Calcined mica tape and polyester glass fiber tape are both types of electrical insulation materials that are commonly used in the construction of electrical equipment.
Calcined mica tape is made from mica material that has been treated with a high-temperature calcination process. This process removes any impurities from the mica and makes it more stable and heat-resistant. Calcined mica tape is often used as a layer of insulation in high-temperature applications, such as in the construction of electric motors, transformers, and other electrical equipment.
Polyester glass fiber tape, on the other hand, is a type of tape that is made from a combination of polyester film and glass fibers. This type of tape is often used as a layer of electrical insulation in low-voltage applications, such as in the construction of electrical wiring and cables.
Both calcined mica tape and polyester glass fiber tape offer excellent electrical insulation properties and are important materials in the electrical industry. However, they are typically used in different types of applications. Calcined mica tape is generally used in high-temperature applications, while polyester glass fiber tape is more commonly used in low-voltage applications.
