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.

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:

Plug & Seal for cooling pipes

Damp & Seal

The Damp & Seal damper seal from Freudenberg Sealing Technologies combines three functions into a single component.

Guide Rings

Guide Rings have the task of guiding the rods and pistons of pneumatic and hydraulic cylinders and preventing direct metallic contact with the cylinder housing.

Radiamatics

The requirements are high. Freedom from leakage is not only a "must" for drive shafts in shipping. Cleanliness is also of utmost importance in the paper industry with its high-speed rolls.

Wipers

Wipers in pneumatic and hydraulic cylinders protect the interior of the cylinder from the penetration of external contaminants when the rod is retracted.

Rod Seals

Rod Seals are primarily used in pneumatic and hydraulic cylinders and have the task of sealing the incoming and outgoing cylinder rod.

Static Seals

Portfolio Freudenberg Sealing Technologies

Cover Seals

Even if machine elements under pressure are firmly bolted to one another, there is still a so-called static seal gap that must be sealed.

O-Rings

Endless O-Rings with a circular cross-section: O-Rings are among the sealing classics par excellence.
