Operational safety and reliability of dry transformers is influenced by many factors. Constructors specifically need to consider the high operating temperatures and high dielectrical stresses. We offer composites specifically suitable for such requirements. They are characterised by high dielectrical and mechanical strength and meet the demands of heat categories F or H depending on material. This way, you can use our materials to construct long-lived and operationally safe dry transformers.
Very high operating safety
Long service life
High thermal resilience
High dielectrical and mechanical strength
Typical areas of application
Holders and spacers of Durostone® profiles
Parts made of Durostone® profiles, such as holders (figure) and spacers (Dogbones) for windings resist high mechanical, thermal and dielectric stresses and thus contribute to the construction of reliable and long-lived dry transformers. More about our Durostone® pultruded profiles
Parts machined from Durostone® sheets with narrow tolerances, such as pressure blocks (figure) combine high form stability with high mechanical and dielectric strength, thus offering a long service life. More about Durostone®
Iron core insulations and winding insulations
Iron core insulations and winding insulations made of Durostone® FHT with their high flexibility, thermal resilience and high dielectrical strength are particularly resilient and offer a very long service life. More about Durostone® FHT
Arrange technical advice
The performance and reliability of materials for dry transformers are influenced by a variety of factors. These criteria need to be considered in order to make the right choice. Examples:
Meeting heat categories F or H
