Rail Insulators (Gauge Plates,Guide Plates)

• Rail nylon insulator is installed between rail and tie plate, for adjusting rail gauge and electrically insulating railroad rails, clips and bolts from the interior of a concrete tie or sleeper. Its function is the same as a rail pad, but it is thicker than rail pad. For the high speed or high load train, it is a necessary fastener part .
  
  The insulators apply to rails such as 60kg (UIC) rail, 52kg rail, 136RE Rail, 90R, 75R, 50R, 60R etc. It’s material:Nylon-6 or Nylon-66 with glass filler content 20% to 35% depending on specification. These material are UV stabilized and available in natural color or as per requirements.HuiBo Railway can supply different kinds of Rail insulators which suit E clips ,SKL and Nabla fastening systems ,others depend on the specific requirementsfrom the clients .

• Rail pads are elastic polyurethane mats which are interposed between steel rails and tie sleepers to protect the sleeper top from wearing and impacting. The starting stiffness of a rail pad is designed to not be high so that their relative deformation under the spring clip toe loads is greatly substantial. In this way, it can guarantees the rail pad maintaining in close contact with the rail despite of any vertical movements of the latter. In addition, the reason why rail pads made up of rubber or plastic is to dampen the shocks of vibration of a passing train.HuiBo Railway developed a range of high-performance elastic rail pads for stiffness requirements and various application areas-from trams through standard gauge railways to heavy haul lines, especially those for E-type rail fastening systems and SKL type rail fastening systems with material of HDPE/EVA/Rubber.

• It was also called rail plastic sleeve/plastic insert/concrete dowel/ concrete insert, which is a counter-party fastener for a sleeper screw or anchor bolt, and it is pre-imbedded into the oncrete or wooden sleeper tie, installed together with screw spikes, "guide plates and rail clips to fasten the rail tracks."

• In a set of rail fastening system, the plastic dowel can be considered as the fastening foundation, as it needs to be pre-inserted into the concrete sleeper separately before assembling the rail fastening system parts. It is used to guarantee the good connection and linkage of the rail fastening system with the concrete sleeper, with screw spikes or bolts.On the other hand, similarly as the rail pad or rail insulators, the plastic insert’s another function is to insulate the fastener parts from the ties. Therefore, the quality of this small pre-inserted part into the concrete sleeper, especially its strength and fatigue life, is of great importance to the whole rail line.

• Rail Plastic Dowels are always used in SKL fastening systems, and can be classified according to its materials needed: of PA66 or HDPE, depending on different technical specification requirements from clients.
