The insulating materials commonly used by electricians are classified into inorganic materials, organic insulating materials and mixed insulating materials according to their chemical properties.
(1), inorganic insulating materials: Mica, asbestos, marble, porcelain, glass, sulfur, etc., mainly for motor, electrical winding insulation, switch bottom and insulators.
(2) Organic Insulating Materials: There are shellac, resin, rubber, cotton yarn, paper, hemp, silk, and rayon, which are mostly used for the manufacture of insulation coatings, insulating coverings for winding wires, and the like.
(3), mixed insulation material: a variety of molding insulation materials made of the above two kinds of materials, used as electrical base, shell and so on.
