Rail insulator is an essential part for railway fastening. It is installed between rail clip and steel rail, with the function of adjusting rail gauge and electrically insulating rail rail and concrete tie or sleeper.
A rail insulator is a component installed between a railroad rail and the tie plate, primarily used to electrically isolate the rail from the sleeper (or tie) while also adjusting the rail gauge, essentially preventing electrical current from flowing through the track structure and acting as a crucial part of the fastening system for high-speed or high-load trains; it is typically made from a reinforced nylon material like Nylon-6 or Nylon-66 with glass fiber for added strength and insulation properties. Function:
To electrically isolate the rail from the sleeper, preventing unwanted electrical currents and improving signal transmission quality.
Material:
Usually made from reinforced nylon (like Nylon-6 or Nylon-66) with glass fiber added for strength.
Installation:
Placed between the rail and the tie plate.
Importance for high-speed trains:
Considered a necessary component for high-speed or heavy load trains due to the increased stress on the track.
The rail insulators are made of nylon 6 or Nylon 66 with glass filler content 20% to 35%, with high performance on usage life and mechanical purpose.
