I-wire pre-stranded isetyenziselwa ukudibanisa izixhobo ze-conductor yamandla aphezulu kunye ne-terminal terminal cable, ukumiswa kunye nokudibanisa. Ucingo olufakwe ngaphambili lwavela okokuqala eMelika ngeminyaka yoo-1940 kunye no-1950. Imveliso yoqobo yayilukhuselo locingo olujikelezayo lwendawo yoxinzelelo yocingo olungenanto kunye nesikhundla sokutya kombane kunye nokutsha kwe-arc. Emva kweminyaka yophuhliso, izixhobo zocingo ezijijelweyo zisetyenziswe ngokubanzi ekuhanjisweni nasekusasazeni amandla, unxibelelwano lwefiber optical, umzila kaloliwe wombane, i-cable TV, ulwakhiwo, ezolimo kunye nezinye iindawo.
I-steel core aluminium wire isetyenziswa ngokubanzi kuthungelwano losasazo lwe-kV ye-10 kV yocingo oluqhelekileyo, inoluhlu lweenzuzo zamandla aphezulu, ukusebenza kakuhle kombane wokukhusela, ixabiso eliphantsi, lisetyenziswa ngokubanzi kwiidolophu zoqhagamshelwano lwasezidolophini kunye nemigca yamandla asemaphandleni. . Nangona kunjalo, xa umgca wentsimbi ye-aluminium conductor core wonakaliswa ngamandla angaphandle okanye isimo sezulu esibi, kulula ukuba nephutha lesiphaluka esifutshane. Xa isekethe emfutshane edibeneyo isenzeka, ucingo luya kwaphulwa. Xa imeko enjalo ifunyenwe, unyango olufanelekileyo lokulungisa ucingo kufuneka lunikezwe ngexesha lokuphepha ukuqhubeka kweentambo ezikhululekile ezikhokelela ekunciphiseni iimpawu zomatshini kunye nombane wocingo.
I-Prestranded wire yimveliso yenani le-single-strand spiral wire prestranded. Ngokomlinganiselo wecandelo lomnqamlezo wocingo, i-helix wire ene-diameter yangaphakathi echaziweyo ijikeleziswa ecaleni kwendlela ye-helix ukwenza i-tubular cavity. Ucingo olufakwe ngaphambili luthandelwe luthandelwe kumaleko angaphandle ocingo. Ngaphantsi kwesenzo sokunyanzeliswa kocingo, i-spiral ijikeleza ukwenza i-anchorage force yocingo. Okukhona utsalo lwecingo lusiba lukhulu, kokukhona i-spiral iqina kwaye kokukhona amandla okubambelela esanda. Intambo yangaphambili yokulungisa i-prestranded isetyenziswe ngokubanzi kwi-35 kV kunye nemigca engaphezulu, kodwa ingaphantsi kwimizila ye-kV ye-10, kwaye ingasetyenziselwa kuphela kwicandelo lomgca kunye ne-7% okanye i-strand ephantsi ephukile kwaye uluhlu lomonakalo alukhulu, kwaye ayikwazi ukufikelela kwisiphumo sokuqinisa. Uxinzelelo lwangaphambili lwebar yokudibanisa luhlobo olutsha lweemveliso zocingo olujikwe ngaphambili kwiminyaka yakutshanje. Isetyenziswa njengoluhlobo lwesixhobo sokudibanisa. Ingasetyenziselwa ukubuyisela umbhobho odibeneyo woxinzelelo oluqhelekileyo kunye nombhobho woxinzelelo, ingasetyenziselwa ukudibanisa i-aluminium stranded wire, i-aluminium alloy wire stranded, i-steel core aluminiyam i-wire stranded kunye nezinye iingcingo, ukufezekisa amandla ayo okuqala omatshini kunye nokusebenza kombane.
