1.Lembani autilaini

VSM-12 mndandanda okhazikika maginito-mtundu m'nyumba mkulu voteji vakuyumu dera wosweka ndi magawo atatu AC 50Hz, oveteredwa voteji ya 12kV m'nyumba zosinthira zida. Kukhazikitsidwa ndi makina okhazikika a maginito a kampani yathu pakufufuza ndi chitukuko cha mabizinesi akumafakitale ndi migodi, kupanga magetsi ndi malo ocheperako ngati zowongolera zamagetsi ndi chitetezo. The mankhwala ndi mkulu kudalirika ndi moyo wautali makhalidwe, makamaka ntchito malo ndi zinthu kwambiri, monga ntchito pafupipafupi, mobwerezabwereza yochepa dera kuswa panopa.

2.Mikhalidwe Yachilengedwe

◆Kutentha kozungulira: -25 ℃ ~ + 40 ℃;

◆Kutalika: ≤1000m, mtundu wa mapiri ≤3000m;

◆Chinyezi chachibale: pafupifupi tsiku lililonse ≤95%, pafupifupi pamwezi ≤90%, kuthamanga kwa nthunzi tsiku lililonse

pafupifupi ≤2.2 × 10 MPa, pafupifupi pamwezi ≤1.8 × 10MPa. Pamene kutentha kumatsika mofulumira

mkulu kutentha nyengo, zikhoza kuchitika condensation.

◆Kuchuluka kwa chivomerezi: ≤8 mlingo;

◆Malo opanda moto, zoopsa za kuphulika, zonyansa kwambiri, corrosion ya mankhwala, komanso kwambiri

kugwedezeka.
