In the field of railway construction and maintenance, the performance of fastener system plays a decisive role in track safety and stability. Both Fist rail fastener system and SKL rail fastener system are well-known products in the industry, but Fist system has obvious advantages in many key aspects.
Stronger fixing and vibration resistance: The spring steel clamp of Fist system is exquisitely designed, and the high-quality spring steel treated by special process is used, and its elasticity and toughness are much higher than ordinary steel. When facing the strong dynamic load and frequent vibration generated by high-speed train, it can continuously hold the rail tightly with excellent elasticity, effectively disperse and absorb energy, and prevent the displacement and creep of the rail. Taking the busy ore transportation railway line in Africa as an example, heavy-loaded trains run for a long time and at a high frequency. The spring steel clamp of Fist system ensures the long-term stability of the track with its excellent performance, while the spring steel clamp of SKL system is slightly inferior in elasticity retention and fatigue resistance under similar high-intensity working conditions, and the risk of displacement of the rail is relatively higher.
Excellent buffering and noise reduction effect: As an important part of the Fist system, the rail pad is made of highly elastic, wear-resistant materials with excellent damping properties. It is placed between the rails and the sleepers, like an efficient buffer barrier. When the train passes, it can greatly reduce the impact and vibration of the wheels on the rails, reduce the rigid contact between the two, reduce wear, and extend the service life of the rails and sleepers. At the same time, it significantly reduces the noise of train operation and improves the environmental comfort along the line. On railway lines in densely populated areas, the rail pads of the Fist system effectively reduce noise pollution. In contrast, the rail pads of the SKL system are weak in noise reduction and buffering performance, and it is difficult to meet the scene with strict requirements for noise control.
Excellent electrical insulation performance: At the moment when electrified railways are booming, the insulating fixing pins of the Fist system highlight the key value. It uses high-performance insulating materials, which can not only firmly connect the various components of the system, but also effectively prevent the leakage of current from the rails to the sleepers and the ground, ensuring the safe and stable operation of the railway power supply system, and eliminating equipment failures and personnel electric shock accidents caused by current leakage. In some high-speed railway electrification sections with extremely high electrical safety requirements, the Fist system relies on the reliable performance of insulating fixing pins to build a solid line of defense for the safe operation of trains. The insulating fixing pins of the SKL system have a certain gap with the Fist system in terms of the durability and stability of the insulation performance.
