Products Description
DMD Insulation Paper For Transformer is a flexible composite insulation material consisting of the following three-layer structure:
D--Non-woven polyester fabric: Enhanced mechanical strength and improved oil absorption performance.
M--PET Film: Provides high dielectric strength and enhanced voltage resistance.
D--Polyester non-woven fabric: Protects the film, improves flexibility, and increases impregnation.
Product advantages
1/ Temperature resistance: We offer two grades, B (130°C) or F (155°C), suitable for insulation applications in medium temperature environments.
2/ High mechanical strength: The three-layer composite structure improves tear resistance and folding resistance, suitable for scenarios requiring wear resistance.
3/ Excellent electrical insulation performance: The polyester film layer in the middle layer of the product provides good voltage resistance characteristics.
4/ Good impregnation performance: The double-layer non-woven fabric structure makes the product suitable for transformer oil or insulating paint impregnation, improving durability.
