Plastics for dry transformers

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.

Your advantages

Typical areas of application

Application examples

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.

Pressure blocks

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.

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.
