Rail insulator
Rail insulator is installed between steel rail and rail tie plate. It serves to insulate rail clips and track bolts from the railway sleepers, as well as adjust the rail gauge. The function of rail insulator is the same as rail pad. As an essential part for the high speed and heavy railroad, they are effective to ensure the safety of rail track.
Our rail insulators are made of reinforced Nylon 6 and Nylon 66 (PA66), with glass fiber of 20%-35%. These materials are UV stabilized and can be colored with various colors.
Our rail insulators are simple to install and adjust, without being unbolt or adding multiple pads. They can be used in steel rails like 60kg UIC rail, 136RE rail, 90R, 75R, 50R and 60R etc. As for the package, we can provide double-layer woven bag and fumigation wooden pallets according to customers’ requirements.

Various types of rail insulator
To apply to various rail fastening system, we provide different types of rail insulator. Among these varieties, the most popular types are E-type, SKL and Nabla rail insulators.
E-type Rail Insulator
E-type rail insulator can coordinate with E-clip, rail shoulder and rail pads in E-clip rail fastening system.
SKL Rail Insulator
SKL rail insulator is used in SKL rail fastening system, installed with SKL tension clips, screw spike, rail pads, plastic dowel and flat washer. It is also known as guide plate.
Nabla Rail Insulator
Nabla rail insulator is a part of Nabla rail fastening system, combined with Nabla clips, screw spikes and spring washer.
