5. GE
• Condition Based Maintainance CBM
• Continue to produce power while parts, crane &
labor are resourced.
• Plan multiple maintenance events with same
resources.
• Reduce or limit the extent of damage to the drive
train & reduce repair cost.
• Hydraulic secondary brake.
• Modular tower system with hub height flexibility.

6. Fuhrlander
• On board transformer
• Drive train concept which is less load on gears,
better in safety and has lower noise emissions.
• Nacelle cover to capture air/wind.
