Insulators are devices installed between conductors at different potentials or between conductors and grounding components, capable of withstanding voltage and mechanical stress. There are many types of insulators with varying shapes. Although insulators of different types have considerable differences in structure and appearance, they are all 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, gradually evolving to the point where many disc-shaped insulators were hung at one end of tall, high-voltage transmission line towers. These are designed to increase the creepage distance. Typically made of glass or ceramic, they are referred to as insulators.
