Wind turbine slip rings are essential components that enable the transfer of power and data signals between stationary and rotating parts of a wind turbine. They are built to withstand the harsh environmental conditions that are common in wind turbine applications, including extreme temperatures, strong winds and dust.

FAQS
There are several variations of wind turbine slip rings. Each of these variations have unique features and benefits, making them suitable for different applications and requirements. Choosing the right type of slip ring is essential to ensure reliable and consistent performance in wind turbines and other rotary applications.
Some of the most common types of wind turbine slip rings include:
Through-Bore Slip Rings: designed with a central hole or bore that allows the transmission of fluids, gases or cables through the centre of the slip ring. It is commonly used in wind turbines to transfer hydraulic fluid or coolant to the rotating components.
Pancake Slip Rings: compact and flat slip rings that are ideal for applications where space is limited. They are commonly used in small-scale wind turbines and other applications where the size of the slip ring is critical.
Fibre Optic Slip Rings: designed to transmit data signals using fibre optic cables, commonly used in wind turbines to transfer data signals from the sensors on the rotor to the control system.
High Current Slip Rings: designed to handle high electrical currents, making them ideal for wind turbines with high power output. Commonly used in other applications where high-power transmission is required.
Through working closely with wind farms we came to understand the maintenance challenges associated with this component and looked to improve it further. The biggest improvement found was on the encoder mount, from speaking with wind turbine technicians, it was found that the encoders did not last as long as the slip rings:
“The encoder would alarm the SCADA system and need to be replaced. The glue bonding the encoder to the shaft would melt under high temperatures and no longer remain true to the shaft.” Wind Turbine Technician
This would have to be removed with force (if removed at all). To overcome this issue, we developed an over-moulded shaft to serve as a new encoder drive which can easily be replaced and then re-machined as part of a refurb. This prevents damage of the slip ring during encoder removal and gives a greater chance of success when the slip ring eventually requires refurbishment saving more money.
