WP7286 Pitch Slip Ring

The WP7286 is the next generation pitch slip ring for the GE wind turbine. This design utilizes the same high-reliability, no maintenance, fiber brush technology as our AC7008 pitch slip ring family –– which has been a solid performer and allows GE wind assets to operate with higher productivity and a lower cost of operation by eliminating costly downtime related to pitch slip ring issues and required maintenance.

Enhancements

The WP7286 has been further enhanced to improve installation and performance:

• Redesigned to make the slip ring smaller, reducing size
• 23.13 kg (51 lb), easier to lift, 9.07 kg (20 lb) less than AC7008 slip ring
• A convenient handle makes the unit easier to handle
• Improved sealing to keep the slip ring area cleaner, improving life and operation
