Imashini yo gufunga imizigo ifite imyanya ibiri ikoreshwa cyane cyane mu guhindura agasanduku k’Abanyamerika ko mu bwoko bwa terminal, hamwe n’uburyo bwo gukora mu mpeshyi, ni imashini yo guhuza imizigo ifite ibyiciro bitatu kugira ngo irangize igikorwa cyo gufunga no kugabanya imizigo.
Binyuze muri ubwo buryo bubiri bwo gusimbuza imizigo bushobora kandi kuba bugizwe na sisitemu yo gusimbuza imizigo yo mu bwoko bwa ring kuri sisitemu yo gukwirakwiza imizigo yo mu bwoko bwa ring, aho gusimbuza imizigo yo mu buryo bubiri bihagaze: kurika no kuzimya. Igipimo cya 10kV gishobora gukoreshwa mu mishinga y'ingufu z'umuyaga mu gukoresha transfoma.
Mbere yo gukoresha transformateur, igomba kuyumisha.
Huza amahame ya JB/T10681-2006, ikoreshwa ry'amabwiriza ajyanye n'amabwiriza ya GB10230.
Ibisobanuro:
| Ibisobanuro | Ibipimo |
| (kV) Voltage ihoraho ikora | 6 | 10 | 20 | 35 |
| (kV) Ibikoresho bifite voltage nyinshi kurusha ibindi | 7.2 | 12 | 24 | 40.5 |
| (kV)BIL na Grest yuzuye | 60 | 75 | 125 | 200 |
| (A) Umuvuduko w'amazina uhoraho | 200 | 315 | 400 | 630 |
