Rail Insulators, Rubber Pads and Dowel

Zhongbo

Zhongbo offers E-type rail insulators and guide plates for the SKL rail fastening and Nabla fastening systems.

The material we use for rail insulators is PA66, with the colours white, dark brown and black. Our rail nylon insulator is used to adjust rail gauge and insulate the rail from ties and clips.

The raid pad prevents rail-sleeper abrasion and the sleeper being crushed under the rail foot. Rubber rail pads are normally designed to a specified load-deflection characteristic. The initial stiffness of the rail pad is designed to be low so that that their deformations under the springs toe loads is quite substantial.

This ensures that the rail pad remains in intimate contact with the rail despite any vertical movements of the latter. When the wheel is over the pad, the latter’s stiffness must be high to prevent large movements, which can result in the metal spring becoming loose. The rail pad offers:

  • Noise suppression
  • Improved passenger comfort
  • Extended track life
  • Extended ballast life

The rail plastic sleeve is pressed in concrete sleepers and assembled with sleeper screws, guide plates and rail clips to fix the rail. Our rail plastic sleeve is made using either HDPE or PA66 and the product colours include white, black and dark brown.
