Slipring assemblies for energy and data transfer are being used for all products which do not allow any stationary current supply due to their rotary movement. Thus, the applications range from current transmission at purification plants to explosion-proof slipring assemblies with media lead-through for oil production vessels. Austbreck has been producing complex Slip Ring Assemblies with encoders and media feed-through for performance and control current monitoring in wind power plants under the product name ‘bako’ since 1994.

The Slip Ring Assemblies are subject to a very compact design and can be individually adjusted to customer requirements.

More than 12,000 supplied units stand for long-term experience and successful market positioning.

Our bako® Slip Ring Assemblies are used in wind turbines all over the world.


The slipring assemblies of series “FPKK” are well-priced standardised components. The basic types for 25, 50 and 100 A are available directly from stock. Due to the consequently implemented modular system also combinations between power- and data transmission are possible. The slipring assembly housing is made of shock-proof, glass fibre-reinforced plastic. A self-regulating heater can be used optimally. Together with the high protection class of IP 66 the slipring assembly is optimally suitable for the use in rough ambient conditions.
