Wind Power Transformers Built for Cyclic Load and Remote Conditions.
Compact, IEC-compliant wind power transformers up to 6.5 MVA, 33 kV. Engineered for where the wind blows.
Product Overview
Designed for Where the Wind Blows. Not Where It's Convenient.
Wind power generation presents unique operating challenges, including cyclic loading, fluctuating power output, vibration, temperature variations, humidity, and remote installation locations. Transformers used in wind energy applications must deliver reliable performance under these demanding conditions while ensuring maximum turbine availability and minimal maintenance requirements.
