Product Description:
Typical Application Scenarios
Impregnated DMD materials for transformers are primarily used in insulation systems for high-end electrical equipment, with a particular focus on the following scenarios:
✅ Low-voltage coils of dry-type transformers: Used as interlayer insulation, end-sealing insulation, and lining insulation for foil windings, significantly enhancing short-circuit withstand capability.
✅ Class F motors: Used for slot insulation, phase-to-phase insulation, and turn-to-turn insulation, replacing imported HTEPP materials.
✅ Special requirement scenarios: Customizable in red, dark green, and natural white (red is most commonly used for process identification), and supports value-added processing, including slotting, die-cutting, and adhesive backing.
Key Points for Handling and Storage
Operation Instructions
Copper foil and DMD prepreg are typically wound alternately. Precise epoxy coating requires a glue impregnation machine. The processing of DMD fabric includes: feed rollers → glue impregnation rollers (fully immersed in the resin tank) → liquid removal rollers → glue scraping mechanism (excess resin is removed by rubber scrapers and recycled in an environmentally friendly manner) → winding process.
