The manufacturer of elastic clip fastening tells you that due to the high speed of the train, in addition to requiring the elastic parts of the fastener to have sufficient fastening pressure, considerable spring distance and strong ability to maintain the gauge, the high-speed railway must also have the following characteristics:

1. Less maintenance for elastic clip fastening. Once the high-speed railway is opened, due to the high speed and high density of trains, track maintenance can only be carried out within a short blockade. This requires that the components of the fastener have sufficient strength and durability.
2. Elastic clip fastening has good noise reduction and vibration reduction performance. As the speed of the train increases, the dynamic effect of the track increases sharply, so the fasteners are required to have good noise reduction and vibration reduction performance, that is, the fasteners are required to use cushion plates with better elasticity.
3. In order to ensure the safety of high-speed railways, the fasteners are required to have good insulation performance, and there should be sufficient impedance between the two rails to ensure the normal operation of the track circuit.
Comparison of insulation properties of various types of elastic clip fasteners According to the principles of fastener selection and performance requirements, among the existing fasteners in my country, all of them are new elastic clip fastening developed to adapt to high-speed and heavy-duty railways.
