Mamita amphamvu kwambiri amayikidwa m'bokosi, popanda mita ya ola la watt, yotchedwa transformer yophatikizika, ndi mtundu wakunja womizidwa ndi mafuta a AC (oyeneranso m'nyumba).Ndi chipangizo choyezera mwachindunji mphamvu yogwira ntchito ndi yotakasuka mumizere yothamanga kwambiri.Yogwiritsidwa ntchito pazigawo zitatu za AC ndi mafupipafupi ovotera 50, 60Hz;10KV, 6KV, 3KV dongosolo network.Ili ndi ubwino wa kulondola kwakukulu, kukonzanso kuwala, kukhazikitsa kosavuta komanso kutsutsa kuba kwa magetsi.Ndi ambiri m'madipatimenti magetsi amalandiridwa. Bokosi la magawo atatu lamamita atatu limapangidwa ndi ma voliyumu awiri agawo limodzi ndi ma thiransifoma apano, ndipo bokosi la mita imodzi la magawo atatu limapangidwa ndi ma voliyumu atatu agawo limodzi ndi ma transformer apano.Chophimbacho chimayikidwa pa gululo, ndipo kunja kuli ndi mamita a watt-hour for metering.
