Product Description
Rail 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.
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.
The insulators apply to rails such as 60kg (UIC) rail, 52kg rail, 136RE Rail, 90R, 75R, 50R, 60R etc. The rail insulator is mainly made by injection molding production, and it is mainly composed of 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 |
|---|---|---|---|
| Density | g/cm | 1.3-1.45 | 1.45 |
| Tensile Strength | Mpa | ≥170 | 178 |
| Elongation | % | ≤4.4 | 4.0 |
| Bending Strength | Mpa | ≥250 | 290 |
| Impact Strength (No gap) | KJ/m2 | ≥80 | 85 |
| Melting Point | ℃ | 250 - 270 | 270 |
| Insulation Resistance | Ω | ≥1×108 | 5×108 |
| Glass Fiber Content | % | 30-35 | 35 |
| Hardness | HRR | ≥110 | 118 |
Benefits: High mechanical strength, heat resistance, wear resistance, high rigidity, size stability.
