Electrical high-voltage and low-voltage insulation, components and fibre-reinforced materials for wind turbines

Krempel’s portfolio includes a range of materials that have been tried-and-tested over several decades and that can be used for the crucial elements of a wind turbine, whether these be generators, transformers, low-voltage motors or rotor blades.

The generation of energy from wind power is one of the central pillars of the move from nuclear and fossil energy sources to renewable and regenerative energy. Krempel is actively helping to shape this move, because wherever there are wind turbines, whether onshore or offshore, there’s a high chance that they’re using Krempel materials. We have been a leading partner to all renowned wind turbine manufacturers for over 20 years, and have been actively involved in crucial developments; indeed, it was our solutions that rendered these developments possible in the first place. As part of this process, we work in very close collaboration with the development teams of system and component manufacturers, and help design technical solutions for the particular challenges faced in the wind energy technology sector.

Our solutions for wind energy technology

We provide insulation materials, components and other materials for:

  • High-voltage generators
  • Gearless generators
  • Low-voltage motors of all sizes (e.g. for pitch and azimuth motors)
  • Transformers
  • Rotor blades

Krempel materials literally make light work of the demanding challenges faced by wind turbine components. Our composite materials, for example, have the perfect properties for use in wind energy applications: they are lightweight yet highly resilient and flexible at the same time. As well as composite materials, we also offer an entire range of other materials and components.

Our product portfolio for wind turbines

  • Electrical insulation for VPI, resin rich and low-voltage applications, e.g. mica materials and multi-layer laminates, provided as narrow tape, punched parts or moulded parts
  • Conductive tapes based on PET non-woven fabric and glass fabric
  • Rotor banding tapes made from glass, carbon and aramid fibres up to class H
  • Prepregs based on non-woven and woven fabrics, unidirectional, also available with epoxy resin binding agent
  • Insulating tubes, woven tapes, cords
  • Slot wedges made from pultruded profiles and mechanically processed from sheets, also magnetic and with swell mats included
  • Filament winding tubes for maximum force absorption and energy transmission
  • Glass-fibre and carbon-fibre-reinforced plastic profiles based on epoxy, polyester and vinyl resins
  • Three-dimensional moulded parts made from fibre-reinforced plastics
