Iiparamitha zobugcisa ze-OPGW kunye neentambo ze-ADSS zineenkcazo zombane ezihambelanayo.Iiparamitha zemishini ye-OPGW cable kunye nekhebula le-ADSS ziyafana, kodwa ukusebenza kombane kuyahluka.
1. Umlinganiselo wokuqina wokuqina-RTS
Ekwaziwa njengamandla okugqibela okanye amandla okuqhawuka, ibhekisa kwixabiso elibaliweyo lesambuku samandla ecandelo elithwele umthwalo (ADSS ikakhulu ibala ifayibha ejikelezayo).Kuvavanyo lwamandla okuqhawula, nayiphi na inxalenye yentambo igwetywa ukuba yaphukile.I-RTS iyipharamitha ebalulekileyo yokucwangciswa kwezinto zokufakelwa (ingakumbi i-tension clamp) kunye nokubalwa kwezinto ezikhuselekileyo.
2. Ubuninzi obuvumelekileyo bokuqina bokuqina-MAT
Le parameter ihambelana noxinzelelo olukhulu lwe-OPGW okanye i-ADSS xa umthwalo uphelele ubalwa ngokwethiyori phantsi kweemeko zemozulu zoyilo.Ngaphantsi kolu xinzelelo, kufuneka kuqinisekiswe ukuba i-fiber ayinaxinzelelo kwaye ayinayo i-attenuation eyongezelelweyo.Ngokwesiqhelo iMAT imalunga nama-40% e-RTS.
I-MAT sisiseko esibalulekileyo sokubala kunye nokulawula i-sag, i-tension, i-span kunye nemeko yokhuseleko.
3. I-avareji yemihla ngemihla yokubaleka i-tension-EDS
Ikwabizwa ngokuba yi-avareji yoxinzelelo lokusebenza ngonyaka, yi-avareji yoxinzelelo olufunyanwa yi-OPGW kunye ne-ADSS ngexesha lokusebenza kwexesha elide.Ihambelana nokubala kwethiyori yoxinzelelo phantsi kweemeko zomoya, umkhenkce kunye nobushushu obuphakathi bonyaka.I-EDS ngokuqhelekileyo yi-16% ukuya kwi-25% ye-RTS.
Ngaphantsi kolu xinzelelo, intambo ye-OPGW kunye ne-ADSS kufuneka imelane novavanyo lwe-vibration olubangelwa ngumoya, i-fiber optical kwintambo kufuneka izinzile kakhulu, kwaye izinto kunye nezixhobo ezisetyenzisiweyo kufuneka zikhululeke kumonakalo.
4. Umda woxinzelelo
Ngamanye amaxesha kuthiwa kuxinzelelo olukhethekileyo lokusebenza, kufuneka ngokubanzi lube ngaphezulu kwe-60% ye-RTS.Ngokuqhelekileyo emva kokunyanzeliswa kwentambo ye-ADSS ye-optical idlula i-MAT, i-fiber optical iqala ukunyanzeliswa kwaye ilahleko eyongezelelweyo iyenzeka, ngelixa i-OPGW isenako ukugcina i-fiber optical strain-free kwaye akukho lahleko eyongezelelweyo kuze kube yilapho ixabiso lomda wobunzima (kuxhomekeke kwisakhiwo. ).Kodwa nokuba i-OPGW okanye i-ADSS intambo ye-optical, iyafuneka ukuba i-fiber optical kufuneka iqinisekiswe ukuba ibuyele kwimeko yokuqala emva kokukhululwa kwengcinezelo.
5. DC ukuxhathisa
Ibhekisela kwixabiso elibaliweyo lokuchasana okuhambelanayo kuzo zonke izinto eziqhubayo kwi-OPGW kwi-20 ° C, ekufuneka isondele ngokusemandleni kwi-wire yomhlaba ochaseneyo kwindlela yocingo oluphantsi komhlaba.I-ADSS ayinayo iparameters kunye neemfuno.
6. Isiphaluka esifutshane sangoku
Ibhekiselele kubuninzi bangoku i-OPGW enokumelana nayo ngexesha elithile (ngokubanzi, isigaba esinye ukuya phantsi) ixesha elifutshane lesekethe.Ekubaleni, amaxabiso exesha langoku le-short-circuit kunye neqondo lobushushu lokuqala kunye nelokugqibela linempembelelo kwiziphumo, kwaye amaxabiso kufuneka asondele kangangoko kunokwenzeka kwiimeko zokwenyani zokusebenza.I-ADSS ayinayo inombolo kunye neemfuno.
7. Umthamo wangoku wesekethe emfutshane
Ibhekisa kwimveliso yesikwere sesekhethi emfutshane yangoku kunye nexesha, oko kukuthi, I²t.I-ADSS ayinayo iparameters kunye neemfuno.
