DM / DMD Laminates
DM / DMD Laminates
DM / DMD laminates are two or three layer insulation materials created by covering one or both sides of the polyester film with polyester fiber. The polyester film in this structure provides high dielectric and mechanical strength. Polyester fiber increases heat resistance with its capacity to absorb insulation liquids (varnish, resin, etc.). DM / DMD laminates can be used in applications with temperature class F 155°C.
Areas of Application
- Slot, Rotor And Phase Insulation For Electrical Motor And Generators Coils
- Core And Cylinder Insulation For Dry Type And Oil Filled Transformers
- Aluminium and Copper Conductors Insulation In Oil Filled and Dry Type Tranformers
- Inter And Final Layer Insulation For Dry Type Transformers And Electromechanical Applications
