Our insulators undergo comprehensive electrical, mechanical, and environmental testing to ensure reliable performance.
We maintain strict quality control throughout production, from raw materials to final inspection. Our management systems are certified under ISO 9001 (quality), ISO 14001 (environment), and ISO 45001 (safety), ensuring consistent product quality, environmental responsibility, and workplace safety.
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.
