Iintambo zokukhanya ze-ADSS sebenza kwisithuba esikhulu senkxaso yamanqaku amabini (idla ngokuba ngamakhulu eemitha, okanye nangaphezulu kwe-1km) ngaphezulu komgangatho, owahluke ngokupheleleyo kwingqikelelo yesiqhelo ye-overhead (iposi kunye nenkqubo yonxibelelwano oluqhelekileyo olujingayo lwentambo yocingo, umyinge we-0.4 yeemitha kwintambo ye-optical 1 Fulcrum).Ngoko ke, iiparameters eziphambili ze-ADSS ze-optical cables zihambelana nemimiselo yemigqaliselo yamandla ombane.
1. Umlinganiselo wamandla okuqina (UTS/RTS)
Ekwaziwa njengamandla okugqibela okanye amandla okuqhawula, ibhekisa kwixabiso elibaliweyo lesambuku samandla ecandelo elithwele umthwalo (ikakhulu libalwa njengefiber ejikelezayo).Amandla okwenene aqhekezayo kufuneka abe mkhulu okanye alingane ne-95% yexabiso elibalwe (ikhefu lalo naliphi na icandelo kwi-cable optical lithathwa njengekhefu).Le parameter ayikhethi.Amaxabiso amaninzi olawulo anxulumene nayo (njengamandla enqaba, i-tensile hardware, imilinganiselo yokuchasana nokungcangcazela, njl.njl.).Kubasebenzi be-fiber optic cable, ukuba umlinganiselo we-RTS/MAT (olingana nokhuseleko lwe-K yemigca engaphezulu) ayifanelekanga, oko kukuthi, ukuba kusetyenziswe imicu emininzi esontiweyo kwaye uluhlu olukhoyo lwefiber strain lumxinwa kakhulu. Umlinganiselo wokusebenza kwezoqoqosho/kwezobugcisa usezantsi kakhulu.Ke ngoko, umbhali ucebisa ukuba abangaphakathi kwishishini banikele ingqalelo kule parameter.Ngokubanzi, iMAT iphantse ilingane ne-40% ye-RTS.
2. Ubuninzi boxinzelelo obuvumelekileyo (MAT/MOTS)
Kubhekiselele kuxinzelelo kwintambo ye-optical xa umthwalo uphelele ubalwa ngokwethiyori phantsi kweemeko zemozulu zoyilo.Ngaphantsi kolu xinzelelo, i-fiber strain kufuneka ibe ngu-≤0.05% (i-stranded) kunye ne-≤0.1% (i-tube ephakathi) ngaphandle kokunciphisa okongeziweyo.Ngokwemigaqo ye-layman, ubude obugqithisileyo be-fiber optical buye batyiwa kweli xabiso lolawulo.Ngokwale parameter, iimeko zemeteorological kunye ne-sag elawulwayo, ixesha elivumelekileyo lekhebula le-optical lingabalwa phantsi kwalo mqathango.Ke ngoko, i-MAT isisiseko esibalulekileyo sokubala i-sag-tension-span, kwaye ikwabubungqina obubalulekileyo bophawu lweempawu zoxinzelelo lweentambo ze-ADSS.
3. Umndilili woxinzelelo wonyaka (EDS)
Ngamanye amaxesha kuthiwa yi-avareji yoxinzelelo lwemihla ngemihla, ibhekisa kuxinzelelo olubalwe ngokwethiyori yentambo yokukhanya phantsi komthwalo phantsi komoya, akukho mkhenkce kunye nobushushu obuphakathi bonyaka.Inokuthathwa njengoxinzelelo oluphakathi (uxinzelelo) lwe-ADSS ngexesha lokusebenza kwexesha elide.I-EDS ngokubanzi yi-(16~25)%RTS.Ngaphantsi kolu xinzelelo, i-fiber optical ayifanele ibe noxinzelelo kwaye ingabikho i-attenuation eyongezelelweyo, oko kukuthi, izinzile kakhulu.I-EDS yiparameter yokuguga yokukhathala kwentambo ye-optical ngexesha elifanayo, ngokuhambelana nale parameter inquma i-anti-vibration design ye-cable optical.
4. Uxinzelelo oluphezulu lokusebenza (UES)
Eyaziwa nangokuthi ukuxhatshazwa kokusetyenziswa okukhethekileyo, kubhekiselele kuxinzelelo oluphezulu lwentambo ye-optical enokugqithisa umthwalo woyilo ngexesha lobomi obusebenzayo bekhebula le-optical cable.Kuthetha ukuba ikhebula le-optical livumela ukugqithiswa kwexesha elifutshane, kwaye i-fiber optical inokumelana noxinzelelo ngaphakathi kwinqanaba elivumelekileyo.Ngokubanzi, i-UES kufuneka ibe ngaphezulu kwama-60% e-RTS.Ngaphantsi kolu xinzelelo, ukuba ubunzima befiber bungaphantsi kwe-0.5% (ityhubhu ephakathi) kwaye ngaphantsi kwe-0.35% (i-stranded), i-attenuation eyongezelelweyo yefiber iya kwenzeka, kodwa emva kokukhutshwa koxinzelelo, i-fiber kufuneka ibuyele ngokuqhelekileyo.Le parameter iqinisekisa ukusebenza okuthembekileyo kwekhebula le-ADSS optical ngexesha lokuphila kwayo.
