Composite Insulator
Composite insulators are extensively employed in electrical power systems to support and isolate live conductors, effectively blocking current leakage to ensure operational safety.
While structural designs vary across models, our composite insulators consist of three fundamental components: the Core Rod, Silicone Rubber Sheds, and Metal End Fittings (including Base Connectors & Oval Eyes).
-
Core Rod: Typically manufactured from epoxy glass pultruded rods (FRP), these cores are engineered to bear mechanical loads and provide internal insulation. They pass stringent "Color Penetration Tests" and "Water Diffusion Tests," demonstrating exceptional resistance to fatigue, cracking, and creep.
-
Insulating Material: We utilize premium high-voltage insulating silicone rubber. This polymer offers significant advantages, including thermal stability, ozone resistance, radiation resistance, and flame retardancy.
-
Superior Bonding: To optimize performance, both the core rod sheath and external sheds are molded from identical silicone rubber material. This ensures superior bonding strength due to the affinity between similar molecular structures.
-
Hardware Fittings: The metal fittings at both ends function as electrodes and facilitate force transmission, while providing secure connections to tower hardware and conductors.
Every composite insulator undergoes rigorous quality inspection before packaging to guarantee a robust connection between the metal end fittings and the core rod.
