Insulators are specialized insulating devices that play a crucial role in overhead transmission lines. In earlier years, insulators were commonly used on utility poles. Over time, 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 and are typically made of glass or ceramic, hence the name "insulator." Insulators serve two fundamental functions in overhead transmission lines: supporting conductors and preventing current from returning to the ground. These functions must be ensured, as insulators should not fail due to various mechanical and electrical stresses caused by changes in environmental and electrical load conditions. Otherwise, the insulators would not fulfill their significant role, potentially damaging the entire line's usability and operational lifespan.
