Ubungakanani begeyiji yocingo bubhekisa ekulinganisweni kobubanzi bentambo. Le yinto ebalulekileyo ekufuneka iqwalaselwe xa ukhetha ucingo olufanelekileyo kwisicelo esithile. Ubungakanani begeyiji yocingo budla ngokumelwa linani. Okukhona inani lincinci, kokukhona ububanzi bentambo bukhulu. Okukhona inani likhulu, kokukhona ububanzi bentambo buncinci. Ukuze uqonde ubungakanani begeyiji yocingo ngokulandelelana, kubalulekile ukuba nolwazi olusisiseko ngenkqubo yegeyiji yocingo.
Inkqubo yokulinganisa intambo yindlela eqhelekileyo yokulinganisa ububanzi bentambo kwaye isetyenziswa kakhulu eMelika. Eyona ndlela isetyenziswa kakhulu yokulinganisa ubukhulu bentambo yinkqubo ye-American Wire Gauge (AWG). Kwiinkqubo ze-AWG, ubungakanani bentambo yokulinganisa buqala kwi-0000 (4/0) ukuya kwi-40, apho i-0000 yeyona ntambo iphezulu kwaye i-40 yeyona ntambo incinci.
Itheyibhile 1: itshathi yokulinganisa ucingo
Kwicandelo le-metrology, oko kukuthi, uphando lwesayensi lokulinganisa, iigeyiji zentambo zisetyenziselwa ukulinganisa ububanzi okanye indawo enqamlezileyo yeentambo ezingqukuva, eziqinileyo, ezingenayo i-ferrous, eziqhuba umbane. Ngokusebenzisa ububanzi okanye indawo enqamlezileyo yentambo, iigeyiji zentambo zinceda abasebenzisi ekwazini amandla okuthwala umbane eentambo eziqhuba umbane.
Ubungakanani begeyiji yentambo abubonisi nje kuphela ukuba ingakanani i-current enokudluliselwa okanye idluliselwe ngokukhuselekileyo kwintambo, kodwa nokumelana kwentambo kunye nobunzima bayo ngeyunithi nganye yobude, nako. Igeyiji yentambo ikwabonisa ubukhulu be-conductor ezidlula kuyo ii-electron. Ukuze kudluliselwe kakuhle, i-conductor yentambo kufuneka yonyuswe ukuze kuncitshiswe ukumelana.
Ukuqonda ubungakanani beegeyiji zentambo ngokulandelelana kubalulekile kwiintlobo ngeentlobo zezicelo ezinje ngentambo yombane, intambo yeemoto, njl. Ukukhetha ubungakanani obuchanekileyo beegeyiji zentambo kubalulekile ekuqinisekiseni ukuba intambo iyakwazi ukuthwala umbane ofunekayo ngokukhuselekileyo ngaphandle kokutshisa kakhulu okanye ukubangela ukwehla kwevolthi.
