Nabrawind Technologies develops a new transition piece for the wind turbines of 4MW, 5MW and 6MW
Nabrawind technologies has developed a new transition piece specifically designed for turbines of 4MW, 5MW and 6MW.
The Transition Piece 2.0 is not just an update of the Nabralift transition. It also includes several advantages over the previous one.
Firstly, its scalability to the rating of each turbine. The Transition 2.0 can handle higher loads without significantly increasing the cost of manufacturing. This guarantees the competitiveness of the Nabralift tower for the next decade.
Secondly, the Transition 2.0 is also logistic friendly as its modularity facilitates the transportation. In particular, this piece is also transported separately and assembled on site. Exactly as the other parts of a Nabralift tower.
Finally, this piece reinforces Nabralift manufacturing capacity. For its characteristics, it is easier and quicker to manufacture, so it boosts the scale economy of Nabralift.
In detail, the new transition piece is 20 meters high and weighs between 120 and 150 tones, depending on the turbine loads, approximately. Its predecessor was just three meters high. This way, The Transition 2.0 also plays a role as one of the frames of Nabralift.
As it can be seen in the picture, its structure is composed by several parts which are the following:
- Upper Ring
- Monotubular tower segment
- Lower ring
- Corner connector
According to a report of Wood Mackenzie, by not later than 2023 half of the new installations in the world will correspond to 4MW, 5MW and 6MW WTG.
In this regard, Nabralift Program Manager, Ion Arocena, highlights that the Transition 2.0 “strengthens the competitiveness of the Nabralift tower while perfectly adapting to the new turbines that will dominate the market in the next decade”.
The first Nabralift towers that will use the new Transition 2.0 will be installed during this very same year in the projects that Nabrawind already has in progress.
