insulator railway, also known as fishtail plate, is a kind of railway accessories and a key component of railway switches, so the necessity of insulator railway is obvious. If there is a problem in insulator railway, it will inevitably endanger the safety factor of railway line. Therefore, when the railway switch is in normal operation, it is necessary to check the operation time of the straightener and carry out maintenance. If the hair straightener is found to be damaged, it must be repaired or replaced.

The key of insulator railway can be divided into general insulator railway, insulator layer insulator railway, non-standard insulator railway, special type insulator railway and so on. Among them, the general insulator railway is a railway rail made of Q235 steel, which can be used in many types of railway tracks. The production process and raw materials of the insulating layer insulator railway shall be carried out in accordance with the product standards of the insulating layer materials, in addition, the compressive strength of the insulating layer insulator railway shall be ensured. Heterogeneous insulator railway is generally different from non-standard insulator railway.

insulator railway is the key component of the urban track, which is closely connected, on the one hand, it guarantees the safety of the train, on the other hand, it guarantees the safety of the passers-by. insulator railway is generally made of metal material, which is a minefield for the safety of railway freight. Two-track insulator railway with four and six holes is generally used for tracks of different lengths and net weights in applications. Because different slides have certain regulations on the quality of insulator railway, apart from the difference between the two holes, the net weight of insulator railway is also different.
