Composite insulators are a special type of insulating device that plays a crucial role in overhead transmission lines.

Insulators are specialized insulating components that play a crucial role in overhead transmission lines.

Early on, insulators were commonly used on utility poles. Over time, they evolved to include many disk-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 known as insulators.

Insulators should not be affected by environmental and electrical load conditions.

Failures due to various mechanical and electrical stresses caused by changes; otherwise, the insulator would not serve its significant purpose and would damage the entire line's usability and operational lifespan.
