Intambo ye-ADSS ifakelwe kwiimitha ezili-10 ukuya kwezingama-20 (3m ukuya kwezingama-6m) ngaphantsi kwee-phase conductors. Ii-armor rod assemblies ezisekelwe phantsi zixhasa intambo ye-fiber-optic kwisakhiwo ngasinye esixhasayo. Izixhobo zibike ukusilela kwe-ADSS efakwe kwiintambo zazo eziphezulu zombane. Intsimi yombane ephezulu kwiintambo zothumelo ivelisa ukukhutshwa kwe-corona okuqhubekayo ekupheleni kweentambo zokuxhasa. Oku kukhutshwa kukhokelela ekuwohlokeni kweentambo. Kwiindawo ezingcolisekileyo, ukugoba kwebhendi eyomileyo kubangela ukonakala kweentambo xa inkungu okanye umbethe ngamanye amaxesha imanzisa intambo. Ulindelo lobomi be-ADSS kwiintambo zombane luxhomekeke kwezi zinto zilandelayo:

Zombane

Isiphumo seCorona

Ukubetha ngebhendi eyomileyo

Isiphumo esinokubakho sendawo

Oomatshini

Ubude bespan kunye nokugoba

Uxinzelelo kwiintambo

Okusingqongileyo

Isantya somoya kunye nokungcangcazela kwe-Aeolian

Ukwakheka kwesingxobo sokuxhathisa i-UV (i-UV evela elangeni)

Ungcoliseko kunye nobushushu

Zonke iintambo ze-fiber optic ze-Dielectric Self Supporting (ADSS) zikwiindawo zombane eziphezulu. I-sheath yazo inokufakwa kwi-arcing eyomileyo kunye ne-corona ngakumbi kwiindawo ezingcolisekileyo kakhulu ezinemvula encinci apho kukho imvula ephezulu rhoqo kwintambo kwaye ayicocwa rhoqo ngamanzi emvula endalo. icocwe ngamanzi emvula endalo.

I-Corona okanye i-dry-band arcing igqobhoza i-cable sheath evumela ukungena kwamanzi okukhokelela ekutshatyalalisweni kwentambo ye-aramide kwaye iveze iityhubhu ze-PBT eziqulethe iifayibha ze-optical. Kwiimeko ezinzima ngakumbi ukuncipha okukhulu kwamandla oomatshini kunokukhokelela nasekuweni kweentambo.

Isiphumo seCorona

Ukukhutshwa kweCorona kulindeleke kwiindawo ezineendawo zombane eziphezulu ezibangelwa yimiphetho ebukhali, umzekelo, kwiincopho zeendibano zeentonga zesikrweqe zee-conductors zemigca yokudlulisa. Iindibano zeentonga zesikrweqe zinamathele kwizakhiwo zemigca yokudlulisa, iintambo zokuxhasa, zibonelela ngamandla oomatshini azikhusela ekugobeni kwaye zikwagaya iintambo. Ngokuxhomekeke ekubekweni kwentambo ngokubhekiselele kwii-conductors zevolthi ephezulu, ivolthi yomqhubi kunye nongcoliseko kumphezulu wekhebula kunokubangela ukuba umbane uhambe ecaleni kwentambo. Oku kubangela i-corona, i-micro-sparking kunye ne-dry band arcing, ingakumbi kufutshane nenqaba apho i-e-field inkulu khona. Iinkqubo zokukhutshwa kwenxalenye yendawo ziquka ukukhutshwa kwe-UV kunye nokudalwa kwe-ozone kunye nezinye ii-asidi, ii-reagents ezitshabalalisa ii-conductors zegalvanized kunye ne-ADSS sheath.

Ukubetha ngebhendi eyomileyo

Nangona iintambo ze-ADSS zingaqhubi ngombane, ungcoliseko oluqokeleleka kwisingxobo sazo sangaphandle lunokuziguqula zibe ziqhubi. Xa umaleko wongcoliseko umanzi ngokungalinganiyo uba yi-semi-conductor. Uninzi lweemeko ze-ADSS ezingasebenziyo zenzeka kwiindawo ezingcolisekileyo kakhulu okanye kwiindawo eziselunxwemeni. Umoya ovela elwandle uqhubela amathontsi amanzi anetyuwa kumphezulu wentambo ye-fiber-optic, ugqume intambo ngomaleko omncinci wetyuwa. Inkungu okanye umbethe umanzisa umaleko wongcoliseko kwaye wenze umaleko wongcoliseko kumphezulu wentambo. Ukudibanisa okunamandla phakathi kwabaqhubi besigaba kunye nentambo ye-fiber-optic kubangela umbane ecaleni komaleko wongcoliseko olumanzi. Lo mbane womisa umaleko kwaye wenze iibhendi ezincinci ezomileyo. Ibhendi eyomileyo iphazamisa umbane kwaye ivelise umbane ophezulu kulo lonke ibhendi. Le voltage ivelisa ii-arcs. Isiphumo sokufudumala se-arc sandisa ubude bebhendi eyomileyo, ethintela i-arcing. Nangona kunjalo, ukufuma kunye namanzi anetyuwa aqhutywa ngumoya avela elwandle amanzisa intambo kwaye aqalise kwakhona i-arcing. I-arcing yebhendi eyomileyo yinto eyenzeka rhoqo xa intambo imanzi kwaye ingcolisiwe ngaxeshanye.

Okukhona ungcoliseko kunye nokufuma kuphezulu, kokukhona umbane obangelwayo uphezulu, ngoko ke, kwiindawo ezingaphantsi kwetropiki, ukugoba kwebhanti eyomileyo kunye ne-corona ziyingozi kakhulu ngenxa yeemeko ezithile zemozulu: ixesha lokoma leenyanga ezisibhozo ukuya kwezisithoba lilandelwa lixesha elifutshane lemvula ebusika. Umaleko wongcoliseko lomphezulu wentambo emva kwexesha lokoma uqinile kwaye unamathela, kwaye utyebile ngakumbi kwiindawo ezikufutshane nee-clamps ezibangela ingxaki enkulu ye-corona.

Iinkampani ezisebenzela uluntu kufuneka zijonge iinkqubo zovavanyo lokuvavanya iintambo ze-ADSS fiber optic ezifakwe kwiintambo zombane eziphezulu. Imibutho efana ne-IEEE, i-WAPA, i-EPRI, i-BPA, iYunivesithi yaseWashington State kunye neminye iyaqhubeka nokufunda le ngxaki.
