AGICO Nabla Rail Fastening System
The nabla clip rail fastening system is a system commonly used for railway track fastening. Its main component is the Nabla clip, which is used to clamp and secure rails (steel rails) to sleepers (wooden or concrete sleepers). The system takes its name from its core component, the nabla clip, which is typically made from high-strength spring steel and is elastic enough to grip the rail and ensure it is securely mounted on the sleeper. The nabla clip rail fastening system is widely used in railway construction in European and African countries. Comply with EN13481-5 standard. nabla clip rail fastening system mainly consists of nabla clips, insulators, screw spikes and spring washers.

The Features of Nabla Clip Rail Fastening System
- Reliable fixing performance: Nabla clip rail fastening system can reliably clamp the rail and ensure that the rail is firmly fixed on the sleeper. This helps prevent the rails from moving, deforming or loosening and maintains rail track stability.
- Elastic design: Nabla clips are elastic and can adapt to the expansion and contraction of the rails to cope with changes in different seasons and temperature conditions. This helps relieve stress on the rails, reducing stress-induced damage.
- Shock absorption and noise reduction effect: The elastic properties of nabla clips can absorb part of the train vibration and noise, improve the comfort of train driving, and reduce track noise.
- Relatively easy maintenance: The components of the nabla clip rail fastening system are relatively easy to install and replace, reducing the cost and time of maintenance and repairs. Maintenance crews can quickly replace damaged clips or other components to extend the life of rail tracks.
- High strength and durability: Nabla clips are usually made of high-strength spring steel, which has excellent durability and can maintain performance in long-term high-load operations.
