What is an  Electrical Insulator ?

Definition of Electrical Insulator

An electrical insulator is defined as a device used in electrical systems to prevent unwanted current flow to the earth, providing a very high resistance path.

Insulating Materials

Insulating materials must be strong, have high dielectric strength, high insulation resistance, be non-porous, and free from impurities.

Properties of Insulating Material

• High mechanical strength

• High dielectric strength

• High insulation resistance

• The insulation material contains no impurities

• Sclausura

• No entry

• Low receptive temperature
