Are you experiencing problems with your Slip Rings?... Cleaning too much? Sticky black residue inside? Waiting on units to arrive? Paying too much for parts?...
Resulting in... CLIMBING towers too much Turbine DOWNTIME Increased dept. COSTS
BGB Upgrade Solutions
Aftermarket innovation : Addresses the failures of the previous units while still fulfilling the Siemens specification Reduce O&M costs : Modular design means that manufacturing costs are lower and parts are common to all versions of the unit Always have the right part : Available in all variants of CS and VS No maintenance : No dust generation or cleaning requirements due to silver fiber technology Work with a trusted technology partner : Incorporates successful design and experience from BGB’s successful Vestas units Improved seal : End access and no maintenance means the concentricity of the cover does not change over time. The weep holes prevent oil ingression into the main body
BGB's improved seal offers greater protection against hydraulic oil ingress from the hydraulic joint
(Pictures left and right show oil ingress in competitor products)
BGB Design Advantages: Signal and Power channels utilize the same brush and ring interface to: reduce unit cost, reduce temperature and increase transmission safety factor
Reduce component lead times : Made in the USA and stocked in the UK
Designed to IP65

Origins…
Did you know?
BGB has been producing slip rings for Bonus turbines since the Bonus 1MW which was first produced in 1996. While having a relatively low production volume it had the characteristics typical of the Siemens turbines of today, such as the iconic nacelle shape and three stage asynchronous gearboxes that served as a foundation of design for the Siemens Bonus turbines after the Siemens takeover in 2004.

AN Bonus 1.3/2.0MW WCT2 Paratec upgrade
• Around this time BGB
supported Bonus in their failure investigation
• Issues addressed with flashing, contamination, and brush degradation
• Upgrade retrofits available
• Wiring diagrams and service information available on request
Lightning brush holder
• BGBs Lightning Protector Brush Holders are robust units that are designed to dissipate lightning energy and thus defend critical components (typically main shaft and yaw bearings) • A low impedance path is created through the rotational interface (hub to
nacelle) from the lightning protection conductor to the ground, therefore protecting the main bearing
