Nidaamka daloolista dahaarka: Xirmooyinka madaxa-xiiradu waxa ay hubisaa xakamaynta saxda ah ee xidhidhiyeyaasha dahaarka ee ABC.Rakibadu waa nadiif waana sahlan tahay sababtoo ah qty aad u hooseeya oo dufan ah ayaa looga baahan yahay biyo la'aanta xirayaashan dahaaran.Xidhiidhiyayaasha IPC-da ee kore waxa lagu tijaabiyay "ay u adkaysanayaan 6kV biyaha" marka loo eego heerka NFC 33-020.

Xidhiidhiyaha Dulitaanka Dahaaran (IPC) ayaa si weyn loogu isticmaalaa Khadadka Korantada Hoose ee Hawada Sare (LV ABC) ilaa 1KV iyo sidoo kale isku xirka nidaamka khadka adeegga, nidaamka qaybinta qoyska, nidaamka qaybinta qaab-dhismeedka ganacsiga, nidaamka qaybinta iftiinka waddooyinka iyo nidaamka isku xirka dhulka hoostiisa .

Daabadaha isku xidhayaasha dahaarka ayaa ka samaysan naxaas qasacadaysan ama naxaas dahaadhaysan ama daawaha aluminium oo u oggolaanaya isku xidhka dabaylaha Al ama Cu.

Ku qalabaysan hal ama laba jibbaaran oo madaxa xiiran.Nuska kontoroolka torque-ga ayaa isku sawiraya labada qaybood ee xidhiidhiyaha oo uu xiiro marka ay ilkuhu ka daloolaan dahaarka oo ay la xidhiidhaan xadhigga kirishbooyada.
