2MW Air-cooling Double-fed Wind power Generator
The rotational speed of it ranges from 620r/min to 1380r/min. the product adopts special ventilation cooling structure, and its actual running temperature rise is less than 60K; Its stator and rotor windings adopt Class-H corona-resistant insulation structure and vacuum pressure impregnation, and have strong capability of adopting environment. The rotor is under dynamic balance in the whole speed range, and precision grade is G1.0. The vibration and noise limit of the entire machine is significantly lower than national standard.
Applicable environment: Inland, plateau (elevation ≤4000m) and low wind-speed conditions, etc.
