Product Overview & Features of Railway Fast Clip
| Item | Description |
|---|---|
| Product Name | Railway Fast Clip / Quick Installation Clip |
| Product Family | e.g., FC, e-Clip, KPO, Nabla |
| Application | Fastening rails in ballastless track systems (e.g., Slab Track, Embedded Rail), Urban Mass Transit (Metro), Tram, and High-Speed Rail. |
| Core Function | To provide a pre-assembled, easy-to-install elastic fastening system that maintains constant toe load, ensuring track stability and electrical insulation. |
| Key Advantage | Extremely fast installation and replacement, reducing labor costs and track possession time. |
| Material | High-Carbon Spring Steel (e.g., 60Si2Mn, 70Cr3) |
| Surface Treatment | Phosphating (Black/Grey) or Epoxy Coating (Typically Green) for corrosion resistance. |
| Insulation Components | Integrated insulating blocks (e.g., Nylon 6, GF66) to separate the clip from the rail foot and anchor. |
| Common Rail Sections | 54 E1, 60 E1, UIC 60, and other urban transit and high-speed rail profiles. |
Detailed Technical Parameters of Fast Clip
| Parameter | Value / Description | Remarks / Standard |
|---|---|---|
| Toe Load (Clamping Force) | 10 - 15 kN (Varies by type) | Optimized for stability in ballastless tracks. |
| Static Test Load | ≥ 25 kN | Ensures no permanent deformation under extreme load. |
| Deflection at Test Load | ~ 9 - 12 mm | Vertical displacement under test load. |
| Electrical Resistance | > 10^8 Ω (Per fastening assembly) | Ensures excellent electrical insulation for track circuits. |
| Corrosion Protection | ≥ 500 hours Neutral Salt Spray Test | For phosphated clips. Coated clips offer higher resistance. |
| Fatigue Performance | Passes 3-5 million cycles at ±5 kN dynamic load | Validates long-term durability under metro/HSR traffic. |
| Assembly Torque | 100 - 150 N·m (if applicable) | Torque for the shoulder/insulator screw. |
| Installation Tool | Manual Hydraulic Nibbler, Electric Torque Wrench | Specialized tools for efficient and correct installation. |
| Insulator Material | Glass-Fiber Reinforced Nylon (PA66+GF) or HDPE | Provides mechanical strength and electrical insulation. |
