Electrical insulation : basis of the safety in electromechanical industry

An electrical insulator, also known as a dielectric material, is a part of a component or an organ whose function is to prevent the passage of any electrical current between two conductive parts. An insulator has few free charges, they are trapped there, unlike a conductive material where charges are numerous and free to move under the action of an electromagnetic field. It is therefore necessary to protect humans, wildlife and machines from the dangerous effects of electricity in the event of an electric arc.
