Railway insulators, also known as rail insulators, railroad insulators, rail nylon insulators, are installed between the rails and tie plates to adjust the rail gauge and electrically insulate the rails, rail clips and rail bolts inside the concrete sleepers. It functions the same as the rail pad, but is thicker than the rail pad. For high-speed or high-load trains, it is an essential rail fastener.
Features of railway insulators:
Insulators are suitable for 60kg (UIC) rails, 52kg rails, 136RE rails, 90R, 75R, 50R, 60R and other rails. Rail insulators are mainly produced by injection moulding, the main material is Nylon-6 or Nylon -66, and the glass filler content is 20% to 35%, depending on the specification. These materials are UV stabilized and available in natural colors or upon request.
|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|
Advantages: High mechanical strength, heat resistance, wear resistance, high rigidity and dimensional stability.
Packing: double-layer woven bag + fumigation-free wooden pallet or according to customer requirements.
Types of Railway Insulators:
We supply E-rail insulators and tie plates for SKL rail fastening systems and Nabla fastening systems. The material of railway insulators is usually reinforced nylon 66 (PA66), and the color is white, dark brown or black. Materials and colors can also be customized according to customer's requirements.
1. E type railway insulator
Type E railway insulators are used in Type E clip fastening systems, used with Type E clips, rail shoulders and rail pads.
2. SKL Railway Insulators
SKL Rail Insulators, also known as Guide Plates, are used in the SKL Fastening System and are used in conjunction with SKL Tension Clamps, Screw Spikes, Plastic Dowels, Flat Washers and Rail Pads.
3. Nabra Railway Insulator
Nabla railway insulators are used in Nabla clip rail fastening systems, as well as other railway fasteners such as Nabla clips, screw spikes and spring washers.
