Electrical Excitation Wind Turbine Slip Ring
June 19, 2021
Wind power requires reliable power and signals transmitted from the nacelle to the control system for the rotary blades to control the pitch system. Prosper slip rings offer the good performance and reliable quality needed in the application. The slip ring also combines with encoder to get very accurate feedback of the speed to the system.
We also offer repair work to carbon brush slip rings.
