Product Description

Main uses
1. Electrical insulation
Isolate the current between the rails and the sleepers and track beds to prevent short circuits in the track circuit signals.
Ensure the accuracy of the railway signal system and avoid misjudging the track occupancy status.
2. Mechanical fixation
Firmly clamp the steel rails, maintain the gauge and the slope at the bottom of the rails, and resist the longitudinal crawling and lateral displacement of the train.
Buffer the impact force of the train, reduce the geometric deformation of the track, and extend the service life of the track.
3. Anti-corrosion and vibration reduction
Insulating materials can reduce the rusting of metal parts and are suitable for damp or saline-alkali environments.
Some of the designs have elastic cushion layers, which can reduce the noise of the wheel-rail.

 

Typical usage scenarios
Electrified railway sections
Traction power supply area: To prevent the leakage of rail current to sleepers or ballast.
Signal zone boundary: Used in conjunction with the insulation section of the track circuit to ensure signal isolation.
2. Urban rail transit
Insulating fasteners are commonly used in subways and light rails to prevent stray currents from corroding the tunnel structure.
The elevated section needs to take into account both insulation and vibration reduction.
3. Ballastless track
The ballastless track of high-speed railways relies on insulating fasteners to fix the rails. For example, the Beijing-Shanghai High-Speed Railway adopts the WJ-8 type fasteners.
4. Special environments
In humid/saline-alkali areas: Coastal railways need anti-corrosion insulation.
Tunnels and Bridges: Prevent circuit failures caused by condensation or seepage.
5. Turnouts and crossing sections
The insulating fasteners in the turnout area need to withstand complex forces and isolate multiple track circuits simultaneously.

 

Intelligent monitoring: Embedding sensors to monitor the insulation status and fastening force of fasteners in real time (such as the European RailOpt system).
Environmentally friendly materials: The application of recyclable nylon or composite materials (such as Shinkansen fasteners in Japan).
Integrated design: Insulation and vibration damping functions are integrated (such as floating plate track fasteners).

 

Insulated track fasteners are the foundation for the safe and efficient operation of modern railways. Their selection needs to comprehensively consider the line speed, environmental conditions and signal system requirements.
