The insulator refers to a device whose prime function is to 'insulate'. An insulator is an electrical device that opposes the flow of current in a circuit. This quality of insulators to resist the motion of electrons is of great electrical advantage. They are often used as a protection device in certain circuits with high currents. What Are Conductors? In simple terms, an electrical conductor is defined as materials that allow electricity to flow through them easily. This property of conductors that allow them to conduct electricity is known as conductivity. The flow of electrons in a conductor is known as the electric current. The force required to make that current flow through the conductor is known as voltage. When a charge is transferred to such an element, it gets distributed across the entire surface of the ... Insulators: Types, Properties, Material, Causes of Failure and Applications The insulators or line insulators are used in overhead transmission and distribution lines. The overhead conductors are supported on the poles or towers. In order to avoid the flow of current through supporting poles, the insulators are used to support the line conductors. Hence, the line insulators are used to provide insulation to the power conductor from the ground. In a high-voltage transmission line, the ...
