Umzekelo, zinokuthumela idatha ngesantya esiphezulu ngelixa zisebenza njengendlela ekhuselekileyo yokumisa umbane okanye umbane. Ezinye zeentambo ezintsha ze-hybrid zisebenzisa nezinto ezingezizo zesinyithi ukuphelisa ukuphazamiseka kwe-electromagnetic ngokupheleleyo. Oku kunceda ukugcina imiqondiso ecocekileyo kwaye kuthintela izixhobo ezongezelelweyo ekubeni zingafumani i-static, nto leyo ezenza zibe lukhetho oluhle kwiindawo ezinoxinzelelo olukhulu lwamaza erediyo okanye imigca yamandla e-voltage ephezulu.

Uzinzo luya luba yinto ephambili kwishishini leenkonzo zombane. Izinto ezintsha zeentambo azigcini nje ngokwandisa ubomi bazo—ezinye ukuya kuthi ga kwiminyaka engama-40—kodwa zilula nokuzifaka, nto leyo enokunciphisa iindleko zomsebenzi ngama-30 ukuya kuma-40 ekhulwini. Ixesha elincinci emsebenzini lithetha ukunciphisa umngcipheko kubasebenzi kunye nokunciphisa ixesha lokungasebenzi kwabasebenzisi beentambo. Ukusebenzisa izinyithi ezimbalwa kunye nezinto ezisetyenzisiweyo kwakhona kuluncedo kwiplanethi kwaye kunokunciphisa iindleko ekuhambeni kwexesha. Ezinye zeentambo zethu ezintsha zenzelwe nokuba ziphinde zisetyenziswe lula xa zifikelela esiphelweni somjikelo wazo wobomi.

Zonke ezi nguqu zibeka i-fiber kwindawo yokuba ibe yinxalenye ebalaseleyo yenethiwekhi zexesha elizayo, zombini zonxibelelwano kunye nokuhanjiswa kombane. Ngeentambo eziqinileyo, ezinobunzima beentsiba, nezikrelekrele, iinethiwekhi zinokufikelela phambili kwaye zisebenze ngempumelelo ngakumbi, zixhasa uluntu lwasezidolophini nolwasemaphandleni ngokufanayo ukuba lufakwe.

Isiphelo

I-ADSS vs OPGW akufuneki ibe yingxaki. Zombini iintambo zenza imisebenzi ebalulekileyo kwiigridi zamandla. I-ADSS ikhanya ngakumbi kwiindlela ezixineneyo kakhulu. I-OPGW ifanelana kakuhle neentambo ze-high-voltage. Intambo nganye inexabiso layo, ukusuka kwisantya sokusasazwa kwayo ukuya kwiimfuno zayo zokugcinwa. Uninzi lwamaqela lujonga imigaqo yokhuseleko, iindleko, kunye nokungxamiseka. Iigridi ezikrelekrele kunye nobuchwepheshe obutsha ziyaqhubeka nokuqhubela phambili zombini ezi ngxaki. Ebaleni, amaqela afumana iingenelo ezibonakalayo ngokwenza ukhetho oluchanekileyo. Amaqela alinganisela iimfuno, uyilo lwendawo, kunye neenjongo zexesha elizayo zikhetho ezilungileyo. Jonga kakuhle iinjongo zakho zegridi kunye neemfuno zasekuhlaleni, uze udibane nengcali yekhebula ukuze ufumane isisombululo esifanelekileyo.

Imibuzo ebuzwa qho

Yintoni umahluko omkhulu phakathi kweentambo ze-ADSS kunye ne-OPGW?

Iintambo ze-ADSS (All-Dielectric Self-Supporting) azinazo isinyithi kwaye azikwazi ukukhupha umbane, nto leyo eyenza ukuba zilungele imigca yokudlulisa umbane ophezulu, ngelixa iintambo ze-OPGW (Optical Ground Wire) zidibanisa i-fiber optics kunye ne-grounding ukuze kuphuculwe ukusebenza kwe-optical kunye nonxibelelwano.

Yeyiphi intambo elula ukuyifaka, i-ADSS okanye i-OPGW?

Iintambo ze-ADSS, ezaziwa ngokuba luncedo ekusebenzeni kakuhle kwe-optical, zihlala zilula kwaye zikhawuleza ukuzisebenzisa, zivumela ukufakwa kwi-live-line ngaphandle kokucima kombane.

I-ADSS kunye ne-OPGW zisebenza njani kwiindawo ezinzima?

Intambo ye-ADSS fiber optic ayichaphazeleki kukuphazamiseka kwe-electromagnetic kodwa inokuba semngciphekweni womoya nomkhenkce, ngelixa iintlobo zeentambo ze-OPGW ziyakwazi ukumelana nemozulu embi kwaye zifuna umhlaba ofanelekileyo ukuqinisekisa ukhuseleko.

Yeyiphi intambo engabizi kakhulu xa idluliselwa kumgama omde?

Iintambo ze-ADSS zidla ngokuba zingabizi kakhulu xa zinobude obuphakathi kunye nokulungiswa kwakhona, ngelixa iintlobo zeentambo ze-OPGW zinokuba zezona zilungileyo kwizakhiwo ezintsha ezifuna zombini unxibelelwano lwe-fiber optic kunye nocingo oluphantsi komhlaba.

Zeziphi iindima ezidlalwa zezi ntambo ekuphuculeni iigridi zamandla?

Zombini iintlobo zeentambo ze-ADSS kunye ne-OPGW zivumela unxibelelwano lwedatha oluthembekileyo, luphucula ukhuseleko lwegridi kwaye luvumela amandla egridi ekrelekrele kwiinkqubo zokuhambisa umbane.

Ngaba kukho naziphi na izinto ezintsha ezizayo kwiintambo ze-ADSS kunye ne-OPGW?

Ukujonga phambili, izinto ezintsha kwiziko lonxibelelwano lwefayibha ye-optical ezijikeleze ukwanda koxinano lwefayibha, izixhobo ezintsha zokomeleza amandla kwiintlobo zeentambo ze-opgw, kunye neendlela zokusasazwa ezilungiselelweyo ukuphucula ukusebenza kakuhle kunye namaxabiso aphantsi.

Ngaba iintambo ze-ADSS kunye ne-OPGW zingasetyenziswa kunye?

Ewe, iinkonzo zombane ngamanye amaxesha zisebenzisa zombini iintambo ze-ADSS kwiindawo ezingenasidingo sokufaka isiseko kunye neentambo ze-OPGW kwiindawo ezifuna isiseko kunye nonxibelelwano!
