Nabrawind installs the world's tallest steel wind turbine tower

Nabrawind Technologies has completed the installation of the world's tallest onshore steel wind turbine tower in Eslava, northern Spain
.
It is understood that the full-scale prototype of Nabralift is 160 meters tall and was
installed in two weeks.

The tower's unique design means it can be installed alongside the turbine compartment and rotor using a patented self-erecting system using hydraulic jacks, which can be lifted by adding small frame modules to the ground, eliminating the need for a large crane
.

The tower is 20% lighter than existing steel towers and can be transported
by standard truck.
The design of the tower also reduces the size of the foundation, and the installation process can be performed on a small assembly platform, reducing the footprint and reducing civil engineering costs
.

The new generation of onshore 3MW-5MW turbines will require very tall towers to accommodate large blades and achieve competitive wind speeds
in mainstream low-wind locations.
This larger rotor diameter means that turbines can produce more electricity more efficiently, resulting in fewer
turbines needed to reach the required generation capacity.
However, current tower technology faces design, logistics and installation challenges
that limit the growth of such products.

Nabralift Project Manager, Nabrawind Technologies, said, "Validating our technology with this prototype marks an important milestone
in our commercialization.
We confirm cost reductions of 15 to 20 percent compared to traditional methods such as steel pipe or hybrid towers, and by next year we aim to produce and install up to seven towers
with heights between 135 and 200 meters.

It was revealed that the prototype will be tested after installation to prove a 25-year service life
through fatigue load tests.
Once the project is complete, Nabrawind Technologies will install up to seven towers with heights of up to 200 meters
in 2019.
