Wind turbines, by their nature and location, act as excellent lightning conductors. A lightning strike can lead to extensive damage to critical wind turbine components, including the main shaft and yaw bearings.
Gerken's lightning protection systems are tested to DIN Standard 62305 Class 1 (Offshore) and Class 2 (Onshore) and protect turbines worldwide.
Alongside our extensive range of carbon brushes, brush holders, slip rings, hub control units, earth dissipation and lightning protection systems, we also offer a wide selection of complementary products.
These include connectors, insulators, spindles, knuckle joints, bus-
Earth Dissipation Systems
The systems we offer for bearing protection work by providing an alternative path to earth for these discharge currents and are already widely used by leading OEMs.
Hub Control Units – Power and Signal Transfer
Our hub control units are complete slip ring and brushgear units designed to transfer power, signals and data.
The units are available in standard configurations for many turbines.
We supply both shaft-
Rebuilds of original units can be carried out on most types in use today, or we can develop a bespoke unit for you.
