Product Description

Main uses
1. Electrical insulation
Isolate the rails from fasteners (such as bolts, washers, etc.) to prevent leakage of track current and ensure the reliable operation of the track circuit (used in automatic block sections or electrified sections).
Avoid stray current interfering with the signal system.
2. Mechanical fixation
Firmly press the bottom of the rail to keep the gauge stable and prevent longitudinal or lateral displacement of the rail.
Buffer the vibration and shock when trains pass through and reduce the wear of track components.
3. Anti-corrosion
Insulating materials (such as nylon, glass fiber reinforced polyamide, etc.) are moisture-resistant and chemically resistant, extending the service life of components.

 

Usage scenarios
Electrified railway
It is used in the traction power supply section to prevent current from passing through the fasteners and causing short circuits, which may affect the signal system or power supply safety.
2. Automatic block section
In the section where the track circuit is installed, insulating fasteners ensure electrical isolation between adjacent sections, enabling train position detection.
3. Special sections such as turnouts, Bridges and tunnels
These areas have higher requirements for insulation and stability, and high-strength insulating panels need to be used.
4. Urban rail transit (metro, light rail)
Reduce the electrolytic corrosion of surrounding metal facilities (such as pipes and cables) caused by stray currents.
5. Extremely cold, humid or corrosive environments
Insulating materials are resistant to low temperatures and salt spray, making them suitable for coastal areas or regions with severe industrial pollution.

 

Railway insulation panels are important components in the railway track system, mainly used for electrical insulation and mechanical fixation to ensure the normal operation of the track circuit and the safety of train operation.

 

By rationally using insulating panels, the safety, stability and signal transmission accuracy of the railway system can be significantly enhanced, especially on lines with a high degree of electrification and automation, which are indispensable.
