Rail Tension Clamps charactors
Rail Tension Clamp, is also called rail clip, rail spring clamp, rail spring clip, it is made from spring steel, used for fastening the rails on kinds of railway lines.
Henan Xinda Railway Equipment Co.,Ltd is the main manufacturer and exporter of SKL rail tension clamps, which are responsible for the electrical insulation of the rails and their support. The rail tension clamps are widely used in laying reinforced concrete sleepers with a diameter of 13mm to 15mm, ranging from SKL1, SKL2, SKL3, SKL12, SKL14, SKL21,SKL24,SKL28,SKL30 etc.

W21 Rail Fastening System Specification
The W 21 system for conventional rail offers the same elasticity than the already approved W14. However, the tension clamp Skl21 with its fatigue strength of 2.5 mm and a deflection of 14.5 mm performs clearly more than the Skl14. For this purpose, the Skl 21 rail clip has been reinforced by a thicker wire diameter.
Due to the improved characteristics of the Skl21 rail clip, a highly elastic rail pad can be added in the W21 HS (High Speed) system: Perfect requirements for the load transfer in high speed tracks.
The W21 system becomes increasingly popular and since 2008 it has been being used in 30 countries on a total of about 3.000 km (1.900 miles), for instance in Bulgaria, Czech Republic, Finland, Germany, Kyrgyzstan, Lithuania, Slovakia, Argentina, Algeria and Azerbaijan.
The components of the W21 fastening system:
- Skl21 Tension clamp -4 units;
- Screw spike Ss 35/Uls 7 -4 units;
- Angled Guide Plate Wfp-14K12 -4 units;
- Plastic dowel -4 units;
- Rail Pad 148/185/6- 2 units;
W21 Rail fastening system is suitable for pre-assembly at factory, the manufacturer will warrant that the fastener system and fasteners are comply with last version of EN 13481 standard. W21 Raiilway Fastener System will be C class mentioned it EN 13481-1 standard and will warrant to use safely up to 300 km/h speed.
The system can be configured according to needs concerning different rail types.
We welcome your inquiry or order for the SKL21 fastening systems. And any components of this fastening system can be made in short time, such as SKL21 rail tension clamp.
