Vi har ekspertisen, erfaringen og faciliteterne til at sikre den helt rigtige lynbeskyttelse af dine vindmøller

Lightning strikes are among the most common causes of shutdowns. As such, they constitute a phenomenon that proves extremely costly to wind turbine owners, increasing their OPEX and thus their Cost of Energy (CoE), if the wrong solution for protecting the turbine is chosen.



Customised Lightning Protection Systems in accordance with IEC 61400-24, Second edition
PolyTech’s comprehensive range of engineering and production skills in the field of lightning protection has made us the wind turbine industry’s preferred partner in this area.

We simulate, develop, design, test and manufacture Lightning Protection Systems (LPS), as well as associated components and solutions, to match individual specifications, wishes and requirements. This ensures you optimal peace of mind and a customised solution that accords with the latest standard (IEC 61400-24, Second edition).

On request, we can also handle the entire development project, from initial specifications to final delivery. Most often, however, development takes place in the form of close and confidential sparring with the customer’s own development department. In such cases we draw on the latest digital tools to ensure a process that is both flexible and secure.

Complete value chain
PolyTech’s customised Lightning Protection Systems are created through a unique combination of:

  • specialist knowledge in the areas of lightning, electromagnetism and electrostatic
  • rapid prototyping and customer specific solutions
  • specially developed polyurethane components with unique dielectric properties, thermal stability and extraordinary mechanical strength
  • specially developed high-voltage cables
  • high-volume production facilities
  • global delivery

All our solutions satisfy the latest standard (IEC 61400-24, Second edition), whose test requirements have been intensified and made mandatory, in contrast to the previous “informative” test sections.



Examples of customised LPS solutions from PolyTech:

  • Aerodynamic tip receptors with integrated internal electrical insulation
  • Protection of the interface between tip receptor and blade
  • Edge receptor systems with integrated internal insulation
  • Surface protection of blades
  • High-voltage insulated conducting systems
  • Current transfer systems between blade and hub, hub and nacelle, and nacelle and tower
  • Lightning detection systems for measuring lightning strikes in wind turbines
