Siemens SWT-3.0 Blade Pitch Control Hub from China
The blade pitch control hub for Siemens SWT-3.0 wind turbines adjusts blade angles to optimize power output and protect against overloads in wind-powered generating sets of 8502.31.00. It includes hydraulic actuators and sensors integrated for nacelle mounting. This part qualifies for 8503.00.95.70 due to its principal use solely with these specific wind generators.

Import Tips
• Require OEM documentation linking the hub to SWT-3.0 models; inspect for pitch system serialization matching turbine specs; declare as wind-specific to avoid general machinery classification
