Ceramic insulators are a specialized type of insulating device that plays a crucial role in overhead transmission lines. In earlier years, ceramic insulators were commonly used on utility poles, gradually evolving to have many disk-shaped insulators hanging at the ends of tall high-voltage transmission towers. These are intended to increase the creepage distance, typically made of ceramic, and hence termed 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 ensured, as ceramic insulators should not fail due to various mechanical and electrical stresses caused by changes in environmental and electrical load conditions. Otherwise, they would not fulfill their significant role and could damage the entire line's usability and service life.
