Insulators are devices installed between conductors at different voltages or between conductors and grounded structures, capable of withstanding the effects of voltage and mechanical stresses. There are a wide variety of insulators, each with different shapes. While the structures and appearances of different types of insulators may vary significantly, they are both composed of two main parts: the insulating component and the connecting hardware.
Insulators are specialized insulating controls that play a crucial role in overhead transmission lines. In earlier years, insulators were commonly used on utility poles, and gradually, they evolved to include many disk-shaped insulators hanging at one end of tall, high-voltage transmission towers. These are designed to increase the creepage distance. Typically made from glass or ceramic, they are referred to as insulators.
