The housing and sheds are made of premium HTV silicone rubber, providing excellent hydrophobic performance and resistance to contamination, moisture, and UV exposure.
The fiberglass reinforced epoxy rod serves as the main load-bearing component, ensuring high mechanical strength and reliable insulation performance.
Hot-dip galvanized steel fittings provide excellent corrosion resistance and secure mounting for long-term outdoor operation.
The silicone rubber surface maintains long-term hydrophobicity, significantly reducing leakage currents and flashover risks in polluted environments.
Compared with porcelain insulators, polymer line post insulators are significantly lighter, reducing transportation and installation costs.
Designed to withstand conductor loads, wind pressure, vibration, and environmental stresses encountered in power networks.
Provides outstanding performance under UV radiation, ozone, acid rain, salt fog, and extreme temperature conditions.
Composite construction eliminates the risk of porcelain breakage and improves system reliability.
