Plastics for reliable electrical insulation parts

Once in operation, every wind turbine will need a high-performance and reliable electrical system. Generators, transformers and switchgear always must be coordinated with the planned output and build of the facility. We will help you in construction with our composites: They have been used in the electrical industry for more than 60 years. Electrically, mechanically and thermally highly resilient, they will enable you to develop reliable generators, transformers and switchgear with a high operating safety.

Your advantages

  • High operating safety
  • Long service life
  • Flame-retardant
  • High electrical resilience
  • High mechanical resilience
  • High thermal resilience

Typical areas of application

  • Onshore wind turbines
  • Offshore wind turbines
  • Small wind turbines

Application examples

Durostone® fasteners - high-voltage direct current transmission systems

Durostone® fasteners are electrically insulating and anti-magnetic. Some qualities are also part-discharge-free up to high electrical field strengths, particularity creep-resilient and flame-retardant. This will support the longevity of high-voltage direct current transmission systems.

Durostone® lead-through boards

Durostone® lead-through boards are a technical and economical alternative to aluminium and hard paper boards in the industrial furnace transformer industry. Their main function is the electrical insulation of the copper conductors and sealing the entire surface. Sheets of the glass fibre-reinforced plastic Durostone® stand out by excellent electrical insulation properties and high temperature stability in combination with high mechanical fastnesses.

Parts for generators

Depending on the output and the design, wind turbines use synchronous or asynchronous generators. With Durostone® (GFRP), we offer a material with outstanding electrical and mechanical properties to increase reliability and operational safety of your generators. Typical parts include slot wedges, slot inserts and winding head support rings.

Parts for switchgear

With Durostone® (GFRP), we offer a material with outstanding mechanical and electrical resilience that is used around the world in the construction of high-performance low- and medium-voltage switchgear for wind turbines.

Parts for transformers

Transformers must be operationally safe and reliable even at high usage temperatures and high electrical stress. We offer Durostone®, Lignostone® Transformerwood and Trafoboard® - materials specifically developed for these requirements. They meet the highest dielectrical and thermal requirements. Some of these materials have been used in transformers for more than 60 years. They will help you in construction of high-performance and operationally safe transformers.
