Composite insulators, also known as polymer insulators, are electrical insulating devices used in high-voltage transmission and distribution systems. They are made of a composite material, typically a fiberglass reinforced polymer (FRP) core covered with a weather-resistant silicone rubber housing. Composite insulators offer several advantages over traditional porcelain insulators. Here are some of the key features and benefits of composite insulators: Overall, composite insulators offer a reliable, lightweight, and cost-effective solution for high-voltage transmission and distribution systems. Their unique properties make them well-suited for various environmental conditions and contribute to improved system performance and reliability.
