Gnee Steel (Tianjin) Co., Ltd. is one of the most reliable manufacturers and suppliers of insulated rail gauge rod in China, also supports customized service with low price. Please feel free to buy cheap insulated rail gauge rod made in China here from our factory.
For some railway lines with track electro-circuits, the insulated parts must be designed in the rod to separate two rails. Therefore, railway engineers invented the insulated gauge tie rods. The largest effect of the insulated gauge rod is to make its middle part get the insulation in order to achieve the purpose of track insulation. To play a role in blocking the circuit between the two rails, the insulating materials are with high insulation nylon resistance materials with standard size, high lateral stiffness, good insulation properties, tensile strength and other advantages.
Ambient temperature
The insulated gauge rod is suitable for the ambient temperature -40℃~60℃.

The materials of track insulation used for the rail gauge rod include:
1. The winding insulation glass pipe
2. The pultruded fiberglass pipe
The insulated rail gauge rods include the following types:
1. The threaded connection
2. The casing connection
3. The folding connection
The insulated gauge tie rod is a special tool for railway rail drilling. It is applicable to a wide range including the maintenance operations. When the card is installed, the installation is accurate and the detachment is quick and fast, which can guarantee the safety of the train driving. It can be processed by the high-speed alloy steel hollow drill. The drilling is short in time with the features of high precision and long service life. The manufacturing machine adopts the spindle cooling structure equipped with high-pressure cooling pot.
