Tubular Steel Tower
|
ENERCON tubular steel towers are manufactured in several individual tower sections connected using stress reducing L-flanges. Unlike conventional flange connections (such as those used in steel chimney construction), the welding seam of the L-flange is outside the stress zone.
Due to their relatively small circumference, shorter ENERCON tubular steel towers are mounted on the foundations using a so-called foundation basket, which consists of a double rowed circular array of threaded steel bolts. A retainer ring, fitted to the tower flange dimensions, is used to hold the individual bolts in position. When the foundation is completed, the lower tower section is placed on the bolts protruding out of the concrete surface and then bolted with nuts and washers.

- dispenses with complicated and costly welding work on site
- quick, reliable assembly with the highest quality standard
- full corrosion protection, applied under best production engineering conditions

A specially developed foundation connection system is used for taller ENERCON steel towers. A cylindrical structural element is set on the blinding layer and precisely aligned with adjusting bolts. Once the foundation is completed, the tower is flanged together with the foundation section.
Like all other components, tubular steel towers are subject to strict ENERCON quality standards. Quality assurance begins already in the design development stages to ensure that the prototype meets all requirements before going into series production.
