Composite insulators are a special type of insulation control that play a crucial role in overhead transmission lines.

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

Early on, insulators were commonly used on utility poles. Over time, they evolved to be attached to the top of tall, high-voltage transmission towers, with many disk-shaped insulators hanging at one end. These are designed to increase the creepage distance. Typically made of glass or ceramic, they are referred to 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 play a significant role and would damage the entire line's service and operational lifespan.
