DescriptionOf Insulator
Insulator is one of the core components in the railway fastener system. It is mainly used to fix the position of the rail, adjust the gauge and transmit lateral force. It also has insulation function. Its design directly affects the geometric stability, safety and maintenance efficiency of the track.
Core functions of Insulator
1. Gauge adjustment:
By replacing Insulators of different thicknesses or adjusting their installation positions, the gauge of the rail can be precisely controlled.
2. Transmission of lateral force:
Transmit the lateral force generated by the train to the sleeper or the ballast to prevent the rail from rolling over or shifting.
3. Insulation protection:
Block the current path between the rail and the sleeper to ensure the insulation safety of the electrified railway.
4. Environmental adaptability:
Through salt spray test and weather resistance test, it can adapt to harsh environments such as high cold, hot and humid, and coastal salt spray.
5. Convenient maintenance:
The insulator and the fastener system are fixed by slot or bolt, and can be replaced without disassembling the rail, which greatly shortens the maintenance time.
