Mica tape for cable is a type of electrical insulation material used in high voltage power cables. It is made from mica paper, which is a thin and flexible sheet made from natural or synthetic mica minerals. The mica paper is reinforced with a backing material, such as glass cloth or polyester film, and coated with a heat-resistant adhesive. Synthetic mica tape is a newer type of mica tape that is made from synthetic mica instead of natural mica. It offers similar electrical and thermal insulation properties as natural mica tape, but with the added benefits of being more consistent in quality and less prone to defects.
