It is a wire that supplies power to the train, the railway jargon "catenary", the voltage is 10,000 volts, only the electric locomotive can be used, there are two pantographs on the roof of the electric locomotive (the upper part of the locomotive can be lifted and lowered), and generally only the one behind the running direction (the train car does not have this contact equipment). After the electric locomotive introduces this electricity into the locomotive, it is divided into "three-phase electricity" by using a "splitting camera", so that the three motors in the electric locomotive can work and be pulled. Its neutral line is the track, which is passed to the electric motor by the wheels of the train.
Another point is that there are many power supply stations along the electrified railway, each power supply station is responsible for the power of a section of the railway, in the place where the power supply of the two power supply stations is handed over, the catenary should take the method of "breaking the circuit" to disconnect the electricity of the two different power stations, which is the "break" and "close" brand seen every other section next to the electrified railway, "break" means that it is about to enter another power supply section, and the locomotive is required to be powered off, and "close" means that it has entered another power supply section, and the locomotive can be closed.

Peculiarity. 1. This insulating clamp is made of hard insulating organic synthetic materials, divided into two forms: co-directional and re-directional, the insulating clamp is equipped with a circular bayonet, with less elasticity and greater hardness, and the steel bar is pressed into the bayonet, which can firmly fix the steel bar and play an isolation role.
2. At the intersection of the longitudinal and transverse steel bars, install the insulating clamp in the opposite direction, and the bayonets in the upper and lower directions of the insulating clamp (perpendicular to each other) are respectively stuck in the longitudinal and transverse steel bars; The through-length steel bar adopts the same direction insulating clamp, and the two bayonets are respectively stuck in the main reinforcement and the connecting reinforcement. The structural reinforcement between the upper and lower layers of reinforcement mesh is coated with reinforcement to ensure that no loop is formed between the two layers of reinforcement mesh. The intersection of steel bars is tied with organic synthetic materials with high strength and good durability, and it is strictly forbidden to bind or weld wires.
3. This product in a variety of industrial and civil construction, due to the use of the card seat along the parallel and vertical direction of the setting, the steel bar can be easily buckled into the card slot in it, greatly facilitating the layout of the floor steel mesh, only need to buckle the card seat on each steel bar, you can complete the mutual fastening of the steel mesh, quickly and conveniently build the steel structure, carry out concrete construction, and greatly improve the work efficiency.
Track special mainly plays the role of insulation.
The steel bars commonly used in construction are mainly steel bars, and the mechanical properties of each grade are different, and the higher the grade, the higher the mechanical performance, but the plasticity is reduced, and the bending performance is also reduced. >>>More
