My WES30 Foundation

For each WES30 a site specific foundation needs to be designed.

Over the years many different type of foundations have been designed to support WES30 wind turbines. The design of a foundation depends on tower height, type of soil and local regulations. Your WES dealer knows about these regulations. WES dealers have also access to examples of previous foundations and have an overview of all mechanical loads on the foundation. Your WES dealer will work with the local authorities and a local foundation expert that will design, calculate and build the right foundation for your WES30. If needed WES civil engineers can assist your local dealer designing a special foundation.

Key part in each foundation is the foundation anchor. The anchor is delivered a few months ahead of the turbine and is integrated within the concrete of the foundation. After hardening of the concrete the foundation is ready to be used. Parts of the anchor will stick out of the foundation and are used to support the lower section of the tower. The positioning of this anchor is critical. Each type of tower has its own type of anchor, its own set of fasteners and its own set of mounting instructions.

Each foundation is prepared to guide cables from the electrical topbox in the nacelle to the control cabinet. Each foundation is also prepared to conduct electricity from any lightning strike to the ground. Your WES dealer will make sure the mechanical and electrical parts of the foundation are within specifications and are in line with local- and safety-regulations.

For a WES30 on a 30 meter tower you need about 95 cubic meters of concrete.
