The rod-type suspension composite insulator is made of a glass fiber-reinforced epoxy resin core rod and silicone rubber composite material, combining lightweight high strength with excellent electrical performance.
High tensile strength of the core rod (up to 100 kN or more), resistance to mechanical impact and fatigue, and adaptability to heavy-load power transmission requirements;
UV resistance and corrosion resistance of the material, eliminating the need for frequent maintenance, and self-cleaning of surface contaminants by rainwater.
Colors: Red, brown, gray, or as per customer's request
The model can be customized according to customer needs.
Product Detail
ZheXi Electric Power's Polymer Composite Rod-Type Suspension Insulator delivers unmatched resilience for critical high-voltage infrastructure.
Its core features include: strong hydrophobicity on the silicone rubber surface, which can effectively block leakage current in polluted environments and exhibit outstanding anti-pollution flashover capability;
It is primarily used in high-voltage and ultra-high-voltage transmission lines, coastal areas with frequent salt spray, industrial pollution zones, and other highly polluted environments. Additionally, it is employed in railway electrification, urban power grid renovation, and other scenarios where stringent requirements for weight and seismic resistance are imposed. It serves as a crucial component for enhancing the safety and economy of the power grid
At the heart of our Polymer Composite Rod-Type Suspension Insulator lies a dual-defense system:
Glass Fiber-Reinforced Epoxy Resin Core Rod: Withstands tensile loads ≥100 kN
Silicone Rubber Composite Housing: Provides hydrophobicity and environmental protection
