Insulators are a type of insulating control that play a crucial role in overhead transmission lines. In earlier years, insulators were commonly used on utility poles. Over time, many disc-shaped insulators were hung at one end of high-voltage transmission line towers to increase the creepage distance. Made typically of glass or ceramic, these 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 usage and operational lifespan.
