Ikhebula le-ADSS ifakiwe ngamafidi ayi-10 kuya kwangama-20 (3m kuya kwangama-6m) ngaphansi kwama-phase conductors. Izinsimbi ze-armor rod ezisekelwe phansi zisekela ikhebula le-fiber-optic esakhiweni ngasinye esisekelayo. Izinsiza zibike ukwehluleka kwe-ADSS efakwe emigqeni yazo ephezulu yamandla kagesi. Insimu kagesi ephezulu emigqeni yokudlulisela ikhiqiza ukukhishwa kwe-corona okuqhubekayo ekugcineni kwezinduku ze-armor ezisekelayo. Lokhu kukhishwa kuholela ekuwohlokeni kwekhebula. Ezindaweni ezingcolile, ukugoba kwebhande elomile kubangela ukonakala kwekhebula lapho inkungu noma amazolo kumanzisa ikhebula ngezinye izikhathi. Isikhathi sokuphila se-ADSS emigqeni yamandla sincike kulezi zinto ezilandelayo:

Ugesi

Umphumela we-Corona

Ukubopha ngebhande elomile

Umphumela ongaba khona wesikhala

Okwemishini

Ubude be-span kanye nokuwa

Ukucindezeleka kwezintambo

Ezemvelo

Ijubane lomoya kanye nokudlidliza kwe-Aeolian

Ukwakheka kwe-sheath kokumelana ne-UV (i-UV evela elangeni)

Ukungcola kanye nezinga lokushisa

Zonke izintambo ze-fiber optic ze-Dielectric Self Supporting (ADSS) zitholakala ezindaweni zikagesi eziphakeme. Igobolondo lazo lingafakwa ku-arcing yebhande elomile kanye ne-corona ikakhulukazi ezindaweni ezingcolile kakhulu ezinemvula encane lapho kunemvula eningi njalo edlula khona ikhebula futhi alihlanzwa ngamanzi emvula emvelo. Lihlanzwa ngamanzi emvula emvelo.

I-Corona noma i-dry-band arcing ibhoboza i-cable sheath evumela ukungena kwamanzi okuholela ekubhujisweni kwentambo ye-aramide futhi iveze amashubhu e-PBT aqukethe imicu ye-optical. Ezimweni ezimbi kakhulu ukwehla okukhulu kwamandla omshini kungaholela nasekuweni kwekhebula.

Umphumela weCorona

Ukukhishwa kwe-corona kulindeleke ezindaweni ezinezinkundla zikagesi eziphakeme zendawo ezibangelwa imiphetho ebukhali, isibonelo, eziqongweni zezinhlangano ze-armor-rod zabaqhubi bemigqa yokudlulisela. Izinhlangano ze-armor rod zinamathele ezakhiweni zemigqa yokudlulisela, izintambo ezisekelayo, zinikeza amandla okusebenza ezivikela ekugobeni futhi zigaye izintambo. Kuye ngokubekwa kwekhebula maqondana nabaqhubi be-voltage ephezulu, i-voltage yomqhubi kanye nokungcola ebusweni bekhebula kungabangela ukuthi ugesi ugeleze ngekhebula. Lokhu kubangela i-corona, i-micro-sparking kanye ne-dry band arcing, ikakhulukazi eduze kombhoshongo lapho i-e-field inkulu khona. Izinqubo zokukhishwa kwengxenye yendawo zihilela ukukhishwa kwe-UV kanye nokudalwa kwe-ozone namanye ama-acid, ama-reagents aguguza ama-galvanized conductor kanye ne-ADSS sheath.

Ukubopha ngebhendi eyomile

Ngisho noma izintambo ze-ADSS zingahambisi ugesi, ukungcola okuqongelela emgodleni wazo wangaphandle kungaziguqula zibe yizihambisi. Lapho ungqimba lokungcola lumanzi ngokungalingani, luba yizihambisi-moya. Amacala amaningi e-ADSS ehlulekayo enzeka ezindaweni ezingcoliswe kakhulu noma ezindaweni ezisogwini. Umoya ovela olwandle ushayela amaconsi amanzi anosawoti ebusweni bekhebula le-fiber-optic, umboze ikhebula ngengqimba encane kasawoti. Inkungu noma amazolo kumanzisa ungqimba lokungcola futhi kwakha ungqimba oluhambisa ugesi ebusweni bekhebula. Ukuhlangana okunamandla phakathi kwabaqhubi besigaba nekhebula le-fiber-optic kubangela ugesi eduze kwengqimba yokungcola emanzi. Lo gesi womisa ungqimba futhi kwakha amabhande amancane omile. Ibhande elomile liphazamisa ugesi futhi likhiqize i-voltage ephezulu kulo lonke ibhande. Leli voltage likhiqiza ama-arcs. Umphumela wokushisa we-arc wandisa ubude bebhande elomile, okuvimba i-arcing. Kodwa-ke, ukuminyana kanye namanzi anosawoti aqhutshwa ngumoya avela olwandle kumanzisa ikhebula futhi kuphinde kuqalise i-arcing. I-arcing yebhande elomile yinto eyenzeka njalo lapho ikhebula limanzi futhi lingcolile ngasikhathi sinye.

Uma ukungcola nomswakama kuphakeme, kulapho ugesi obangelwayo uphakama khona, ngakho-ke, ezindaweni ezingaphansi kwezindawo ezishisayo, ukugoba kwebhande elomile kanye ne-corona kuyingozi kakhulu ngenxa yezimo zezulu ezithile: isikhathi sokoma sezinyanga eziyisishiyagalombili kuya kweziyisishiyagalolunye kulandelwe isikhathi esifushane semvula ebusika. Ungqimba lokungcoliswa kobuso bekhebula ngemva kwesikhathi sokoma luqinile futhi lunamathela, futhi lujiyile kakhulu ezindaweni eziseduze nama-clamp okubangela inkinga enkulu ye-corona.

Izikhungo kufanele zibheke izinqubo zokuhlola ukuhlola izintambo ze-ADSS fiber optic ezifakwe ezintanjeni zikagesi eziphezulu. Izinhlangano ezifana ne-IEEE, i-WAPA, i-EPRI, i-BPA, i-Washington State University nezinye ziyaqhubeka nokufunda lolu daba.
