Composite insulator for electrified railway

Insulators are specialized insulation controls that play a crucial role in overhead transmission lines. In earlier years, insulators were commonly used on utility poles, gradually evolving to include many disc-shaped insulators hanging at one end of tall, high-voltage transmission towers. These are designed to increase the creepage distance. Typically made of glass or ceramic, they are referred to as insulators. 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 function and could damage the entire line's usability and service life.
