- Gear Architecture: 1-stage planetary + 2-stage helical (optimized for load distribution)
- Compact & Lightweight: Up to 20% smaller than conventional gearboxes—ideal for nacelle space constraints
- High Efficiency: >97% mechanical efficiency
- Integrated Monitoring: Pre-installed ports for vibration, oil debris, and temperature sensors
- Corrosion Protection:
- Onshore: Standard industrial coating
- Offshore: C5-M marine-grade coating + enhanced sealing systems
- Service Life: Designed for 20+ years with modular repair and replacement options
Technical Highlights
- Input Speed: ~12–22 rpm
- Output Speed: ~1,200–1,800 rpm
- Lubrication: Forced lubrication with dual filtration and optional oil cooling
- Certifications: DNV-GL, IEC 61400-4, ISO 9001, ISO 14001
Ideal Applications
- Onshore wind farms in Gujarat, Tamil Nadu, Maharashtra
- Coastal and offshore-ready projects (future Indian EEZ developments)
- Repowering of legacy turbines (Suzlon, GE, Vestas platforms)
- Direct-drive hybrid retrofits requiring compact gearboxes
