Which insulating material is commonly used in aircraft wiring?

Plastic is commonly used as an insulating material in aircraft wiring due to its excellent electrical insulating properties, durability, and lightweight characteristics. This makes plastic ideal for protecting the conductive materials within the wiring from short circuits and environmental factors such as moisture and chemicals.

In aircraft, where weight savings and safety are paramount, plastics can be engineered to meet specific performance requirements and environmental conditions, such as resistance to high temperatures and flammability. By using plastic as insulation, aircraft can ensure reliable electrical performance while minimizing the risk of electrical failures.
