Hybrid Lattice Tower

With hybrid lattice tower greater hub heights can be achieved.

It consists of the three components lattice tower, transition piece and tubular tower. The lattice tower is set on the foundation and is assembled directly at site. The transition piece connects the lattice tower to the tubular tower. The tubular tower consists of sections joint by means of bolted flanges.

The tower can be climbed from the inside and is equipped with working platforms, ladder with fall protection system and a service lift. The bottom cabinet sections are arranged in the transition piece.

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 special coating.

The foundation is project-specific, depending on the ground conditions and the local rules and regulations.
