PET Films with Glass Fiber Composited MGM Insulation Material for Electrical Motors and Transformer

Short Description:

MGM insulation material consisted of three layers, F-class adhesive to adhere the two sides of glassfiber cloth with polyester film. MGM insulation laminates with excellet mechanical strength, great electrical properties and good flexibility. The polyester film provides electrical insulation and mechanical strength, then fiberglass cloth enhances the mechanical strength and heat resistance of the material. The adhesive used is insulating and fire-resistant. MGM is used for slot insulation, liner insulation, interlayerinsulation of motor, transformer or other electrical appliance. We have various thickness for customers, vary from 0.13mm to 0.25mm, and regular master roll width is 1000mm. We could also customized small size width for customers as per requests.

Application:

Application Remarks：MGM composite flexible is mainly used as a slot liner,slot closure, phase-to-phase and turn-to-turn insulation in low or medium voltage electrical motors of Class F (155℃) or Class H (180℃) insulation system. In addition, it can also be used for coil insulation, end sealing insulation and gasket insulation of dry-type transformer.

1. Motors and generators: for coil insulation, slot insulation and turn-to-turn insulation to improve the efficiency and reliability of motors.

2. Transformers: for interlayer and turn-to-turn insulation to ensure the safe operation of transformers.

3. Cables and wires: as insulation or cladding to provide electrical insulation and mechanical protection.

4. Electronic equipment: used for insulation and protection of various electronic components
