The SG 3.4-132 wind turbine joins the Siemens Gamesa portfolio with a clear objective: to complement the product offer for medium- and high-wind sites where markets require nominal powers higher than 3 MW at an optimum Levelized Cost of Energy. Informed by 40 years’ experience in wind energy and a natural evolution of the Siemens Gamesa 2.X product series, this Class I/II solution ensures enhanced performance with high levels of reliability.
Technological highlights
Our onshore approach is focused on geared technology, in which we have extensive knowledge and expertise. The hallmarks of Siemens Gamesa turbines are: reliability, robustness and a modular, flexible design for optimum adaptation and maximization of production at any site and in all wind conditions.
Thanks to OptimaFlex technology, we go beyond the traditional off-the-shelf approach that results in products that are sub-optimal for many sites, and we deliver a uniquely tailored solution that is perfect for our customers’ specific needs. Optimized site design combined with a customizable product platform, based on flexible power rating, site specific towers and optimized BoP solutions, allow Siemens Gamesa to deliver reduced LCoE by increasing AEP while optimizing cost.
As an aerodynamic blade add-on, DinoTails® Next Generation reduces the sound power levels by using a serrated trailing edge mounted at the blade and adding finer combs in between the teeth. This world-leading noise reduction technology enables us to create value for our customers by maximizing AEP and reducing the LCoE in sites with noise constraints.
This turbine is equipped with blades made of fiberglass reinforced with epoxy or polyester resin. Together with the state-of-the-art aerodynamic profile, we can produce lighter blades having greater strength and improved dynamic behavior with less load transmitted to the rest of the components.
Turbine sensors continuously transmit data to our diagnostic centers, enabling the early detection of anomalies and preventing potential failures. By analyzing vibration patterns we can optimize your service plan and anticipate repairs before serious damage occurs.
Need Help?
The solutions we provide are driven by the benefits they deliver. This applies as much to our pursuit of absolute safety as to maximizing your return. Whether by inventing a new technology, evolving an existing product, or simply finding a smarter way of working, we strive to lower costs and raise returns on investments.
