Porcelain and glass insulators make up two-thirds of the insulators used in overhead transmission lines,During operation,these insulators frequently encounter defects and faults such as zero-value ceramic insulators,string failures,high self-breakage rates of glass insulators,and corrosion,When such issues arise,they can severely affect the safety and reliability of the transmission lines,Let's explore the causes of these defects and faults,as well as the corresponding countermeasures,
