Suzlon Energy, one of the fastest growing wind energy companies in the world, is now fitting RotaBolts on all its 1.25 and 2.1MW wind turbines.
Suzlon Energy, one of the fastest growing wind energy companies in the world, is now fitting RotaBolts on all its 1.25 and 2.1MW wind turbines.
The tension monitoring fasteners have now become standard fit on the wind turbine blade connections.
James Walker RotaBolt's position as global leaders in bolting technology and tension control paved the way to the partnership with Suzlon who have a policy of adopting "the best of everything from around the globe" to deliver total wind power solutions.
Highly accurate tension at installation and throughout the life of the bolted joint is essential on the turbines, and Germanischer Lloyd certification requires that the turbine blade connections are checked annually.
With tension control being the critical factor in the reliability and safety of bolted joints, RotaBolt's unique ability to deliver tension control at installation and throughout the life of the bolted joint, made it a natural choice.
Suzlon has a subsidiary in Germany for technology development, a research and development facility in the Netherlands for rotor blade design, moulding and tooling, as well as wind turbine and rotor blade manufacturing facilities in India.
It was subsidiary AE-Rotor in the Netherlands who were responsible for the application of RotaBolt systems on the turbine blades.
"We are dealing with complex, high performance laminates and RotaBolts are easy to install and much easier to simply check for any loss of tension", commented Klaas Boerstra from AE-Rotor.
"We carried out extensive lab tests to check on the best approach to maintain tension".
"Without RotaBolts maintenance would be a lot of costly work".
The 1.25 and 2.1MW turbines are finding a growing market mainly in Africa, India and the States and Suzlon has built some of the largest wind parks in Asia, including the largest wind park of its kind in the world.
RotaBolt is increasingly being recognised as a global centre of excellence for bolted joint technology.
It is working closely with leading operators in industries such as oil and gas, chemical processing, power generation, civil engineering, environment, transport and defence, and is continuing to achieve new standards of safety and reliability through the application of its expertise and technology.
