Metal ground anchor WIRE EX TENDONS

concrete

Since 2012, DYWIDAG has post-tensioned over 2,500 concrete and hybrid towers in Europe, North and South America, Africa, and Asia. Our installation teams can assist during the design and certification process, optimize installation with our prefabricated Wire-EX tendons—and add sensors for lifespan management. In addition to wire EX tendons, DYWIDAG windmill bolts will ensure a durable connection between tower foundation and tower or between tower segments. Wind turbine foundations can be stabilized using permanent strand anchors. The project consists of 47 new wind towers, each of which is 120m high and supports a turbine with an output of 2.1MW, allowing the park to reach a total output of 98.7MW. Each Wind Tower is post-tensioned with 6 Type 78 Wire EX Tendons installed inside the tower shaft. Protendidos DYWIDAG faced several challenges for installing the Wire EX tendons in towers without installed elevators while having to complete the work in a short time period. Type 78 Wire EX tendons were installed and stressed in approximately 22 towers in a period of just two months. Protendidos DYWIDAG’s experienced technicians were able to achieve a high level of installation safety and efficiency throughout the project’s construction period. In addition to the 282 Wire EX Tendons, Protendidos DYWIDAG also supplied and installed 1,128 36mm Ø, 2.3m long DYWIDAG Bars including accessories that were used on the last section of the tower to connect the concrete to the steel ring that supports the nacelle.
