Exceptional Electrical Insulation

Engineered for superior performance, Micanite washers possess an outstanding dielectric strength greater than 20 kV/mm. This high insulation capability makes them a preferred choice for applications requiring the prevention of electrical leakage or breakdown, especially in electrical equipment, transformers, and sensitive electronic assemblies.

Robust Environmental and Thermal Resistance

Micanite washers are resistant to moisture, chemicals, solvents, and oils, with a water absorption rate of less than 0.5% and oil absorption of under 1%. Their heat resistance extends up to 1000C, ensuring reliability in both high-temperature and harsh environmental settings, such as electric motors or heating elements.

Precision and Versatility

These washers are manufactured to precise tolerances (0.05 mm, customizable) and finished to a smooth, polished surface. The lightweight yet strong composition enables flexibility in custom sizing and shapes, meeting diverse requirements for electrical insulation and mechanical support within the industry.

FAQs of Micanite Washers:

Q: How are micanite washers typically used in electrical applications?

A: Micanite washers are widely used as electrical insulation in assemblies such as transformers, coil spacers, heating elements, and electric motors. Their high dielectric strength and heat resistance make them suitable for preventing electrical current transfers and providing stable thermal barriers in these systems.

Q: What is the process for customizing micanite washer dimensions and particle size?

A: Customization is achieved during the manufacturing process, where precise dimensions and particle size are tailored to client requirements. Customers provide their specifications, and manufacturers use advanced cutting and shaping techniques, ensuring tolerances within 0.05 mm and desired shapes, be it flat or slotted.

Q: When should I choose micanite washers over other insulating materials?

A: Micanite washers are preferred when excellent electrical insulation, high thermal conductivity, and robust resistance to moisture and chemicals are required. If your application demands operation in high temperatures (up to 1000C) or exposure to harsh environments, micanite washers offer superior performance compared to many standard insulating materials.

Q: Where are micanite washers most commonly applied?

A: They are most commonly found in electrical and thermal management systemssuch as transformer and coil assemblies, electric motors, heating elements, and high-voltage deviceswhere reliable dielectric and environmental resistance are critical.

Q: What benefits do micanite washers offer concerning environmental and safety standards?

A: Micanite washers are RoHS compliant, ensuring they do not contain hazardous substances. Their superior resistance to moisture, chemicals, and oils contributes to long-term reliability and safety in demanding industrial and electrical applications.

Q: How does the chemical composition of micanite washers impact their performance?

A: The silicate mineral composition with a Muscovite base, sometimes blended with Phlogopite, provides excellent dielectric and thermal properties while ensuring negligible CaO content (<0.1%). This results in enhanced durability, consistent performance, and stability under electrical and thermal stresses.
