Isithinteli sefuse esiphumayo kunye nesithinteli sefuse esitshintsha umthwalo zizixhobo zokukhusela zangaphandle ezine-voltage ephezulu. Ziqhagamshelwe kwi-feeder engenayo yokusasaza, i-transformer okanye imigca yokusasaza. Ikhusela ikakhulu i-transformer okanye imigca kwi-short circuit kunye nomthwalo wokulayisha we-ON/OFF. Isithinteli sefuse esiphumayo senziwe zi-insulator supports kunye ne-fuse tube. Izithinteli eziqinileyo ziqiniswe kumacala amabini enkxaso ye-insulator, izithinteli ezihambayo zifakelwe kwiziphelo zokutsala ze-fuse tube. I-fuse tube yenziwe yi-arc extinguishing tube yangaphakathi. I-Outlineer phenolic compound paper tube okanye i-epoxyglasstube. Isithinteli sefuse esitshintsha umthwalo sinika izithinteli ezincedisayo ze-elastic kunye nesikhuselo se-arc sokutshintsha i-on-off loading current. Kwimeko yokusebenza eqhelekileyo, i-fuse link iqinisiwe, i-fuse tube iqinisiwe ukuze isondele. Kwimeko apho inkqubo iphosakele, i-fault current iya kuvumela i-fuse inyibilike ngoko nangoko kwaye i-arc yombane iya kuziswa, evumela i-arc extinguishing tube ukuba ifudumale kwaye isombulule igesi eninzi. Oku kuya kuvelisa uxinzelelo oluphezulu kwi-tub, kwaye ivuthuze kunye ne-tube, kwaye emva koko i-arc iya kwandiswa kwaye icime. Emva kokuba ikhonkco le-fuse linyibilikile, oonxibelelwano abashukumayo abanawo amandla aqinileyo, isixhobo sokutshixa siyayikhulula i-fuse, ityhubhu ye-fuse iyawa, ukusika ngoku kukwindawo evulekileyo. Xa kufuneka icime ngexesha lokulayisha ukusika, sebenzisa ibhola yokusebenza yokukhusela ukutsala unxibelelwano olushukumayo, ngoku unxibelelwano oluphambili kunye noonxibelelwano oluxhasayo oluzinzileyo lusanxibelelana. Ngelixa betsala, oonxibelelwano abancedisayo bayahlulwa, kwaye emva koko i-arc yombane yenzeka phakathi koonxibelelwano abancedisayo, i-arc yolulwa kwi-arc shield, kwangaxeshanye i-arc shield iqhuma igesi, xa ubuninzi bombane bugqithiswa, buyivumele icime.
