VSL’s external tendon systems for wind towers are designed to deliver long-term structural stability, durability, and ease of construction for modern wind energy projects.
Certified under European Technical Assessment (ETA), the system ensures reliable performance under dynamic wind and operational loads—both onshore and offshore.
A key advantage is the ability to re-tension the system at any time during the tower’s service life, helping maintain optimal structural performance over the long term.
