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.
