Pole insulators are specialized insulating devices that play a crucial role in overhead transmission lines. In the early years, pole insulators were commonly used on utility poles, and over time, they evolved to include many suspended insulators at the ends of tall, high-voltage transmission towers. These are designed to increase the creepage distance. Typically made of silicone or ceramic, they are referred to as insulators. Insulators in overhead transmission lines serve two fundamental functions: supporting conductors and preventing current from returning to the ground. These functions must be guaranteed, as insulators should not fail due to changes in environmental and electrical load conditions, leading to flashover breakdowns. Otherwise, the insulators would lose their effectiveness, damaging the entire line's usability and service life.
