko yeziseko zophuhliso ezahlukeneyo zonxibelelwano.

Ukuthembeka: Ngokudibanisa iifayibha ze-optical kwinkqubo yokudlulisa umbane, intambo ye-OPGW ibonelela ngendlela ethembekileyo yonxibelelwano ngeenjongo zokubeka esweni nokulawula.

Ukhuseleko: Iintambo ze-OPGW zenzelwe ukumelana neemeko ezinzima zemigca yokudlulisa umbane ephezulu, ukuqinisekisa ukhuseleko kunye nokuthembeka kunxibelelwano kunye nokudlulisa umbane.

I-bandwidth ephezulu: Iifayibha ze-optical ezisetyenziswa kwiintambo ze-OPGW zibonelela ngezakhono eziphezulu ze-bandwidth, ezivumela ukuhanjiswa kwedatha eninzi kumgama omde ngaphandle kokulahleka okukhulu kwesiginali.

Ukhuseleko: Uyilo lwentambo ye-OPGW luquka iileya zokukhusela ukuzikhusela kwiingxaki zokusingqongileyo kunye noxinzelelo loomatshini, ukuqinisekisa ukuba zihlala ixesha elide kwaye zithembekile.

Ukufakwa kwekhebula le-OPGW

Lilonke, intambo ye-OPGW idlala indima ebalulekileyo kwiinethiwekhi zothutho lwamandla zanamhlanje ngokulungiselela unxibelelwano olusebenzayo kunye nokubeka esweni ngelixa kuqinisekiswa uthutho oluthembekileyo lwamandla ombane.

Ukufakelwa kwe-OPGW (Optical Ground Wire) kudla ngokubandakanya amanyathelo aliqela ukuqinisekisa ukuhlanganiswa okufanelekileyo kwimigca yokudlulisa amandla ephezu kwentloko. Nantsi inkcazo ngokubanzi yenkqubo yokufakela:

Ukulungiselela: Ngaphambi kokuba kuqalwe ukufakwa, ucwangciso olucokisekileyo kunye nokulungiselela kubalulekile. Oku kuquka ukuvavanya indlela yomgca wokuhambisa umbane, ukumisela ubude obufunekayo bentambo ye-OPGW, kunye nokuqinisekisa ukuba zonke izixhobo kunye nezinto ezifunekayo ziyafumaneka.

Ukucoca kunye nokuhlola: Indawo ejikeleze umgca wokuhambisa umbane isusiwe kuyo nayiphi na imiqobo okanye izityalo ezinokuphazamisana nenkqubo yokufakela. Umgca wokuhambisa umbane ngokwawo uyahlolwa ukuqinisekisa ukuba usemgangathweni ngokwesakhiwo kwaye unako ukuxhasa ubunzima obongezelelweyo bentambo ye-OPGW.

Ukufakelwa kwezixhobo: Izixhobo ezikhethekileyo, ezifana nee-suspension clamps, ii-vibration dampers, kunye nee-splice boxes, zifakelwe ecaleni komgca wokuhambisa umbane ukuxhasa nokukhusela intambo ye-OPGW. Ezi zixhobo zezixhobo zihlala zenzelwe ukumelana noxinzelelo loomatshini kunye neemeko zokusingqongileyo ezikhoyo kwiindawo zokuhambisa eziphezu komhlaba.

Ukudibanisa intambo ye-OPGW: Intambo ye-OPGW ibotshelelwe ngononophelo kubude bomgca wokuhambisa umbane kusetyenziswa izixhobo ezikhethekileyo ezifana nee-tensioners, oomatshini bokutsala, kunye nezixhobo zokujonga uxinzelelo. Intambo kufuneka ifakwe ngoxinzelelo olufanelekileyo ukuqinisekisa ukuthembeka nokusebenza kwayo.

Ukupheliswa kunye nokuQokelelwa: Nje ukuba intambo ye-OPGW ibekwe endaweni yayo, iyacinywa kuzo zonke iziphelo zomgca wokudlulisela kusetyenziswa ukuvalwa kwe-splice okanye iibhokisi zokuphelisa. Iifayibha ze-optical ezingaphakathi kwintambo nazo zinokufuna ukudityaniswa ukuze kudalwe iindlela zonxibelelwano eziqhubekayo kubude bomgca.

Uvavanyo kunye nokuQalisa: Emva kokuba ukufakelwa kugqityiwe, uvavanyo olucokisekileyo lwentambo ye-OPGW kunye nezixhobo ezinxulumene nayo luyenziwa ukuqinisekisa ukusebenza kwayo kunye nokusebenza kwayo. Oku kungabandakanya uvavanyo lokuqhuba umbane, ukulahleka kwesignali ye-optical, ukuthembeka koomatshini, kunye nokuthembeka konxibelelwano.

Amaxwebhu kunye noLondolozo: Amaxwebhu aneenkcukacha ngenkqubo yokufakela, kuquka imizobo eyakhiweyo kunye neziphumo zovavanyo, aqulunqwe ukuze kusetyenziswe wona kwixesha elizayo. Ukugcinwa rhoqo kunye nokuhlolwa kwentambo ye-OPGW kubalulekile ukuqinisekisa ukuthembeka nokusebenza kwayo okuqhubekayo.

Lilonke, ukufakwa kwentambo ye-OPGW kufuna ucwangciso olucokisekileyo, abasebenzi abanezakhono, kunye nezixhobo ezikhethekileyo ukuqinisekisa ukuhlanganiswa okufanelekileyo kwimigca yokuhambisa umbane ephezulu. Ukulandela iinkqubo ezimiselweyo kunye neendlela ezilungileyo kubalulekile ukwandisa ukuthembeka kunye nobude bexesha leziseko ezifakiweyo.
