Aluminium Kurwanyana Cement Resistors bari mubyiciro bimwe birwanya wirewound, ariko nta tandukaniro riri hagati ya Aluminium Resistors na Cement Resistors kubijyanye nagaciro ko guhangana. Kurwanya sima ni birwanya wirewound bifunze hamwe na sima, ni ukuvuga, insinga ya résistoriste ikomeretsa ku bice bya ceramic bitarwanya alkaline, hanze yacyo hiyongeraho ubushyuhe-, ubushuhe-, hamwe n’ibikoresho birwanya ruswa kugirango birinde kandi bikosorwe, kandi umubiri wurwanya wa wirewound ushyirwa mumurongo wa ceramic kare, wuzuye kandi ugafungwa hamwe na sima idasanzwe idashobora gukongoka. Uruhande rwinyuma rwa sima rurwanya rugizwe ahanini nubutaka. Hariho ubwoko bubiri bwa feri ya sima irwanya: sima isanzwe irwanya sima hamwe na talc farfor ya sima irwanya.
Uhereye kububasha bwo kureba, imbaraga zaaluminium yubatsweirashobora gukorwa nini, ariko irwanya sima irashobora gukorwa gusa 100W. Aluminiyumu yubatswe irwanya imbaraga zo hejuru, zishobora kwemerera kunyura mumigezi minini. Uruhare rwarwo ni kimwe na résistoriste rusange, usibye ko rushobora gukoreshwa mugihe cyumuyaga mwinshi, nko murukurikirane hamwe na moteri kugirango ugabanye umuvuduko wa moteri, agaciro kokurwanya muri rusange ntabwo ari nini. Kurwanya sima bifite ibiranga ubunini buto, kurwanya ihungabana, kurwanya ubushuhe, kurwanya ubushyuhe no gukwirakwiza ubushyuhe bwiza, igiciro gito, nibindi bikoreshwa cyane mumashanyarazi, ibikoresho byamajwi, amajwi, ibikoresho, metero, televiziyo, imodoka nibindi ibikoresho.
Uhereye kubireba ubushyuhe bwo gukwirakwiza imikorere, kugirango ugereranye byoroshye,aluminiyumu yarimo abarwanyabihwanye no guhumeka, kandi birwanya sima bihwanye nabafana. Aluminium shell yubushyuhe bukora nibyiza, kurenza urugero birashobora gukonjeshwa mugihe, kugirango ubushyuhe bwo guhangana butagera hejuru cyane, murwego runaka, agaciro kokurwanya ntigahinduka, mugihe sima irwanya ubukonje kugirango ibe mbi cyane. Mugihe cyo kubyaza umusaruro, aluminiyumu yubatswe irwanya kandi ifite ibikoresho bya sima imbere, itandukaniro nuko imwe hanze yipaki ari aluminiyumu, imwe hanze ni farufari.
