FZS High Voltage Polymer Line Post Insulator

FZS High Voltage Polymer Line Post Insulator is a composite line post insulator designed for overhead distribution and transmission lines.

Manufactured with a fiberglass reinforced epoxy (FRP) core rod, high-temperature vulcanized (HTV) silicone rubber housing, and corrosion-resistant metal fittings, it provides reliable insulation and mechanical support for conductors in various environmental conditions.

Features

1. Excellent electrical characteristics.

2. Good shock and collision resistance.

3. Good sealing performance.

Technical Specification 

Product Structure

Silicone Rubber Housing

The housing and sheds are made of premium HTV silicone rubber, providing excellent hydrophobic performance and resistance to contamination, moisture, and UV exposure.

FRP Core Rod

The fiberglass reinforced epoxy rod serves as the main load-bearing component, ensuring high mechanical strength and reliable insulation performance.

Metal End Fittings

Hot-dip galvanized steel fittings provide excellent corrosion resistance and secure mounting for long-term outdoor operation.

Applications

• Overhead Distribution Lines
• Transmission Line Structures
• Utility Power Networks
• Pole-Mounted Installations
• Compact Substations
• Railway Electrification Systems
• Coastal and Industrial Areas
• Renewable Energy Power Projects

Advantages

Excellent Pollution Performance

The silicone rubber surface maintains long-term hydrophobicity, significantly reducing leakage currents and flashover risks in polluted environments.

Lightweight and Easy Installation

Compared with porcelain insulators, polymer line post insulators are significantly lighter, reducing transportation and installation costs.

High Mechanical Strength

Designed to withstand conductor loads, wind pressure, vibration, and environmental stresses encountered in power networks.

Superior Weather Resistance

Provides outstanding performance under UV radiation, ozone, acid rain, salt fog, and extreme temperature conditions.

Enhanced Operational Reliability

Composite construction eliminates the risk of porcelain breakage and improves system reliability.
