What is wind turbine slip ring?

Slip rings in wind turbine are responsible for the power of whole wind generator system and the functions of control signals, data transmission. Its precision, reliability, working life will directly affect the performance of wind power generation system. Wind turbines require reliable electrical power and data signal transmission between the cabin and the rotating blade control system. Wind turbine slip rings rely on the design of elastic lap joint, rolling lap, sealing and ingenious movement structure, also the precision parts, reasonable material choose, etc. That form a stable and reliable rotary connection system. Wind turbine slip rings provide the performance and quality which are needed in this demanding environment.
Pitch control slip ring for wind turbine design trends are on at least two points, One, higher power transfer request for pitch slip ring since the power output and size are increased. Another, conditions monitoring for signal and data handing in the center as the additional demands. Facing the power peaks at the extremes of operation, we need to know the real situations and the brushes contact and brush technology must be durable.

Wind Turbine Slip rings - PHTW Series

Available for fully custom

Saving the planet by using renewable energy, GRAND is proud of as one wind turbine slip ring manufacturers. We supply wind energy slip ring with good low temperature resistance, high humidity, sand resistance, corrosion resistance, impact resistance, vibration resistance, stable performance and free maintenance characteristics. Fiber brush technology and rugged mechanical components are designed by GRAND which can avoided costly downtime maintenance. We know protect data lines from potential cross talk from power lines is important for electrical transfer system. so specially developed a supplier that has invested research and development into insulation materials. The improved insulation will have higher dielectric strength, better resist higher temperature.
Although GRAND offer modularized & standardized design for various application solutions as an original slip rings manufacturer. To create your most suitable wind turbine slip ring connector, please feel free to contact us.
