Background
Located at the edge of Kubuqi Desert, this 100MW solar plant faced triple extreme conditions: sandstorms (dust deposition >200g/m²), 70℃ diurnal temperature swing (-35℃~+45℃), and grid harmonics (THDu >8%). SH Power’s 35kV/1600kVA box-type transformers required 20-year reliability under desert corrosion, thermal derating, and harmonic interference while meeting State Grid’s voltage deviation standard (±10%).
