The Electrical Property of Mica Powder

The Mica Powder insulation quality is the most important factor determining its industrial value. Mica insulation performance is determined by the electrical properties, the electrical property of mica are determined by testing breakdown voltage and breakdown strength. According to the test results of mica in each mining area, when the thickness of mica sheet is 0.015mm, the average breakdown voltage is 2-5.7kV and the breakdown strength is 133-407kV/mm.
