DMD insulation paper/non-woven fabric and polyester film6630
Temperature classification: B class 130C
6630 DMD INSULATION PAPER is laminated with two layers of polyester fiber non-woven fabric and a single layer of polyester film in the center,
Characteristic: As slot, interurn and liner insualtion of B grade electrical machine and electrical equipment.
Advantage: This material has comparatively good heat-resistance, dielectrical property and good mechanical property, along with sound soakage capability.
Applications: Class B DMD mainly used as slot liner, slot closure, phase and turn-to-turn insulation in electrical motors. It can be used as interlayer insulation in transformers and other electrical appliances.
