15kVA 13.8kV hal-waji hal-weji ah oo tiirka ku rakiban yahay is beddelka qaybinta cufan, fudfudud si madax-bannaan u habeeyay oo ay u samaysay Yawei, si gaar ah loogu farsameeyay nidaamyada qaybinta awoodda sare. Loogu talagaly in uu la kulmo xaaladaha saadka tamarta hoose ee Waqooyiga Ameerika iyo magaalooyinka, Transformer-kan hal-waji ah waxa uu ku shaqeeyaa inta jeer ee nidaamka 60Hz, isaga oo si buuxda u raacaya ANSI/IEEE C57.12.00, heerarka hufnaanta DOE iyo tilmaamo kale oo caalami ah. Soo bandhigista rakibaadda tiirarka, qaab-dhismeedka fudud, waxqabadka la isku halayn karo iyo kharashyada dayactirka hawlgalka oo hooseeya, waxay ku habboon tahay qaybinta awoodda baahsanaanta, sahayda korantada deegaanka, tas-hiilaadka ganacsiga yar yar iyo mashaariicda sahayda tamarta fog, bixinta beddelka korantada xasilloon oo badbaado leh iyo gudbinta korantada ee korantada awoodda hoose.
