Wind Turbine Slip Ring with Standard Flanges Installed without Altering any Fan Equipment and Communication Signals and Protocols
Modern wind turbines rely on slip rings to transmit power and control signals from the hub to the blades, facilitating the operation and control of the wind turbine blades. These slip rings must maintain reliable transmission performance even in harsh environments, such as remote locations, low temperatures, and exposure to oil and seawater corrosion. The high reliability of the slip ring is crucial to ensure the normal operation of the wind turbine, which is one of the most critical components for stable performance.
As the pioneer in the development and mass production of wind turbine slip rings in China, Panlink has accumulated extensive experience through years of field operations. Our technology has continuously evolved, incorporating advanced precious metal fiber brushes and military-grade gold-plated ring contacts for multi-point connections. This ensures greater safety and reliability, enabling our slip rings to withstand extreme conditions such as high and low temperatures, vibrations, and swings while maintaining stable signal transmission. Our product range now extends from 250KW to 5MW fan impeller slip rings, meeting the diverse needs of the wind energy industry.
