All-dielectric self-supporting (ADSS) fiilada waa nooc ka mid ah fiilada indhaha ee ku filan si ay isu taageerto inta u dhaxaysa dhismayaasha iyada oo aan la isticmaalin walxo bir ah.Waxa ay u isticmaalaan shirkadaha tamarta korantada oo ah isgaarsiin ahaan, oo lagu rakibay xadhkaha gudbinta sare ee jira oo inta badan la wadaaga dhismooyin taageero oo la mid ah kuwa korantada.
Dunida isgaarsiinta, isticmaalkaAll-Dielectric Self-Supporting (ADSS) fiilooyinkawaxa ay noqdeen kuwo si isa soo taraya caan u noqday badelkooda iyo adkaysigooda.Si kastaba ha ahaatee, naqshadaynta iyo soo saarista fiilada ADSS ee saxda ah waxay noqon kartaa hawl adag oo adag.
Naqshadaynta ugu muhiimsan ee dhismaha
Si loo qaabeeyo qaab dhismeedka fiilada ADSS, dhinacyo badan ayaa loo baahan yahay in laga fiirsado.
Sida caadiga ah, marka aad ku jirto wax soo saarka, waxaad u baahan tahay inaad tixgeliso su'aalaha soo socda.
Nooca Jaakada: AT/PE
Galka PE: Galka polyetylenka caadiga ah.Xadhkaha korantada ee ka hooseeya 110KV, iyo ≤12KV xoogga goobta korantada.Fiilada waa in lagu hakiyaa meel ay xoogga korontadu ku yar tahay.
Galka: Galka ka-hortagga raadraaca.Xadhkaha korantada ee ka sarreeya 110KV, ≤20KV xoogga goobta korantada.Fiilada waa in lagu hakiyaa meel ay xoogga korontadu ku yar tahay.

RTS: La qiimeeyay xoogga xajinta
Waxa loola jeedaa qiimaha la xisaabiyay ee xoogga qaybta wax-qaadista (badanaa tirinta fibre-wareega).
UTS: UES> 60% RTS
Nolosha wax ku oolka ah ee fiilada, waxaa suurtagal ah in la dhaafo culeyska naqshadeynta marka fiilada ay ku jirto xiisadda ugu badan. Taas macnaheedu waa fiilada waxaa lagu kordhin karaa wakhti gaaban
MAT: Ugu badnaan xiisadda shaqada ee la oggol yahay 40% RTS
MAT waa saldhig muhiim ah oo loogu talagalay sag - xiisad - xisaabinta taako, iyo sidoo kale caddayn muhiim ah oo lagu garto sifooyinka cadaadiska cadaadiska ADSS ee fiilada indhaha.
Xiisadan hoosteeda, cadaadiska fiberku waa in aanu ka badnayn 0.05% (laminated) iyo in aanu ka badnayn 0.1% (tuubada dhexe) iyada oo aan la yarayn dheeraad ah.
EDS: Xoog Maalin kasta (16 ~ 25)% RTS
Cadaadiska celceliska sanadlaha ah waxaa mararka qaarkood loo yaqaan cadaadiska celceliska maalinlaha ah, waxaa loola jeedaa dabaysha oo aan lahayn baraf iyo heerkulka celceliska sanadlaha ah, xisaabinta fekerka ee culeyska culeyska, waxaa loo tixgelin karaa ADSS ee hawlgalka muddada dheer ee celceliska xiisadda. (waa) xoog.
EDS guud ahaan waa (16 ~ 25)% RTS.
Xiisadan hoosteeda, fiber-ku waa inuu lahaadaa wax cadaadis ah, ma jiro wax yar oo dheeraad ah, taas oo ah, aad u deggan.
EDS sidoo kale waa qiyaasta gabowga daalka ee fiilada fiber optic-ga, marka loo eego naqshadeynta ka-hortagga gariirka ee fiilada fiber optic-ga lagu go'aamiyo.
Isku soo wada duuboo, qaabaynta iyo soo saarista xadhiga ADSS ee saxda ah waxay u baahan tahay in si fiican loo fahmo shuruudaha mashruuca, xulashada agab tayo sare leh, iyo hirgelinta tilaabooyinka xakamaynta tayada adag.Iyadoo tixgalintan maskaxda lagu hayo, bixiyeyaasha isgaarsiintu waxay si kalsooni leh u diri karaan fiilooyinka ADSS kuwaas oo buuxinaya baahida isku xirnaanta maanta.
