Rail nylon insulator is installed between rail and tie plate, for adjusting rail gauge and electrically insulating railroad rails, clips and bolts from the interior of a concrete tie or sleeper. Its function is the same as a rail pad, but it is thicker than rail pad. For the high speed or high load train, it is a necessary fastener part .
Properties of rail insulators
The insulators apply to rails such as 60kg (UIC) rail, 52kg rail, 136RE Rail, 90R, 75R, 50R, 60R etc. It’s material:Nylon-6 or Nylon-66 with glass filler content 20% to 35% depending on specification. These material are UV stabilized and available in natural color or as per requirement.
The properties of our rail insulators are as follows:
|Technical Parameter||Unit||Technical Requirement||Value|
|Impact Strength (No gap)||KJ/m2||≥80||85|
|Melting Point||℃||250 - 270||270|
|Glass Fiber Content||%||30-35||35|
Packaging Detail: Double-layer woven bag + Free fumigation wooden pallet or according to clients' requirement.
Delivery Detail: Shipment within 35 days upon the receipt of order
We supply E-type rail insulators and guide plates for SKL rail fastening systems and Nabla fastening systems. The material of rail insulator is usually Reinforced Nylon 66 (PA66), with the color white, dark brown or black. Materials and colors can also be customized according to the customers’ requirements.
E-type rail insulators
E-type rail insulators are used in E-clip fastening systems, together with E-clips, rail shoulders and rail pads, whose function is to cushion the passing train’s stress onto the rail and make the rail back to position afterwards, similarly used as a rail pad under the rail track.
SKL rail insulators
SKL rail insulators are also called guide plates, used in SKL fastening systems, combined with SKL tension clips, screw spikes, plastic dowels, flat washers and rail pads.
Nabla rail insulators
Nabla rail insulators are used in Nabla clip rail fastening systems, working together with other fastener parts including Nabla clips, screw spikes and spring washers.
