Tubular Steel Tower
The tubular steel tower consists of up to four sections, joint by means of bolted flanges. The tower is built on the foundation using anchor bolts, which are set into concrete at the foundation.
The tower can be climbed from the inside and is equipped with working platforms and a ladder with fall protection system. Optionally, a service lift or climbing assistance can be installed.
The bottom cabinet sections are arranged in the tower bottom. The cabinet sections are connected to the generator and the top cabinet in the nacelle via power and control cables.
At the tower top the cables are routed through a cable loop. It allows the nacelle to turn several times in each direction without damaging the cables. The power cables between WTG and grid are routed through conduits.
The tower is protected against corrosion with a special sandblasting procedure and by applying an epoxy resin coating to the tower surface.
The foundation is project-specific, depending on the ground conditions and the local rules and regulations.
