At BGB, we stay ahead of the evolving wind industry with a comprehensive range of wind turbine spare parts, including high-quality slip rings for leading OEMs such as Vestas, GE, Siemens Gamesa and many others. Our slip rings are engineered to endure the harsh conditions typical of wind applications—extreme temperatures, strong winds and airborne dust—delivering reliable transmission of electrical power and data between the stationary and rotating elements of the turbine. While primarily designed for wind turbines, they are also suitable for other sectors that require dependable rotary electrical connections. Backed by an experienced team of rotary specialists, we provide expert guidance to help you select the right solution for your needs. With a commitment to quality and customer service, BGB is a trusted manufacturer of wind turbine slip rings—contact our team with your enquiries today.

What is a Wind Turbine Slip Ring?

A wind turbine slip ring is a rotary interface that enables continuous transfer of power and signals between non-rotating and rotating parts. Built for longevity and consistent performance, it maintains connectivity as the hub, nacelle or blade systems rotate.

Applications & Variations

Choosing the correct slip ring is essential for reliable, consistent operation in wind turbines and other rotary systems. Common variants include:

• Through-Bore Slip Rings – Feature a central bore to route fluids, gases or cabling through the centre, often used for hydraulic fluid or coolant transfer to rotating components.

• Pancake Slip Rings – Low-profile, compact designs ideal where axial space is limited, including small-scale turbines and space-constrained assemblies.

• Fibre Optic Slip Rings – Transfer high-speed data via fibre optics, commonly used to carry sensor signals from the rotor to the control system.

• High-Current Slip Rings – Designed to handle elevated electrical loads, suited to high-output turbines and other high-power applications.

• Capsule Slip Rings – Small, sealed units for harsh environments, used to transmit power and data from the rotor to the generator where protection and compactness are key.
