Ngokusekelwe ekusetshenzisweni kwazo okuhlosiwe, izintambo zikagesi zingahlukaniswa zibe izinhlobo ezihlukahlukene, okuhlanganisa izintambo zokudlulisela, izintambo zokulawula, izintambo zokuxhumana, izintambo zezinsimbi, nezintambo ezibonakalayo. Ngokusekelwe kwisakhiwo sazo, zingaphinda zihlukaniswe zibe izintambo eziphezulu kanye nezintambo ezingaphansi komhlaba. Ngaphezu kwalokho, izintambo zikagesi zingahlukaniswa ngokusekelwe ezintweni ezihlukahlukene, njengempahla ye-conductor, i-sheathing material, kanye nezinga le-voltage.
Izintambo zikagesi ngezinjongo ezihlukene zinezici ezihlukile nezindawo zokusebenzisa. Isibonelo, amakhebuli okudlulisela asetshenziselwa ngokuyinhloko{1}}ukudlulisa amandla kagesi kanye{2}phezulu{2}phezulu, ngokuvamile kumazinga aphezulu kagesi. Izintambo zokulawula, nokho, zinikeza izinzuzo ezinjengokuvikelwa kokuphazamiseka kwe-electromagnetic kanye nokudlulisa okuthembekile, futhi asetshenziswa ngokuyinhloko ezinhlelweni zokulawula ezizenzakalelayo nezokuqapha. Uma usebenzisa izintambo zikagesi, kubalulekile ukukhetha uhlobo lwekhebula olufanele kanye nokucaciswa okusekelwe kuhlelo lwazo oluthile.
