Ukurikije IEC60228, imiyoboro ya kabili igabanijwemo ubwoko bune, ubwoko bwa mbere, ubwoko bwa kabiri, ubwoko bwa gatanu, nubwoko bwa gatandatu.Ubwoko bwa mbere nuyobora neza, ubwoko bwa kabiri ni umuyoboro uhagaze, ubwoko bwa mbere nubwa kabiri bugenewe gukoreshwa mu nsinga zashyizweho, ubwoko bwa gatanu nagatandatu bugenewe gukoreshwa mu nsinga zoroshye n’imigozi, naho iya kabiri ubwoko bugenewe abayobora insinga zoroshye.Itandatu iroroshye kuruta iya gatanu.
1. Umuyobozi ukomeye:
Icyuma cyumuringa cyometseho cyangwa kidashyizwe hamwe, insinga ya aluminiyumu cyangwa aluminiyumu yifashishije ibikoresho byuyobora.
Imiyoboro ikomeye y'umuringa igomba kuba izengurutse uruziga, 25mm2 no hejuru yumuringa ukomeye wumuringa ugenewe gusa insinga zidasanzwe, ntabwo ari insinga rusange;Kubatwara aluminiyumu ikomeye, igice cya 16mm2 no munsi yacyo kizenguruka, kuri 25mm2 no hejuru yacyo, kizenguruka mugihe cyinsinga imwe, kandi gishobora kuba kizunguruka cyangwa gikozwe mugihe cyinsinga nyinshi.
2. Umuyobozi uhagaze:
Kugirango wongere ubworoherane cyangwa kugororwa kwumugozi, insinga ya kabili hamwe nigice kinini cyambukiranya igizwe no guhinduranya insinga nyinshi imwe hamwe na diameter nto.Umugozi winsinga wagoretse ninsinga nyinshi imwe ifite imiterere ihindagurika kandi nini nini.Iyo insinga ya wire igoramye, ibice byimbere ninyuma byumurongo wo hagati wumurongo winsinga urashobora kwimuka no kwishyurana.Iyo yunamye, ntabwo bizatera guhindagurika kwa plastike yuyobora, bityo insinga ya wire iroroshye.Imikorere n'umutekano biratera imbere cyane.
Uburyo bwo gutondekanya intangiriro burashobora kugabanywamo ubwoko bubiri, guhuza bisanzwe no guhagarara bidasanzwe.Igisobanuro cyo guhora gisanzwe ni: guhuza abayobora hamwe nibisanzwe, kwibanda hamwe nibice bikurikirana mubyerekezo bitandukanye byitwa guhagarara bisanzwe.Irashobora kandi kugabanywamo ibice bisanzwe bisanzwe no guhagarara bidasanzwe.Iyanyuma yerekeza kumurongo-Kuri-Guhora umurongo hamwe na diameter zitandukanye, mugihe iyambere isobanura ko diametre yinsinga zigize zose ari zimwe;Guhora bisanzwe birashobora kandi kugabanywa muburyo bworoshye busanzwe hamwe no guhuza bisanzwe.Iyanyuma isobanura ko insinga zigize umurongo usanzwe zitari imwe, ahubwo zahinduwe mumigozi ninsinga zoroheje ukurikije amategeko, hanyuma zigahinduka mumutwe., ubu bwoko bwo kugoreka bukoreshwa cyane mukwimura intangiriro ya kabili ya reberi kugirango irusheho guhinduka.Guhagarikwa bidasanzwe (bundled), insinga zose zigizwe nu cyerekezo kimwe.
2.1 Abadafite uruziga rudahuzagurika:
Igice cyambukiranya umuzenguruko wa aluminiyumu muri rusange ntabwo kiri munsi ya 10mm2.Insinga imwe mu kiyobora igomba kuba ifite diameter imwe, kandi umubare winsinga imwe hamwe na DC birwanya umuyobozi bigomba kuba byujuje ubuziranenge.
2.2 Kwiyunvira kwizengurutse kuzenguruka hamwe nuyobora:
Igice cyambukiranya imiyoboro ya aluminiyumu izengurutse cyane ntigomba kuba munsi ya 16mm2, igice cyambukiranya umuringa cyangwa umuringa wa aluminiyumu cyahagaritswe ntigomba kuba munsi ya 25mm2, igipimo cya diameter cyinsinga ebyiri zitandukanye mumashanyarazi imwe ntigomba kurenza 2 , n'umubare w'insinga imwe hamwe na DC birwanya umuyobozi bigomba kuba byubahiriza amabwiriza asanzwe.
3. Umuyobozi woroshye:
Abayobora bagomba kuba bafite insinga z'umuringa zometseho kandi zidashyizwe hamwe.Intsinga imwe mu kiyobora igomba kuba ifite diameter imwe, diameter ya insinga imwe mu kiyobora ntigomba kurenza agaciro ntarengwa kagenwe, diameter ya kiyobora ya gatandatu iroroshye kurusha iy'umugozi wa gatanu uyobora umugozi umwe, hamwe nuyobora kurwanya ntibigomba kurenza agaciro ntarengwa kavuzwe mubisanzwe.
