Application of rail insulator

The rail insulator is one of the key components of the high-speed railway fastening system. As a part of the connecting piece in the track fastener, it is responsible for adjusting the gauge and the current connection between the insulated rail and the ground. It not only realizes the railway’s reliability and stability but also ensures the elasticity and rigidity of the normal operation of the railroad track.

AGICO specializes in providing quality-assured railroad tracks and other track materials (rail fasteners). The rail insulator manufactured by AGICO can be applied on UIC60rail, 115RE rail, 52kg rail,75lb rail, BS80A rail, BS90A rail, BS100A rail, etc.

Rail nylon insulator

The rail insulator is mainly produced by an injection molding machine, and the material is mainly composed of nylon PA + glass fiber GF, also known as modified nylon. The color of the rail insulator depends on the customer’s requirements, and the required color can be produced by adding a certain amount of toner to the raw material particles.
