What Are Composite Insulators?
Composite insulators are high-voltage insulation components made from multiple materials, typically including: Fiberglass-reinforced epoxy resin (FRP) core rod for mechanical strength and tensile support.
Silicone rubber or high-temperature vulcanized (HTV) silicone housing for external insulation, hydrophobicity, and pollution flashover resistance.
Metal end fittings for secure connections to equipment and support structures.
Compared to traditional glass or porcelain insulators, composite insulators are lighter, mechanically stronger, and highly resistant to pollution and aging, reducing maintenance requirements and installation complexity.
