Product Introduction
The Nabla railway fastener system is a key technical product to ensure the structural integrity of railway tracks. Its core function is to provide continuous and stable buckling pressure for the rails. The system is based on Nabla springs, and is equipped with insulators with excellent insulation performance and high-strength fastening components to form a "buckle-insulate-fasten" trinity connection system. Whether it is dealing with the high-speed impact of high-speed railways or the huge loads of heavy-duty railways, the system can ensure that the rails and sleepers are tightly combined to reduce track deformation. Its outstanding advantages are ultra-long service life and low maintenance requirements, which can significantly reduce railway operating costs.
Nabla Type Rail Track Fastening System is a widely used railway rail fastener system in the world.
System features:
Elastic non-separable design: It adopts an elastic non-separable structure with shoulder and bolt buckling. This design helps to maintain the connection stability between rail and sleeper, and provides a certain elastic buffer.
Moderate buckling pressure: It can provide a buckling pressure of about 11kN, effectively fix the rail on the sleeper, reduce the longitudinal and lateral displacement of the rail, and ensure the safety and stability of railway operation.
Good elastic performance: It can provide elastic buffering when the train passes, absorb vibration energy, reduce the impact of vibration on the track structure, and can better adapt to the changes in train load.
Gauge adjustment ability: It has a certain gauge adjustment ability, which can be adjusted in steps within the range of -8~+4mm to adapt to different line requirements and thermal expansion and contraction of rails.

Product Packaging & Delivery
Modular plastic packaging units are made, each consisting of multiple small grids that can be spliced together, with a magnetic base at the bottom of the grid. Nuts, bolts, etc. are fixed in the grid by type, and multiple units can be spliced together horizontally or vertically. The combined whole is placed in a plastic outer box with a handle, and the empty space in the box is filled with EVA foam pieces. After the box lid is closed, it is reinforced with an anti-theft lead seal to facilitate quick sorting and transportation.
