Composite insulator and polymer insulator are two common types of insulators used in electrical power systems. While they serve the same purpose of insulating electrical conductors, they differ in their construction materials and designs. Understanding the disparities between these two types of insulators is crucial for selecting the most suitable option for specific applications. Composite Insulators: Composite insulators are made up of two main components: a core made of fiberglass reinforced rod and an outer sheath made of silicone rubber or other suitable materials. These insulators are designed to withstand high mechanical loads and harsh environmental conditions. The core provides mechanical …
