Ceramic insulators are specialized insulating components that play a crucial role in overhead transmission lines. In earlier years, ceramic insulators were commonly used on utility poles. Gradually, they evolved to include many disc-shaped insulators at the top of tall high-voltage transmission towers, which are intended to increase the creepage distance. Typically made of ceramic, these are referred to as ceramic insulators. Ceramic insulators serve two fundamental functions in overhead transmission lines: supporting conductors and preventing current from returning to the ground. These functions must be guaranteed, as ceramic insulators should not fail due to various mechanical and electrical stresses caused by environmental and electrical load conditions. Otherwise, they would not fulfill their significant role and could damage the entire line's usability and operational lifespan.
