The Composite High Voltage Railway Insulator is a vital component in electrified railway systems. It ensures stable power transmission and operational safety for high-speed trains and metro lines. Made from advanced composite materials, it features outstanding insulation, pollution resistance, and mechanical strength, making it ideal for railway catenary and traction substation applications.
This railway insulator typically consists of three main parts:
Core Rod: Made from epoxy-coated fiberglass, offering excellent tensile and dielectric strength.
Sheds (Umbrella Skirts): Molded from premium silicone rubber with superior hydrophobicity and UV resistance.
Metal Fittings: Hot-dip galvanized steel or aluminum alloy, corrosion-resistant and mechanically reliable.
| Parameter | Value |
|---|---|
| Rated Voltage | 25kV / 35kV / 110kV |
| Power Frequency Withstand Voltage | ≥ 95kV (dry), ≥ 75kV (wet) |
| Lightning Impulse Withstand Voltage | ≥ 200kV |
| Mechanical Tensile Strength | ≥ 70kN |
| Creepage Distance | ≥ 1000mm |
| Operating Temperature | -40ºC to +85ºC |
| Expected Service Life | ≥ 30 years |
| Pollution Class | Class IV / Heavy pollution areas |
Superior Electrical Insulation: Withstands high voltage and arc conditions.
Lightweight Yet Strong: One-third the weight of ceramic types, easier to handle and install.
Excellent Hydrophobicity: Silicone rubber sheds reduce flashover risks in polluted environments.
Shock & Vibration Resistant: Ideal for high-speed railway environments.
Long Lifespan: UV and weather resistant for outdoor long-term use with minimal maintenance.
Composite high voltage insulators are widely used in:
Railway catenary power transmission systems
Metro and light rail power systems
Traction substations and power lines
High-humidity, plateau, and polluted environments along railway lines
We offer tailored solutions based on your requirements:
Custom voltage levels, creepage distances, and shed profiles
Optional metal fittings: ball/socket, flange type, etc.
Adjustable pollution grade, color, and product labeling
OEM/ODM manufacturing services available
