Where is the insulated gauge tie rod installed

Insulated gauge tie rods are usually installed at the junctions of railway switches and in sections where it is necessary to improve the lateral stability of the rail and maintain gauge accuracy. Specifically, they are installed between two steel rails, which are joined by a bar at the bottom of the rail.

Junction installation: At the junction of the switch, the insulated gauge tie rod is generally installed at four corners, corresponding to four installation positions. This layout helps to provide additional support and stability in the switch area, preventing gauge changes due to the impact force of the train passing through.

Track circuit section: In some lines with track circuits, the insulated gauge tie rod not only plays the role of connecting the rail, but also isolates the electrical connection between the powered parts and the non-powered parts through the built-in insulating parts to avoid electrical failures.

Spacing Settings: The spacing Settings of insulated gauge tie rods vary according to track type, gauge, line speed, and the specific requirements of the engineering design. Generally speaking, in the straight section, the distance between the tie rods may be relatively large; In curves or areas requiring special stability enhancement, the spacing of the tie rods will be reduced accordingly.

Installation requirements:
No metal parts should be in direct contact with the insulating tie rod to ensure insulation performance.
The installation position should be located in the appropriate position of the equipment spacing (such as about 10 meters), and independent from the adjacent devices to reduce mutual interference.
The insulated gauge tie rod shall be installed near the turnout tie rod to ensure that the tie rod can be connected to it and function effectively.
