Transformers make it possible to distribute electrical current correctly. This makes them an essential part of modern society, where they are used for everything from large grids and wind turbines to kitchen appliances, electrical audio equipment and electric cars.
No matter where the transformers are used and how big or small they are, they share one crucial aspect. All transformers require components that insulate electrical currents.
It is a prerequisite for electrical insulation components that they are produced from materials specifically developed and produced for the purpose. Even the tiniest material defects can have major consequences for the operation of the transformers. With more than 100 years of experience in the field, we are able to offer composite materials that always ensure highly functional electronic components.
For electrotechnical purposes, we have developed the composite materials Etronit and G-Etronax, based on paper and glass respectively, both offering good electrical insulation properties.
Etronit is used in oil-filled transformers because the paper component can absorb the oil. Etronit also offers good electrotechnical properties and is available in a large selection of various qualities that make it possible to identify a material that is a perfect match for your purpose.
For transformers requiring a dry environment, we use our G-Etronax EP 11, which has high chemical resistance and durable insulation properties, even at high operational temperatures. G-Etronax is also our absolute strongest type of material with amazing resistance and outstanding electrotechnical properties.
These composite materials make for unlimited possibilities for developing transformer components, and we are happy to help you find exactly the solution you need to meet your requirements. Please do get in touch with our specialists for more information. You can also look up the specific properties of all our materials via our Material Finder, from which you can download both technical and safety data for our many different composite materials.
Since 1921, we have been working on the development and machining of electrical insulation components. This is one of our absolute core competencies, and it is a matter of great pride for us to deliver immaculate materials that always meet the strict requirements that are a matter of course in the electrotechnical world.
Perfectly functioning components is not just a question of using the right material composition that can meet the many technical requirements via the exact right properties. It is just as important that the material is machined in the right way within the appropriate tolerances, so that the component is functionally adapted to each transformer solution to perfection. Our specialised employees use automated cutting-edge machining facilities to ensure that our final components meet all these requirements.
This is why we can assure you that our core-insulating components are not just effective but also designed and machined to precision based on precisely your requirements. You are welcome to get in touch to hear more about the many possibilities for tailoring our solutions to your specific requirements, notably involving materials, machining, packaging and delivery.
