Wind power technology in the Silbitz Group

The expansion of wind power technology is one of the most important elements in global plans to reduce further the use of fossil fuels and hazardous nuclear power. At the beginning of the development of wind power technology, wind turbines were still relatively small compared to the current standard, they had smaller rotor blade diameters and therefore had a much lower energy yield. Therefore, in the past the energy mix was very low. By means of continuous development and the definite plans to increase the share of wind power technology in power generation, more powerful, larger and technically more sophisticated wind turbines and components have been developed and brought into mass production. As a result of further developments and planning in wind power technologyboth today and in the future, the demands placed on the materials of the towers, rotor blades, gearboxes and, above all, the components of the wind turbine itself are becoming increasingly high. In the field of wind power technology, the Silbitz Group manufactures ready to install castings for wind turbines, including high performance and complex components made of a wide variety of materials according to your specifications and requirements.

Examples of complex wind power technology components

  • Planet bars, torque supports and housings
  • Castings for turbine systems
  • Rotor hubs and machine carriers in addition to kingpins
  • Numerous other applications ranging from 20 kg up to 45 t

Individual components for wind power technology

In the field of wind power technology, the Silbitz Group manufactures for you bearing housings, clutch housings, gearbox housings, main rotor shafts, rotor hubs and machine carriers with a respective unit weight of 0.5 to 45 tonnes. The material of the individual components consists of for example EN-GJS-400-18LT, a cast iron with spheroidal graphite and EN-GJS-500-14 a solid solution hardened material. All components for wind power technology can be mechanically machined for delivery and can also be provided with a high quality coating.

The future belongs to wind power technology

According to the publications of the Federal Association for Wind Energy, in the years 1985 to 2015 alone, the hub height of the largest wind turbines has increased by 3.8 times from 40 metres to up to 152 metres. The diameter of the rotor blades has increased by 6.5 times. Today, they now have a diameter of about 160 metres. With these large wind turbines, extremely high forces and loads are created, which have to be carefully integrated into the design process of this modern wind power technology, especially when considering the safety of humans and animals. While in 1985 the largest wind turbine with a rotor diameter of 20 metres and a power of 80 kilowatts produced 95 megawatt hours of electricity, in 2015 this had increased to 7,000 watts power with 15,000 megawatt hours.
