Klassifizierung von Dämmstoffen

Die von Elektrikern üblicherweise verwendeten Isoliermaterialien lassen sich nach ihren chemischen Eigenschaften in anorganische Materialien, organische Isoliermaterialien und gemischte Isoliermaterialien einteilen.

(1) Inorganic insulating materials: mica, asbestos, marble, porcelain, glass, sulfur, etc., mainly used for motor and electrical winding insulation, switch bottom plates and insulators.

(2) Organic insulating materials: shellac, resin, rubber, cotton yarn, paper, hemp, silk, rayon, most of which are used to make insulating varnish and coating insulation for winding wires.

(3) Mixed insulating materials: various shaped insulating materials processed from the above two materials, used as the base and shell of electrical appliances.
