The combination of different pipe diameters, wall thicknesses as well as separations can be modified as requested and perfectly adapted to the static requirements of the special tower. The use of standard components for tubular towers ensures rapid manufacturing and short restocking times. A special tower can therefore be installed almost as fast as a standard tubular tower. Although it needs only a small base area, the special central tower with Y-head permits high tower heights and is therefore ideal for urban use.
