Rail Nylon Insulator

What is Rail Nylon Insulator

The rail nylon insulator also called insulating liner, it is used to adjust rail gauge and provide electrical insulation for the rails from the clips or shoulders and ties, installed between rail and tie plate, rail nylon insulator can adjust rail gauge and electrically insulating railroad rails, clips and bolts from the interior of a concrete tie or sleeper. Its function is similar to rail pad, only it is located above rail foot and it is thicker than rail pad. At present it is standard fastener part for either high speed or high load train.

Raw Mateiral and Application Fields

AGICO produces high quality rail nylon insulators, its material is PA6 or PA66 with 30% glass fiber. The insulator color can be white, yellow, green, etc. Our rail nylon insulators are manufactured to applicated for various rail section types and used together with our elastic clip. We are capable of supplying nylon insulators for UIC60 rail, 115RE rail, 75lb rail, BS80A rail, BS90A rail, BS100A rail, 52kg rail etc., and as a factory with molding center, we can design and develop any kind of rail nylon insulator according to customer’s requirements.
