◆ Kurasikirwa kwakaderera, mari shoma yekushanda, uye pachena simba rekuchengetedza simba;
◆ Murazvo unodzoreredza, usingatsvage moto, unoputika-usingaputsi uye usina kusvibiswa;
◆ Kushanda kwakanaka kwemvura-uchapupu uye simba rakasimba rekupisa kupisa;
◆ Kuderera kwechikamu chakaderera, ruzha rushoma uye kuchengetedza-kusina;
◆ High mechanical simba, yakasimba short-circuit resistance uye hupenyu hurefu hwebasa;
Mamiriro ekushandisa anosangana nezvinotevera zvinodiwa ndiwo akajairwa kushandiswa mamiriro:
a.Kukwirira pamusoro pegungwa hakufaniri kudarika 1000m.
b.Ambient tembiricha + 40°C zuva nezuva avhareji tembiricha + 30°C pagore avhareji tembiricha +20°C shoma tembiricha -30°C (kune ekunze transformers) hushoma tembiricha -5°C (ye indoor transformers).
C. Iyo waveform yemagetsi ekupa magetsi yakafanana neine wave.
d.Symmetry ye-multi-phase power supply voltage, magetsi emagetsi akabatana ne-multi-phase transformer anofanira kunge akaenzana.
