OPGW FAQS
Abalingane bentambo ye-Optical, ukuba nabani na ubuza ukuba yintoniOPGW intambo yokubonayi, nceda uphendule ngolu hlobo:
1. Ziziphi izakhiwo eziqhelekileyo zeentambo ze-optical?
Isakhiwo sekhebula eliqhelekileyo lekhebula le-optical cable lineentlobo ezimbini ze-stranded type kunye ne-skeleton type.
2. Yeyiphi eyona nto iphambili?
Intambo ye-optical iqulunqwe ngokukodwa: i-fiber core, i-fiber optical grease, i-sheath material, i-PBT (i-polybutylene terephthalate) kunye nezinye izinto.
3.Yintoni isikrweqe sentambo yokukhanya?
Ukuxhotyiswa kwentambo ye-optical kubhekiselele kwinto ekhuselayo (ngokuqhelekileyo ucingo lwentsimbi okanye iteyiphu yensimbi) esetyenziswa kwiintambo zokukhanya ezikhethekileyo (ezifana neentambo ze-submarine optical, njl. njl.).Isikrweqe sifakwe kwi-sheath yangaphakathi yentambo ye-optical.
4. Yeyiphi imathiriyeli esetyenziselwa i-cable sheath?
I-sheath okanye umaleko wentambo ye-optical idla ngokuqulunqwa nge-polyethylene (PE) kunye ne-polyvinyl chloride (PVC) izinto, kwaye umsebenzi wayo kukukhusela i-core cable kwiimpembelelo zangaphandle.
5. Ziziphi iintambo ezikhethekileyo zamehlo ezisetyenziswa kwiinkqubo zamandla?
Kukho ubukhulu becala iintlobo ezintathu zeentambo ezikhethekileyo ezisetyenziswa kwiinkqubo zamandla: intambo yomhlaba edibeneyo ye-optical cable (OPGW), intambo yenxeba ye-optical (GWWOP), kunye ne-self-supporting optical cable (ADSS).
Intambo yomhlaba edibeneyo ye-optical cable (OPGW), i-fiber optical ifakwe kumgca wamandla we-steel-clad aluminium strand structure.Ukusetyenziswa kwentambo ye-OPGW optical idlala umsebenzi ombini wokumisa kunye nokunxibelelana, ukuphucula ngokufanelekileyoIzinga lokusetyenziswa kweepali zombane liyenyuka.Intambo ye-optical esongiweyo (GWWOP), apho kukho umgca wokuhambisa amandla, intambo ye-optical inxeba okanye inqunyanyiswe kwintambo yomhlaba.Ndivile ukuba i-6-core optical cable ibiza kakhulu kune-6-core optical cable, ukuba ufuna ukuqonda ngakumbi.Intambo yombane ozixhasayo (ADSS) inamandla okuqina okuqina kwaye inokuxhonywa ngokuthe ngqo phakathi kweepali zamandla ezimbini ezinobude bexesha ukuya kuthi ga kwi-1500m.
6. Ziziphi izakhiwo zokusetyenziswa kweentambo ze-OPGW optical cable?
Ubume besicelo se-OPGW intambo ye-optical cable ibandakanya ikakhulu: i-tube yeplastiki ye-tube edibeneyo + i-aluminium yesakhiwo setyhubhu, ityhubhu yeplastiki ephakathi + isakhiwo setyhubhu ye-aluminium, isakhiwo samathambo e-aluminium, isakhiwo setyhubhu ye-aluminium ejikelezayo, umaleko omnye.Ulwakhiwo lombhobho wentsimbi erulileyo, umbindi wesakhiwo semibhobho yentsimbi, umbhobho wentsimbi engatyiwayo , isakhiwo sombhobho wentsimbi edibeneyo, isakhiwo semibhobho yentsimbi esomeleleyo, umbhobho wentsimbi engenamaleko.
7. Yintoni eyona nto iphambili yocingo olufakwe ngaphandle kwentambo yentambo?
I-wire stranded ngaphandle kombindi we-OPGW optical cable iqulunqwe kakhulu yi-AA wire (i-aluminium alloy wire) kunye ne-AS wire (i-aluminium clad steel wire).
8. Ziziphi iimeko zobugcisa zokukhetha imodeli yentambo ye-OPGW?
1) Amandla e-nominal tensile (RTS) (kN) ye-OPGW intambo yokubona;
2) Inani le-fiber cores (SM) yentambo ye-OPGW;
3) Umsinga omfutshane (kA);
4) Ixesha elifutshane lesekethe (ama);
5) Uluhlu lobushushu (℃).
9.Indlela yokunciphisa iqondo lokugoba lentambo yokukhanya?
I-radius yokugoba yentambo ye-optical ayifanele ibe ngaphantsi kwamaxesha angama-20 ububanzi obungaphandle bekhebula le-optical cable, kwaye ngexesha lenkqubo yokwakha (imeko engasimiyo) engekho ngaphantsi kwamaxesha angama-30 ububanzi obungaphandle bekhebula le-optical cable.
10. Yintoni ekufuneka iqwalaselwe kwiprojekthi?
Kukho iitekhnoloji ezintathu eziphambili kwi-ADSS optical cable engineering: i-optical cable design mechanical, ukuzimisela kwamanqaku okunqunyanyiswa, kunye nokukhetha kunye nokufakwa kwe-hardware exhasayo.
11. Ziziphi ezona zixhobo ziphambili zokufakelwa kwentambo yokukhanya?
Ukufakwa kwentambo ye-Optical ibhekisa kwi-hardware esetyenziselwa ukufakela intambo yokukhanya, ngakumbi kubandakanya: i-strain clamp, i-suspension clamp, i-vibration isolator, njl.
