Nabrawind has successfully completed the design and manufacturing evaluation of its new tower family as well as the first prototype.
Nabralift 3.0 has secured Component Certificate from UL Solutions during WindEurope 2024 in Bilbao, Spain.
The versatile 3.0 tower family includes six different configurations, adapting to various heights ranging from 100-200 metres, ideal for turbines over 6MW.
The assembly of the first Nabralift 3.0 tower was completed in late 2023 in Le Portel, France, as part of a project in collaboration with the French company Innovent and integrated with the Vensys 3.8-126 machine.
Another recent milestone for this tower has been obtaining certification of the adaptation of the generic design to a specific turbine (Vensys 126-3.8MW, installed in Le Portel).
Adaptations for other hardware of 5MW-6MW are already ongoing.
Nabralift is a self-lifting tower technology for turbines that overcomes limitations in the growth of unit hub height.
This structure consists of a three-column framework installed beneath the top of a tubular tower of a machine, incorporating a Self-Erecting System (SES) that facilitates the complete installation of the hardware (tower, nacelle, rotor) without relying on large-scale cranes.
The new 3.0 family incorporates improvements identified in previous projects, achieving weight reduction, enhanced logistics, more efficient assembly and the ability to support turbine loads of over 6MW, with rotors exceeding 180 metres.
All towers in the 3.0 family share the same transition piece and vary in the number of modules in the lower structure (from 0 to 5).
The resulting six models have already been certified by UL Solutions according to international wind regulations.
Nabrawind will install new Nabralift towers between 2024 and 2025 in Namibia, China and South Africa.
