Nabrajoint
Breaking logistics
barriers
Nabrawind Modular Blade System (nabrajoint) is a technology applicable to any wind turbine blade (existing or new) that allows manufacturing blades in two or more parts that are transported separately and assembled on site.
nabrajoint technology is based on a bolted connection between blade modules with conventional, controlled and robust assembly methods.
nabrajoint breaks all the logistic barriers for blade lengths over 70 m.
It is a game-changer technology for the new generation of XXL blades, with crescent difficulties in the transport to onshore Wind Farms and important associated cost increases.
modular blade system
Efficient solution
nabrajoint technology is conceived to be the most reliable, light and cost-effective segmented blade solution in the market. Our solution has been submitted to a strict certification process following the highest industry Standards, accrediting by means of different test campaigns a substantial increase of load carrying capacity with respect to the state-of-the-art joint solutions in the market.
This outstanding load carrying capacity, together with the optimized joint elements design results in the most competitive modular blade solution in terms of mass and cost.
patented system
The patented
XPACER® allows the pretension of a single stud which connects the threaded inserts of each blade segment
Our patented bolted joint is extremely simple, robust and maintenance-free.
modular blade system
Simple and
Flexible Process
nabrajoint is conceived to have a simple integration in the blade, without relevant modifications in the global design. The manufacturing process of the blade is not affected either: with no significant investments in the original production line, the process may be adapted in a flexible way to produce modular or standard blades as demanded.
The blade assembly on site is completed also with a straightforward process, with fast modules coordination and assembly. Furthermore, in order to reinforce this process, a lightweight automatic tool has been developed to assure a quick and controlled tightening of the joint elements even in hard environmental conditions.
The modularity of the blades will be mandatory by the year 2029
Our blades solution
nabrajoint scalability
is granted thanks to the different metrics available, assuring its applicability to any distance to blade tip
Metallic parts are minimized to reduce the joint mass.
