1. Chidule

Valavu Yotulutsa Madzi ya MV & HV Yokwera Voltagendi valavu yapadera yopangidwira makamaka ma transformer amphamvu amphamvu kwambiri (makamaka pazochitika monga ma transformer amtundu wa bokosi la ku America ndi malo osinthira omwe asonkhanitsidwa kale). Ntchito yake yayikulu ndikutulutsa mafuta ndi gasi zomwe zimapangidwa mkati mwa transformer chifukwa cha kulephera kwa insulation, kutentha kwambiri komwe kumachitika m'malo ena, kapena kutulutsa kwa arc. Imaganiziranso kudalirika kwa kutseka, kukana dzimbiri, komanso kusavuta kugwira ntchito. Kapangidwe kake kakugwirizana ndi miyezo yamakampani opanga magetsi aku America (monga mndandanda wa IEEE C57, ANSI/IEEE 386). Imagwirizana ndi mawonekedwe a ma transformer aku America (monga matanki amafuta ochepa ndi mawonekedwe a flange). Ndi gawo lofunikira kwambiri pakuwonetsetsa kuti ma transformer akugwira ntchito bwino.

Kuchepetsa kupanikizika kolondola, kupewa kuphulika kwa kupanikizika kwambiri

Chitetezo chosindikizidwa kwathunthu, palibe kutayikira

Kapangidwe koletsa kukokoloka kwa mafuta ndi kokhalitsa nthawi yayitali

Imagwirizana ndi ma transformer a ku America.

3.Kugwiritsa ntchitos

Amagwiritsidwa ntchito makamaka pa ma transformer amagetsi amphamvu aku America (monga ma substation a bokosi la ku America, ma modular transformers, ma substation okonzedwa kale), makamaka oyenera:

· 1). Zochitika zofunikira kwambiri pa chitetezo cha zida m'malo ogawa zinthu m'mizinda, m'mapaki a mafakitale, ndi zina zotero;

· 2). Malo owononga monga chinyezi chambiri, mankhwala opopera mchere kapena malo osungira mankhwala (amafunika kusankha ma valve oteteza dzimbiri);

· 3). Malo osinthira magetsi anzeru omwe amafunika kuyang'aniridwa pafupipafupi kapena opanda anthu (akulimbikitsidwa kuti akhale ndi ntchito yowunikira ma signal).
