Product Introduction
As a key component of railway tracks, the railway fastener system consists of embedded casings, spiral spikes, spring bars, gauge baffles, etc. It can be divided into heavy rail and light rail special fastener systems according to the type of rails. The heavy rail fastener system uses high-strength materials to withstand the large axle load pressure of freight trains and ensure the stability of the rails; the light rail special fastener system focuses on lightweight and convenient installation, which is suitable for the rapid construction and later maintenance of urban light rail, effectively reducing engineering costs while ensuring track strength.
The Nabla railway fastener system is widely used in various railway scenarios due to its unique structure and performance. Its core component, the Nabla spring clip, has a special shape design that allows it to fit tightly against the rails, provide long-lasting and stable buckle pressure, and prevent lateral and longitudinal displacement of the rails. Insulators serve as electrical insulation to prevent current conduction and ensure the safe operation of the power supply system. High-strength bolts, nuts and washers firmly combine the components. Whether it is on ballasted tracks with the elastic buffer of ballast or on ballastless tracks with elastic cushions to simulate elasticity, it can meet the track stability and elasticity requirements and ensure the safe and smooth operation of trains.
