Wind Turbine Slip Rings
DIRECT REPLACEMENT SLIP RINGS
Wind turbines require reliable transmission of power and data signals from the nacelle to the control system for the rotary blades. Costly downtime is eliminated by using fiber brushes and robust mechanical components in the slip ring design. Discover more ºìÐÓÊÓƵ slip ring advantages:
- Maintenance free for 100 million revolutions
- Minimal wear debris generation
- No lubrication required
- Wide operating temperature
- Lower life cycle cost
- High reliability
- No periodic inspections required
