What is the rail insulator


Railway insulator, also known as railroad insulator, rail insulation, railroad epoxy insulator, or rail nylon insulator. It is mainly used to adjust rail gauge and realize electrical insulation. It is installed between the steel rail and the tie plate, serving the purpose of both insulation and support. While its function is similar to that of a rail pad, but it is thicker. For high-speed or high-load trains, it is an essential railway fasteners.
GNEE is dedicated to providing quality assured railroad tracks and other rail fasteners. The rail insulator GNEE manufactures is applicable to various types of rails, including UIC60 rail, 115RE rail, 52kg rail, 75lb rail, BS80A rail, BS90A rail, BS100A rail, and others.
Characteristics of rail nylon insulators
The railway insulator is primarily manufactured through injection molding, It is mainly made of Nylon-6 or Nylon-66. These materials undergo UV stabilization, ensuring they are available in natural colors or can be customized based on customers specific requirements.
