Insulators are devices installed between conductors at different potential points or between conductors and grounding components, capable of withstanding the effects of voltage and mechanical stresses. There are many types of insulators, each with a distinct shape. Although insulators of different types may have significantly varying structures and appearances, they are all composed of two main parts: the insulating component and the connecting hardware.
Insulators are specialized insulation components that play a crucial role in overhead transmission lines. In earlier years, insulators were commonly used on utility poles. Gradually, many disc-shaped insulators were hung at one end of tall, high-voltage transmission towers to increase the creepage distance. Typically made of glass or ceramic, these are referred to as insulators.
