Ngexesha lokufakela umgca wothumelo, ukukhetha iintambo ezinokumelana neengozi zendalo ezifana nezaqhwithi, imvula, njl., kunyanzelekile. Ngaphezu koko, kufuneka bomelele ngokwaneleyo ukuxhasa ubude bofakelo.
Kunye naloo nto, njengenyathelo lokhuseleko, kufuneka ujonge umgangatho wemveliso kunye nokuqina. Ukugcina zonke ezi zinto engqondweni, ezona zisetyenziswa kakhulu ziintambo ze-OPGW. Kwaye, ukuba umntu ujonge enye indlela, iintambo ze-ADSS ziya kuba lukhetho olufanelekileyo.
Kodwa, apha, umbuzo uvela - yintoni engcono? OPGW okanye ADSS?
Intambo ye-OPGW-Optical Ground Wire
Ukwenziwa kwezi ntambo kusekelwe kwimisebenzi emibini: i-conductor yasemoyeni kunye neyunithi edibeneyo ye-fiber-optic. Apha kukho umahluko - umqhubi we-aerial ukhusela abaqhubi ekukhanyeni.
Ngaphandle koko, i-OPGW ye-fiber optics edibeneyo ibonelela ngendlela yonxibelelwano ngonxibelelwano lomntu wesithathu, kubandakanywa nangaphakathi. Yintambo esebenza kabini kwaye iyindawo edumileyo yokutshintshwa kweengcingo zomhlaba okanye iingcingo zemveli ezimileyo. Ufakelo lwezixhobo ze-OPGW ziyafumaneka kwaye kulula ukuzifaka.
Ukuba sihamba ngokomgangatho we-IEEE (Iziko leeNjineli zoMbane neze-Eletroniki), ikwabizwa ngokuba yi-optical fiber composite yocingo olungaphezulu komhlaba. Yenzelwe ukudibanisa imisebenzi yokumisa kunye nonxibelelwano. Unokusebenzisa ezi ntambo xa kukho imfuneko enzulu yokutshintsha ucingo olukhoyo lomhlaba olufuna ukutshintshwa ngokukhawuleza.
Ikhebula le-ADSS-I-All-Dielectric Self-Supporting
Ezi ntambo ze-optical zomelele ngokwaneleyo ukuxhasa isakhiwo semigca yokuhambisa kwaye ilungele ukuhanjiswa. Ngaphezu koko, inokumelana neentlekele zemvelo kunye neengozi zendalo. Oku kwenza kube lukhetho olungcono kakhulu xa kuthelekiswa nezinye iintambo.
Le yintambo engeyiyo intsimbi, kwaye akukho mfuneko yokuqhawula iingcingo ukuyixhasa ngaphandle. Inzuzo enkulu kukuba ungabeka ezi ntambo kwi-conduit. Ufakelo lweentambo ze-ADSS kumgca wothumelo okhoyo wenza ukuba kungabizi kakhulu. Ngaphezu koko, iphinde izimele kwiintambo zombane kwaye ibonelela ngenkxaso ngokulungiswa.
OPGW vs ADSS-Ngowuphi umahluko?
OPGW (Optical Ground Wire)
Izinto eziluncedo kwiiNdlela zoThumelo oluPhezulu:
Ukusebenza kabini:I-OPGW isebenza zombini njengocingo lokumisa kunye nesixhobo sonxibelelwano, nto leyo eyenza ukuba ilungele iintambo zothumelo lwe-voltage ephezulu.
Ukubeka phantsi:Ibonelela ngendlela yokubetha umbane kunye nemisinga yempazamo, ukukhusela isiseko sothungelwano lombane.
Amandla oomatshini:Izixhobo zetsimbi zinika amandla aphezulu, okuyimfuneko kwixesha elide kunye neendawo ezinomoya ophezulu okanye ukulayishwa kweqhwa.
Usetyenziso oluqhelekileyo:
IiNdlela zoThutho lweVoltage ephezulu:I-OPGW isoloko isetyenziselwa ukufakelo olutsha okanye ukuphuculwa kweentambo zothumelo lwe-voltage ephezulu apho zombini isiseko kunye nonxibelelwano luyimfuneko.
Iziseko ezingundoqo ezikhoyo:Ilungele ukuphuculwa kwemigca ekhoyo apho kudityaniswa isiseko kunye nonxibelelwano kufuneka.
Imingeni:
Ubunzima boFakelo: Ifuna ukuvalwa kwentambo yombane ngexesha lofakelo okanye ulungiso, olunokuba ngumceli mngeni ngokwenkqubo kunye neendleko.
Ukhuseleko: Ukuphatha kufutshane neentambo zombane eziphilayo kunokuba yingozi, kufuna ucwangciso olunenkathalo kunye nokuphunyezwa.
I-ADSS (I-Dielectric Self-Supporting)
Izinto eziluncedo kwiiNdlela zoThumelo oluPhezulu:
Ukhuseleko: Zenziwe ngokupheleleyo ngezinto ze-dielectric, iintambo ze-ADSS zikhuselekile ukuba zifakwe kufuphi neentambo zombane eziphilayo, zisusa umngcipheko weengozi zombane.
Ukulula ukuFakela: Inokufakwa ngaphandle kokuvala iintambo zombane, ukunciphisa ukuphazamiseka kokusebenza kunye neendleko zokufakela.
Ukuguquguquka: Ilungele iindawo ezahlukeneyo, kubandakanya iindawo ezinokuphazamiseka okuphezulu kombane, ngenxa yokungaqhubi.
Usetyenziso oluqhelekileyo:
Uthungelwano losasazo:I-ADSS ilungele uthungelwano losasazo oluphakathi ukuya kwi-low-voltage apho isiseko singeyiyo eyona nkxalabo iphambili.
Uphuculo loNxibelelwano:Isetyenziswa kwiimeko apho iintambo zombane ezikhoyo kufuneka ziphuculwe ngezakhono zonxibelelwano ngaphandle kokuphazamisa ukunikezelwa kwamandla.
Imingeni:
Kuyafuneka ukwahlulwa komhlaba okwahlukileyo:Ekubeni i-ADSS ayiboneleli ngesiseko, izisombululo ezongezelelweyo ziyafuneka kwisiseko, esinokuthi songeze ubunzima kunye neendleko.
Amandla oomatshini:Ngelixa i-ADSS ineempawu ezilungileyo zoomatshini, isenokungomelelanga njenge-OPGW ixesha elide kakhulu okanye iimeko ezirhabaxa zokusingqongileyo.
Ukuqukumbela
Ukukhetha iintambo ezigqibeleleyo zeentambo zothumelo ezihamba phezulu kunokubhideka. Ke, kuya kufuneka ubambelele kwimiba ephambili efana noyilo lwekheyibhuli, indawo esingqongileyo kunye neendleko zofakelo. Ukuba ujongene neentambo ezintsha kwaye kufuneka wakhe yonke inkqubo yothumelo ukusuka ekuqaleni, ngoko i-OPGW iya kufaneleka.
Nangona kunjalo, ukuba ujongene neepali zecabling esele zikhona, i-ADSS iya kusebenza ngcono njengekheyibhuli yangaphandle. Ngoko ke, bamba iintambo ezisemgangathweni kunye nocingo oluvela kwi-GL FIBER, igama elithembekileyo ekunikezeni i-ADSS kunye ne-OPGW fittings iminyaka engama-20 +.
