Kreppisol: Versatile insulating material for electric motor construction
Dr. Dietrich Müller GmbH is a leader in the manufacture of stamped parts for electric motor construction. One of the key components for electrical machines is the material Kreppisol. This versatile insulating material offers outstanding properties that make it ideal for applications in electric motors, especially in slot and phase insulation.
Properties of Kreppisol
Creppisol is a combined flexible insulating material consisting of several layers. The inner layer is typically made of a polyester film according to IEC 674, while the outer layer is made of a special press paper that meets the requirements of IEC 641.
The main features of Kreppisol include:
- Temperature resistance: Insulation class B (up to 130 °C).
- High soaking ability: The press paper absorbs impregnating resins excellently, which ensures a strong connection of the winding components.
- Flat carrying surface: Facilitates machine processing.
- Flexible availability: As rolls, strips or sheets in various dimensions and thicknesses (0,07 to 1,0 mm).
Application Areas
Kreppisol is used in various areas of electric motor manufacturing, including:
- slot insulation: Protects the copper windings from short circuits.
- phase isolation: Separates different winding phases to prevent electrical arcing.
- layer insulation: Is inserted between winding layers to ensure insulation and stability.
Thanks to its impregnability and mechanical stability, Kreppisol is particularly suitable for high-voltage and precision applications.
