Structure and Composition of Composite Insulators

Core rod:
Made of high-strength materials such as glass fiber reinforced epoxy resin, it provides excellent mechanical properties and tensile strength and is the core support component of composite insulators.
Sheath and sheds:
The sheath is usually made of polymer materials such as silicone rubber, which has good hydrophobicity, weather resistance, and aging resistance. The sheds design increases the creepage distance and improves the anti-pollution flashover capability.
End fittings:
Used to connect conductors and insulators, usually made of metal materials to ensure reliable electrical connection.
