KUTHENI IICABLES ZOMOYA ZINEEYILE EZININZI?

Iintambo zombane ziintambo eziqhelekileyo zokusasaza nokudlulisa amandla ombane. Zihlala zisetyenziswa kwiigridi zombane ezingaphantsi komhlaba ezidolophini, umbane wangaphakathi kumashishini emizi-mveliso kunye nemigodi, njalo njalo. Abantu abanolwazi oluthile ngeentambo baya kufumanisa ukuba iintambo zombane zineeleya ezininzi, kutheni ke iintambo zombane zineeleya ezininzi kangaka?

Umaleko ongaphandle wentambo yamandla esinokuwubona ngokubonakalayo udla ngokuba wenziwe ngerabha okanye irabha eyenziwe ngesleeve, engapheleli nje ekugqumeni ubushushu, kodwa ikwakhusela intambo kumonakalo wangaphandle. Iintambo zamandla zinokwahlulwa zibe ziintambo ze-voltage ephezulu kunye neentambo ze-voltage ephantsi ngokwenqanaba le-voltage. Iintambo ze-voltage ephezulu ziqulathe umaleko we-insulation, ofana kakhulu ne-resin fillers, ngelixa iintambo ze-voltage ephantsi zingenalo olu maleko. Ukuze kuzaliswe izikhewu ngaphakathi kwentambo yamandla, into efana neribhoni kufuneka isongwe kumbindi ngamnye.

Indima yomaleko wokukhusela wentambo yombane yahlulwe kwiimeko ezimbini. Ngenxa yombane omkhulu odlula kwintambo yombane, kuya kuveliswa intsimi yemagnethi ejikeleze umbane. Ukuze kuthintelwe ezinye izinto ekuchaphazelekeni ngumbane, kongezwa umaleko wokukhusela kwintambo. Ukongeza, imeko yesibini kukuba ukuba umongo wentambo wonakele, umbane uyaphuma kwaye ugeleze ungene kwinethiwekhi yokumisa umhlaba ecaleni komaleko wokukhusela, odlala inqanaba elithile lokhuseleko lokumisa umhlaba.

Izinto eziqhelekileyo kwiintambo zombane zii-cores eziqhuba umbane, iileya zokuthintela ubushushu, kunye neeleya zokukhusela. Ngokweenkcukacha, inokwahlulwa ibe yi-conductive wire core, i-inner semiconducting layer, i-insulating layer, i-outer semiconducting layer, i-copper shielding, i-filler, i-inner lining layer, i-steel tape protective layer, kunye ne-outer protective layer.
