High Speed Turbines
Carbon brushes used on high speed turbine ring applications are the most critical applications in the world. Helwig Carbon has been supplying carbon brushes for these applications for over 85 years. Our H702 and H704 low friction graphite grades have been used extensively on Allis Chalmers, ABB, GE, and Westinghouse units around the world.
Due to the extremely high peripheral speeds it is difficult to maintain good contact with the ring.
This application is susceptible to selective action and an imbalance in current flow. This can lead to a build up of deposits on the inside of the brushholders which can impede the movement of the brush. In extreme cases the brush will be held up in the holder and lose contact with the ring. Regular maintenance checks can help identify and prevent these problems before they become serious.
