Product Description

Railway Arm-Type Composite Line Post Insulator: Reliable Insulation for Electrified Railways

Product Introduction

The railway arm-type composite line post insulator is a high-voltage insulation device specifically designed for electrified railway systems. It plays a crucial role in ensuring insulation and mechanical support between the conductor and support structures, thus preventing current leakage and ensuring the safe operation of trains.

Structure and Materials

This insulator adopts a multi-component composite structure. The core rod is made from high-strength epoxy fiberglass, offering superior tensile and bending resistance. The outer insulation sheath is manufactured from premium silicone rubber, providing outstanding weather resistance against UV radiation, acid rain, and industrial pollution. The end fittings are treated with hot-dip galvanization or zinc spraying to ensure excellent corrosion resistance and compatibility with railway attachment systems.

Technical Specifications

• Rated Voltage: 27.5kV (standard railway systems)

• Power Frequency Withstand Voltage: 70kV

• Lightning Impulse Withstand Voltage: 150kV

• Bending Load: ≥12kN

• Core Diameter: ≥20mm

• Creepage Distance: ≥600mm

• Operating Temperature: -40ºC to +85ºC

• Pollution Class: Class III and above

Performance Features

1. High Insulation Efficiency: Prevents current leakage, ensuring safe and stable system operation.

2. Compact & Lightweight Design: Ideal for aerial installations, reduces labor intensity.

3. Excellent Weather Resistance: Silicone rubber withstands UV, ozone, and temperature fluctuations.

4. High Mechanical Strength: Designed to endure vibration, wind loads, and other stresses in railway systems.

5. Strong Anti-Pollution Flashover Capability: Suitable for harsh environments like coastal and industrial zones.

Application Scope

This composite line post insulator is widely used in railway contact systems, traction substations, and rolling stock power supply lines. It is particularly well-suited for demanding environments such as plateaus, coastal areas, and regions with severe industrial pollution.
