Durable Railway Fastener System for Enhanced Track Safety

Electrical Insulation Function

• Prevent leakage of track current and ensure signal system integrity (track circuits/ATP).
• Block conductive paths between rail and fasteners to reduce stray current corrosion.

Elastic Fixed Rail

• Provide stable clamping force to prevent track displacement.
• Buffer dynamic impact during operation and extend track service life.
• Adapt to harsh environments including humidity, salt-alkali, and extreme cold.

Electrified & High-speed Railways

Used in ballastless tracks for stable signal transmission (WJ-8 type, Vossloh spring strips, etc.).

Subway & Light Rail

Fully insulated fasteners to prevent tunnel structure corrosion from stray currents.

Special Sections & Harsh Environments

• Turnout areas, bridges, and tunnels to manage stress and isolate circuits.
• Coastal/saline-alkali areas using galvanized and salt spray-resistant parts.
• High-altitude regions with low-temperature resistance (-40ºC).

Key Selection: Match rail type (e.g., 60kg/m rail uses TB/T 3065 standard).

Testing: Measure resistance with a megohmmeter (Target: ≥10Ω).

Cycle: Gaskets (5-8 years), Spring bars (10-15 years).

Common Problems

Signal Failure: Check for damaged or contaminated gaskets; clean or replace parts.

Spring Bar Breakage: Check for overloading or material fatigue; replace and recheck installation torque.
