Energy supply systems and bearings for wind turbines

Severe temperature fluctuations, strong winds, turbulence and sand storms: wind turbines have to work reliably even when exposed to harsh weather conditions. igus offers a wide selection of components made of high-performance plastics for wind turbines as well as in production equipment, transport and installation. The components required include robust, compact energy chains and flexible cables for torsional movements that reduce failures in towers, azimuth systems and blade adjustment, for example. Wear-resistant bar stock and high-performance plain bearings, which do not require lubrication or maintenance due to incorporated solid lubricants, are ideal for use in blade adjustment and brake systems.
