Intambo yaphansi ye-OPGW, eyaziwa nangokuthi i-optical fibre composite overhead ground wire, intambo yaphansi engaphezulu equkethe i-optical fiber enezici eziningi ezifana nentambo yaphansi kanye nokuxhumana okubonakalayo.Isetshenziselwa ikakhulukazi izintambo zokuxhumana ezingu-110kV, 220kV, 500kV, 750kV kanye nezinhlelo ezintsha zokudlulisa amandla kagesi aphezulu.
Ikhebula le-optical le-OPGW elidumile lizuze impumelelo kwezobuchwepheshe, kodwa impilo yayo yesevisi nayo iyinkinga yawo wonke umuntu.Uma ufuna impilo ende yesevisi yekhebula le-optical, kufanele unake amaphuzu amathathu obuchwepheshe alandelayo:
1. Usayizi weshubhu oxegayo
Umthelela wosayizi weshubhu elixegayo esikhathini sokuphila sekhebula le-OPGW liphinde libonakale ekucindezelweni kokungeniswa.Uma ubukhulu buncane kakhulu, ngaphansi kwezici zokushintsha kwezinga lokushisa, ukucindezeleka komshini, kanye nokusebenzisana phakathi kokugcwalisa nekhebula le-optical, ukucindezeleka kukhebula le-optical ngeke kuncishiswe kahle, okuzosheshisa ukwehla empilweni ye-optical cable. Intambo yokubona ye-OPGW futhi ibangele ukuguga..
2.ukuhlelwa kokugcwalisa amafutha
I-fiber paste into enamafutha ye-OPGW optical cable.Kuyingxube esuselwe kuwoyela wamaminerali noma uwoyela wokuhlanganisa, onomphumela wokuvimba umhwamuko wamanzi nokubhafa kukhebuli yokubona.Umsebenzi we-fiber paste uhlolwa ngokuhlola isikhathi sokungeniswa kwe-oxidation samafutha.Ngemuva kokuthi amafutha enziwe nge-oxidized, inani layo le-asidi lizokhula, okungaholela ekwandeni kokuguquguquka kwe-hydrogen.Ngemuva kokuthi amafutha e-oxidized, azothinta ukuzinza kwesakhiwo sekhebula le-optical, okuholela ekunciphiseni kokucindezeleka.Ngale ndlela, ikhebula le-OPGW optical lizothinteka ngenxa ye-oscillation, umthelela, i-tortuous, umehluko wezinga lokushisa, kanye ne-topography.Ngaphansi kwengcindezi, umthelela wokubhafa we-fiber paste kukhebuli yokubona uba buthakathaka, ngaleyo ndlela kunciphisa ukuphepha kwekhebuli yokubona ye-OPGW.Ukuxhumana okuqondile phakathi kwe-fiber paste nekhebula le-OPGW kuyimbangela eqondile yokuwohloka komsebenzi wentambo ye-fiber optic.I-fiber paste izowohloka kancane ngokuhamba kwesikhathi, imvamisa iqala inqwabelana ibe yizinhlayiya ezincane, bese iyahwamuka kancane kancane, ihlukanise, futhi yome.
3. Ukukhethwa kwezinto ezibonakalayo kanye nenqubo yokudweba ucingo ye-optical cable coating
Izizathu eziyinhloko zokulahlekelwa okukhulayo kwekhebuli ye-OPGW esebenzayo zihlanganisa ukulahleka kwe-hydrogen, ukuqhekeka kwekhebula, nokucindezeleka kwekhebula.Ngemva kokuhlolwa okungokoqobo, kutholakala ukuthi ngemva kweminyaka yokusetshenziswa, izici zemishini, izici ze-splice, nezici zokubona zekhebula le-OPGW azikashintshi.Ngemva kokuskena, I-electron microscope yathola ukuthi ikhebula lokubona alinazo izinto ezisobala ezingavamile njengama-micro-cracks.Kodwa-ke, kuye kwaphawulwa ukuthi ukumbozwa kwekhebula le-OPGW akukuhle, futhi ukuncishiswa kwekhebula le-optical nge-modulus ephezulu, ukunamathela okuqinile namandla amakhulu okuxebula kuzoba sobala kakhulu.
Ekusetshenzisweni kwangempela, ikhebuli yokubona kungenzeka ibe nokuhluleka okuthile ngenxa yezizathu ezithile zangaphandle noma izinkinga zekhwalithi.Ngakho-ke, uma ufuna ukuyisebenzisa isikhathi eside, kufanele ifaneleke ngokobuchwepheshe.Ikhwalithi yizwi lokugcina.
