Prepreg DMD Composite Insulation Paper

Prepreg DMD composite insulation paper is an advanced composite material designed for demanding electrical applications. This prepreg material combines a robust polyester film (D), nonwoven polyester felt (M), and epoxy or polyester resin.

The prepreg DMD uses a DMD (Dacron-Mylar-Dacron) base, which provides mechanical strength and flexibility from the fibers and high dielectric strength from the film.

Primary Applications

• Dry-Type Transformers: Used as interlayer insulation for low-voltage foil-wound coils. It effectively reduces no-load losses and ensures stable operation in high-voltage environments.

• Electric Motors: Prepreg DMD composite insulation paper is an advanced composite material designed for demanding electrical applications. This prepreg material combines a robust polyester film (D), nonwoven polyester felt (M), and epoxy or polyester resin.

Heat-resistance: F Class 155℃ / H Class 180℃

Thickness: 0.10mm - 0.50mm

Electrical strength ≥ 40 kV/mm
