Product Description

Product Introduction

The 10kV-220kV substation post composite insulator is a high-performance insulation component used in power substations for busbars, disconnectors, breakers, and other high-voltage equipment. It integrates advanced composite material technology and a robust post structure, providing excellent insulation, pollution resistance, and mechanical strength.

Structure and Materials

This insulator is composed of a fiberglass rod core, silicone rubber weather sheds, and metallic end fittings:

• Core Rod: Made from high-strength epoxy fiberglass, offering superior mechanical performance.

• Shed Housing: High-quality liquid silicone rubber molded with excellent hydrophobicity, anti-pollution, and UV resistance.

• Metal Fittings: Hot-dip galvanized steel or stainless steel fittings ensure firm connection and corrosion resistance.

The composite design delivers optimal performance, lighter weight, and easier handling than traditional porcelain insulators.

Key Features

1. High Pollution Resistance: Silicone rubber offers self-cleaning and water-repellent properties.

2. Superior Mechanical Strength: Fiberglass core ensures high bending, compression, and tensile capacity.

3. Lightweight Design: Easier installation and handling compared to porcelain alternatives.

4. Excellent Aging Resistance: UV and weather resistant for long-term outdoor service.

5. Safe and Durable: Non-fragmenting upon damage, safer for maintenance and inspection.

Application Scope

This insulator is widely used in substations, power plants, and urban/rural distribution systems. It performs reliably in high-pollution, high-altitude, coastal, desert, and humid environments.
