I-All-dielectric self-supporting (ADSS) intambo luhlobo lwentambo yefiber optical eyomeleleyo ngokwaneleyo ukuzixhasa phakathi kwezakhiwo ngaphandle kokusebenzisa izinto zetsimbi eziqhubayo.Isetyenziswa ziinkampani eziluncedo zombane njengendawo yonxibelelwano, efakwe ecaleni kwemigca yothumelo engaphezulu esele ikhona kwaye ihlala isabelana ngenkxaso efanayo njengeekhondaktha zombane.
Kwihlabathi lonxibelelwano, ukusetyenziswa kweIintambo ze-All-Dielectric Self-Support (ADSS).iye yathandwa kakhulu ngenxa yokuguquguquka kunye nokuqina kwayo.Nangona kunjalo, ukuyila kunye nokuvelisa intambo ye-ADSS efanelekileyo kunokuba yinkqubo enzima kunye nomngeni.
Eyona nto ibalulekileyo uyilo loKwakha
Ukuze uyilwe ngokufanelekileyo ubume bentambo ye-ADSS, imiba emininzi kufuneka ithathelwe ingqalelo.Kubandakanya amandla oomatshini, i-conductor sag, Isantya somoya b ubukhulu bomkhenkce c ubushushu be-d topography, i-Span, i-Voltage.
Ngokuqhelekileyo, xa usenza imveliso, kufuneka uqwalasele le mibuzo ilandelayo.
Uhlobo lwebhatyi:AT/PE
I-PE sheath: i-sheath ye-polyethylene eqhelekileyo.Ngeentambo zamandla ezingaphantsi kwe-110KV, kunye ne-≤12KV amandla ebala lombane.Intambo kufuneka imiswe kwindawo apho amandla ombane amancinci.
I-AT sheath: i-sheath anti-tracking.Ngeentambo zamandla ezingaphezulu kwe-110KV, ≤20KV amandla ebala lombane.Intambo kufuneka imiswe kwindawo apho amandla ombane amancinci.

RTS: Ilinganiswe amandla okuqina
Ibhekisela kwixabiso elibaliweyo lamandla ecandelo lokuthwala (ikakhulukazi ukubala i-fiber ejikelezayo).
I-UTS: Amandla e-Ultimate Tensile UES>60% RTS
Kubomi obusebenzayo bekhebula, kunokwenzeka ukuba ugqithise umthwalo woyilo xa ikhebula ngoxinzelelo oluphezulu.Oko kuthetha ukuba ikhebula linokugqithisa ixesha elifutshane.
MAT: Uxinzelelo oluphezulu oluvumelekileyo lokusebenza 40% RTS
I-MAT sisiseko esibalulekileyo se-sag - tension - span calculation, kunye nobungqina obubalulekileyo bokubonakalisa iimpawu ze-stress-strain ze-ADSS optical cable.Ibhekisela kuyilo lweemeko zemeteorological phantsi kokubala kwethiyori yomthwalo opheleleyo, ukuxhatshazwa kwentambo.
Ngaphantsi kolu xinzelelo, i-fiber strain akufanele ibe ngaphezu kwe-0.05% (i-laminated) kwaye ingabi ngaphezu kwe-0.1% (ipayipi ephakathi) ngaphandle kokunciphisa okongeziweyo.
I-EDS: Yonke imihla Amandla (16 ~ 25)% RTS
Uxinzelelo lwe-avareji yonyaka ngamanye amaxesha kuthiwa yi-avareji yoxinzelelo lwemihla ngemihla, ibhekisa emoyeni kwaye akukho mkhenkce kunye nobushushu obuphakathi konyaka, ukubalwa kwethiyori yoxinzelelo lwentambo yomthwalo, inokuthathwa njenge-ADSS ekusebenzeni kwexesha elide loxinzelelo oluphakathi. (kufuneka) ngenkani.
I-EDS ngokubanzi yi-(16~25) %RTS.
Ngaphantsi kolu xinzelelo, i-fiber kufuneka ingabi naxinzelelo, ingabikho ukuthotywa okongeziweyo, oko kukuthi, izinzile kakhulu.
I-EDS ikwayipharamitha yokudinwa kwe-fiber optic cable, ngokubhekiselele kuyilo oluchasene nokungcangcazela kwentambo ye-fiber optic optic.
Isishwankathelo, ukuyila kunye nokuvelisa intambo ye-ADSS efanelekileyo idinga ukuqonda ngokucokisekileyo iimfuno zeprojekthi, ukukhethwa kwezinto eziphezulu, kunye nokuphunyezwa kwamanyathelo okulawula umgangatho oqinileyo.Benale ngqwalasela engqondweni, ababoneleli bonxibelelwano ngomnxeba banokufaka ngokuzithemba iintambo ze-ADSS ezihlangabezana neemfuno zanamhlanje zoqhagamshelwano.
