Composite insulators are a specialized insulating device that plays a crucial role in overhead transmission lines.

Insulators are special insulation controls that play a crucial role in overhead transmission lines.

Early on, insulators were commonly used on utility poles. Gradually, they developed on the ends of tall, high-voltage transmission towers, with many disk-shaped insulators hanging. These are designed to increase the creepage distance, and are typically made of glass or ceramic, hence the name "insulator."

The insulator should not be affected by environmental and electrical load conditions.

Failure due to various mechanical and electrical stresses caused by changes; otherwise, the insulator would not play a significant role and would damage the entire line's usage and operational lifespan.
