Ibyuma birwanya ibyumamubisanzwe bigizwe na résistoriste, insulator, abasimbuka imbere, hamwe na barwanya abaministri.
Kurwanya ibyuma birwanya ibyuma bidafite ingese bikozwe mubintu bidasanzwe byuma bya karubone, bifite coeffisente ntoya yubushyuhe hamwe nimpinduka ntoya yo kurwanya mugihe ikora. Kuri gahunda imwe yo gushushanya, gahunda yo gutunganya ibice bya bolt imbaraga zubutaka mubyuma bidafite ibyuma bitanga umurongo woroshye, kugaragara neza, no kugenzura byoroshye ugereranije no gusudira amashanyarazi gakondo.
Ibigize insulasiyo, nkibiri hagati yimigozi irwanya imitwe, bikozwe mubikoresho birwanya ubushyuhe bwinshi.
Ibyuma bitarwanya ibyuma bifite ibintu bitanu byingenzi:
1) Bakoresha tekinoroji igezweho yitwa "electrode" ihuza, isimbuza uburyo gakondo bwo guhuza. Igikorwa cyo gusudira cyemeza guhuza gukomeye hamwe nubuso bwiza bwo gusudira byibuze 80m.
2) Birakwiriye muburyo butandukanye bwo gusaba, harimo AC 50Hz, 1000V voltage, na DC itanga amashanyarazi.
3) Zirwanya ruswa mubushuhe bwo hejuru hamwe nubushuhe buhebuje kubera kubura ibintu byangirika.
4) Ikintu kirwanya ibyuma kidafite ingese kashe yashyizweho kashe hifashishijwe ibikoresho byihariye, bituma habaho indangagaciro zitandukanye zo kurwanya. Muguhitamo ibyuma bitagira umwanda, kurwanya birashobora kwiyongera hafi 20%, bikavamo kuzigama amafaranga no kugabanuka kwamashanyarazi ugereranije nagasanduku gakondo. Byongeye kandi, ntabwo hakenewe induction, biganisha ku kuzigama ingufu zingana na 35%.
5. Igishushanyo gikuraho amashanyarazi yumuriro, bigabanya cyane gutakaza ingufu.
