General Introduction

FXB Long Rod Suspension Composite Insulator is a high-performance polymer insulator designed for overhead transmission and distribution lines.

It consists of a fiberglass reinforced epoxy (FRP) core rod, silicone rubber housing and sheds, and hot-dip galvanized steel end fittings.

Compared with traditional porcelain and glass insulators, FXB composite insulators offer lighter weight, superior pollution resistance, and higher mechanical strength.

Working Conditions

Construction

Silicone Rubber Housing

The silicone rubber sheds provide excellent hydrophobicity and pollution resistance, maintaining insulation performance even under contaminated and wet conditions.

FRP Core Rod

The fiberglass core delivers high tensile strength while maintaining lightweight characteristics and excellent electrical performance.

Metal End Fittings

Forged steel fittings ensure secure mechanical connections and long-term reliability under heavy conductor loads.

Applications

Overhead Transmission Lines
Power Distribution Networks
Utility Substations
Railway Electrification Systems
Coastal and Industrial Areas
High-Pollution Environments
Renewable Energy Power Projects

Advantages

Excellent Pollution Performance

The silicone rubber surface maintains hydrophobic properties, significantly reducing leakage current and flashover risk in polluted environments.

Lightweight Design

Typically 70–90% lighter than equivalent porcelain insulators, reducing transportation, installation, and maintenance costs.

High Mechanical Strength

Designed to withstand heavy conductor loads, wind loads, and mechanical stresses encountered in transmission systems.

Superior Weather Resistance

Outstanding resistance to UV radiation, ozone, acid rain, salt fog, and temperature variations.

Enhanced Safety

Unlike porcelain or glass insulators, composite insulators do not shatter, reducing maintenance risks and service interruptions.
