Composite Insulator

High-Performance Composite Insulators for Reliable Power Transmission

Composite insulators have become an indispensable component in modern electrical power systems, providing critical mechanical support and electrical isolation for live conductors while effectively preventing current leakage to ensure system safety.

Although structural configurations may differ by model, our composite insulators are precision-engineered around three core elements:

• Core Rod:​ Manufactured from high-strength epoxy glass pultruded fiberglass (FRP), the core rod is designed to withstand extreme mechanical loads while maintaining internal dielectric integrity. Each unit passes rigorous Color Penetration and Water Diffusion tests, ensuring outstanding resistance to fatigue, cracking, and long-term creep.

• Silicone Rubber Housing:​ We employ premium high-voltage insulating silicone rubber, selected for its excellent thermal stability, ozone resistance, UV radiation tolerance, and flame-retardant properties.

• Metal End Fittings:​ Featuring robust Base Connectors and Oval Eyes, these fittings act as electrodes and force transmitters, ensuring secure, standardized connections to both towers and conductors.

Superior Bonding Technology:​

To maximize structural integrity, both the core rod sheath and external sheds are co-molded from the same silicone rubber compound. This molecular-level affinity ensures a permanent, void-free bond with exceptional interfacial strength.

Every insulator undergoes comprehensive quality inspection prior to packaging, guaranteeing a flawless mechanical interface between the metal end fittings and the core rod.
