Mica tape is a type of electrical insulation tape used in the construction of high voltage cables and other electrical equipment. It is made of mica paper, which is a high-temperature insulating material, and a variety of other materials such as glass cloth, polyester film, and other reinforcing materials. Mica tape is known for its excellent electrical insulation properties, high temperature resistance, flame retardancy, and low smoke emission in the event of a fire. It is commonly used in high voltage cables and other electrical applications where high temperature and flame resistance are required.
