Sealing solutions for renewable energy, energy transmission and distribution

A sustainable approach to natural resources is becoming increasingly important and is emerging as a question of survival in the long run. The demand for renewable energy from wind power and solar technologies is already climbing. Efficient, reliable, cost-effective, resistant to environmental influences, and trouble-free during installation and maintenance: That's what wind power and solar systems are supposed to be. Decentralized energy production and a dense network expansion require reliable and low-maintenance facilities to transmit and distribute energy.


Wind Power

Wind turbines need protection against the elements, including extreme temperature fluctuation. Sealing components that are made with innovative materials are able to withstand these severe variations. Freudenberg Sealing Technologies’ in-depth material expertise provides the basis for customized solutions, which includes our advanced Ventoguard material groups. The company’s network offers the world’s largest product range from a single source including superior manufacturing expertise and material compounds.  Freudenberg Sealing Technologies provides products for several applications inside wind turbines.

Dynamic seals for shafts and bearings:

Hydraulic seals and accumulators:

Vibration dampers

  • Half Shells for mounting and damping the main gearbox
  • Gearbox Mounting Block
  • Ultra Bushings for decoupling systems for compact Roto gearbox units
  • Layered Spring for mounting and damping the main gearbox
  • V-Mounts or Mounting Brackets for nacelle covers
  • MO-Mounts for several cooling units
  • Conical Mounts for mounting of control cabinets
  • Generator Mounts

Whether in the mountains of California or the Wadden Sea of Northern Germany – offshore or onshore – Freudenberg Sealing Technologies is always close to its customers. The company’s global application specialists will assist you with your requirements for materials and application specifications.


Transmission & Distribution

Freudenberg Sealing Technologies combines material and product know-how to provide the best solutions for static flange sealing against insulating gas in MV/HV switchgear. Standard EPDM and CR materials with excellent permeation characteristics and SF6 durability are ready for serial production and available in a variety of dimensions and product types. Improved EPDM and CIIR materials from the development pipeline will even exceed the current materials with lower permeation rates and will be ready for new gases like "g3" (Green Gas for Grid).

Self-fusing insulating tapes and putties provide easy handling and fitting, while reliably insulating transformer bus bars and cable terminations.

Product range for T&D:

  • Simmerring® oil seals and Forseals for switches, disconnectors, rotary feedthroughs and operating mechanisms
  • O-rings for flanges, cable terminations or fuses
  • Gaskets for switchboards
  • Bellows for rod protection
  • Pneumatic and hydraulic seals for operating mechanisms
  • Breaker door seals for arc-resistant switchgear
  • Self-fusing insulating tape and putties for cable terminations and bus bars

Whether high voltage or medium voltage – products from Freudenberg Sealing Technologies help you keep electricity under control and provide a reliable grid.


Energy Storage

Decentralized, renewable energy production requires reliable stationary storage capabilities. The increasing electrification of mobile powertrains of industrial vehicles requires light-weight battery systems with high capacities. Freudenberg Sealing Technologies drives innovation by creating new series products for stationary and mobile energy storage systems.

Product range for energy storage:
