Imingcele yezobuchwepheshe yezintambo ze-OPGW ne-ADSS zinezicaciso zikagesi ezihambisanayo.Amapharamitha womshini wekhebula le-OPGW nekhebula le-ADSS ayafana, kodwa ukusebenza kukagesi kuhlukile.
1. Ilinganiselwe amandla e-tensile-RTS
Okwaziwa nangokuthi amandla okugcina aqinile noma amandla okuphuka, kubhekisela enanini elibaliwe lesamba samandla esigaba esithwala umthwalo (i-ADSS ibala ngokuyinhloko ifayibha ejikelezayo).Ekuhlolweni kwamandla okuphuka, noma iyiphi ingxenye yekhebula ibhekwa njengephukile.I-RTS iyipharamitha ebalulekile yokucushwa kokufakwayo (ikakhulukazi i-tension clamp) kanye nokubalwa kwesici sokuphepha.
2. Amandla aphezulu avumelekile we-tensile-MAT
Le parameter ihambisana nokushuba okuphezulu kwe-OPGW noma i-ADSS uma isamba somthwalo sibalwa ngokwethiyori ngaphansi kwezimo zezulu zokuklama.Ngaphansi kwalokhu kushuba, kufanele kuqinisekiswe ukuthi i-fiber ayinaso ingcindezi futhi ayinakho ukuncishiswa okwengeziwe.Ngokuvamile i-MAT icishe ibe ngu-40% we-RTS.
I-MAT iyisisekelo esibalulekile sokubala nokulawula ukuhlehla, ukushuba, ubude besikhathi kanye nesici sokuphepha.
3. I-avareji yansuku zonke ye-tension-EDS
Eyaziwa nangokuthi i-avareji ye-avareji yokusebenza yonyaka, ukushuba okumaphakathi okutholwa i-OPGW ne-ADSS phakathi nokusebenza kwesikhathi eside.Ihambisana nokubala kwethiyori kokungezwani ngaphansi kwezimo zokungabikho komoya, iqhwa kanye nezinga lokushisa elijwayelekile lonyaka.I-EDS ngokuvamile ingu-16% kuya ku-25% we-RTS.
Ngaphansi kwalokhu kushuba, ikhebuli ye-OPGW ne-ADSS kufanele imelane nokuhlolwa kokudlidliza okubangelwa umoya, i-fiber optical kukhebula kufanele izinze kakhulu, futhi izinto nezinto ezisetshenziswayo kufanele kungabi nomonakalo.
4. Umkhawulo wobunzima
Ngezinye izikhathi kuthiwa yi-tension ekhethekile yokusebenza, ngokuvamile kufanele ibe ngaphezu kuka-60% we-RTS.Ngokuvamile ngemva kokuba amandla ekhebula le-ADSS optical edlula i-MAT, i-fiber optical iqala ukucindezeleka futhi ukulahlekelwa okwengeziwe kwenzeka, kuyilapho i-OPGW isengakwazi ukugcina i-fiber optical strain-free futhi akukho ukulahlekelwa okwengeziwe kuze kube inani lomkhawulo wobunzima (kuye ngokuthi isakhiwo. ).Kodwa noma ngabe ikhebula le-OPGW noma i-ADSS optical, kuyadingeka ukuthi i-optical fibre kufanele iqinisekiswe ukuthi ibuyela esimweni sokuqala ngemva kokukhishwa kwe-tension.
5. DC ukumelana
Ibhekisela enanini elibaliwe lokumelana okuhambisanayo kwazo zonke izici ze-conductive ku-OPGW ku-20°C, okufanele isondele ngangokunokwenzeka kwentambo yaphansi ephambene ohlelweni lwezintambo ezimbili eziphansi.I-ADSS ayinayo imingcele nezimfuneko ezinjalo.
6. Isifunda esifushane samanje
Isho ubuningi bamanje i-OPGW engakwazi ukumelana nayo ngaphakathi kwesikhathi esithile (ngokuvamile, isigaba esisodwa ukuya phansi) sesifunda esifushane.Esibalweni, amanani esikhathi samanje sesifunda esifushane kanye nezinga lokushisa lokuqala nelokugcina anomthelela emiphumeleni, futhi amanani kufanele asondele kakhulu ezimweni zokusebenza zangempela.I-ADSS ayinayo inombolo enjalo nezimfuneko.
7. Umthamo wamanje wesifunda esifushane
Kubhekiselwa kumkhiqizo wesikwele se-short-circuit current kanye nesikhathi, okungukuthi, i-I²t.I-ADSS ayinayo imingcele nezimfuneko ezinjalo.
