What Is Thermal Stability and Why Does It Matter in Electrical Insulation?

Temperature is a key factor for any electrical equipment. During operation, it generates heat, and insulation must maintain its electrical and physical properties.Excessive heat in electrical applications can accelerate ageing and eventually affect insulation performance.This is the reason thermal stability is required. Thermal stability relates to how well an insulating material withstands heat without unacceptable deterioration. Mica is an inorganic insulation material used in demanding electr
