Product Description

The core application of railway insulating elastic strips
Electrical insulation function
Prevent leakage of track current, ensure the normal operation of railway signal systems (such as track circuits and ATP systems), and avoid signal interference or misjudgment.
Block the conductive path between the rail and the fasteners to reduce the corrosion of surrounding metal facilities by stray currents (such as subway tunnel structures).
Elastic fixed rail
Provide stable clamping force to maintain a tight connection between the rail and the sleeper, preventing track displacement or loosening.
Buffer the dynamic impact during train operation, reduce track wear and extend service life.
Adapt to harsh environments
The corrosion-resistant design is suitable for harsh environments such as humidity, salt and alkali, and high cold.

 

Typical usage scenarios
Electrified railway
High-speed railways and intercity railways
It is used in ballastless track to ensure stable signal transmission.
Typical fastener systems: WJ-8 type, Vossloh spring strips, etc.
Subway/light rail
Fully insulated fasteners are required in the tunnel to prevent stray currents from corroding the reinforcing bars of the tunnel structure.
Special section tracks
Turnout area
Isolate the track circuits of different sections to avoid signal crosstalk.
Bridges and tunnels
Compensate for the stress caused by thermal expansion and contraction while maintaining insulation performance.
3. Railways in harsh environments
Coastal/saline-alkali areas
Galvanized elastic strips and salt spray-resistant insulating gaskets are adopted.
High-altitude and cold regions
Low-temperature resistant materials (-40ºC) ensure elasticity.

Key points for selection and maintenance
Matching rail type: For example, a 60kg/m steel rail corresponds to the TB/T 3065 standard spring bar.
Insulation testing: Regularly measure the resistance with a megohmmeter (≥10Ω is qualified).
Replacement cycle: Insulating gaskets are generally 5 to 8 years, and the spring bar body is 10 to 15 years.

Common Problems and Solutions
Question 1: Insulation failure causes abnormal signals.
Countermeasures: Check whether the gasket is damaged or contaminated, and clean or replace the insulating parts.
Question 2: The spring bar broke.
Countermeasures: Check for overloading or material fatigue, replace the spring bars of the same model and recheck the installation torque.
