Urusobe ni umuyoboro uhuza amashanyarazi y’amashanyarazi n’umurongo wa voltage mwinshi utwara amashanyarazi mu ntera imwe kugeza kuri sitasiyo - “guhererekanya”.Iyo icyerekezo kigeze, insimburangingo zigabanya voltage yo "gukwirakwiza" kumurongo wa voltage yo hagati hanyuma ukagera kumurongo muto wa voltage.Hanyuma, transformateur kuri pole ya terefone irayigabanya kuri voltage yo murugo ya volt 120.Reba igishushanyo gikurikira.

Imiyoboro rusange irashobora gutekerezwa nkigizwe nibice bitatu byingenzi: ibisekuruza (ibimera no kuzamura intambwe), guhererekanya (imirongo na transformateur ikora hejuru ya 100.000 volt - 100kv) no gukwirakwiza (imirongo na transformateur munsi ya 100kv).Imiyoboro yohereza ikora kuri voltage ndende cyane 138.000 volt (138kv) kugeza kuri 765.000 volt (765kv).Imirongo yohereza irashobora kuba ndende - kuruhande rwa leta ndetse no kumurongo wigihugu.

Kumirongo miremire, ikoreshwa neza cyane voltage ikoreshwa.Kurugero, niba voltage ikubye kabiri, ikigezweho cyaciwemo kabiri kubwingufu zingana.Igihombo cyohereza umurongo kiringaniye na kare ya none, umurongo muremure "igihombo" ugabanywa nibintu bine niba voltage ikubye kabiri.Imirongo "Gukwirakwiza" iba hafi mumijyi no mu turere tuyikikije kandi igafana hanze muburyo busa nigiti.Iki giti kimeze nkimiterere gikura hanze kiva mumasimburangingo, ariko kubwintego yo kwizerwa, mubisanzwe kirimo byibuze byibuze kimwe kidakoreshwa cyinyuma kidasubirwaho hafi yacyo.Ihuza rirashobora gushobozwa byihuse mugihe byihutirwa kugirango agace ka podiyumu gashobora kugaburirwa nubundi buryo.
