Dear, very happy with your question! What is the name of the pole that picks up the high-voltage line: The shelf that picks up the high-voltage line is called the cross arm in popular terms.
The installation height of the cross arm is determined according to the site situation: under normal circumstances, whether the top layer cross arm is high or low pressure and cross arm, the upper plane of the cross arm is installed at 20 cm down the rod tip during installation. The special situation is the high-voltage cross arm, because some areas are installed at the top of the pole to support the hoop (that is, the hoop is installed at the top of the pole, and a support insulator is installed on the top to support the B-phase high-voltage line, the name is different in various places, there is called the top support hoop, there is also called the bridge top hoop and so on), there are requirements for the distance between the lines, and the top cross arm is 40 cm from the top of the pole to install.
There is a kind of bridge top cross arm in the southern region, that is, a door type flat steel is welded upwards in the center of the cross arm, and the hole in the center of the flat steel is used to fix the B phase support insulator, and this cross arm is installed on the upper plane of the door iron and the rod tip is flush. When the high and low voltage pole is erected, the low voltage cross arm is installed at the meter under the high voltage cross arm, and can also be moved down or up, but the safety distance of the high and low voltage conductor and the safety distance of the conductor to the ground should be guaranteed (the lowest point of the conductor can not be less than 6 meters from the ground of the road, to prevent the vehicle from scratching) the four-wire cross arm is the low-voltage cross arm, it is usually said that the 380V power electricity, the three-wire cross arm is the high voltage cross arm, and the voltage is above 6kv. The cross arm is generally not divided into high and low pressure, except for the bridge top cross arm and the combined cross arm is a special cross arm for high pressure, the other cross arm is generally unified shape, the size and shape of the specification are exactly the same, the upper plane is generally evenly distributed four holes, the four holes are all used to install the low-pressure porcelain bottle is the low-pressure cross arm, only the side holes on both sides of the installation of the high-pressure porcelain bottle is the high-pressure cross arm.
This is a personal experience summed up in the daily construction

Summary. Hello, dear, the pole that picks the high-voltage line is called the insulating pole and also called the brake rod.
Hello, dear, the pole that picks the high-voltage line is called the insulating pole and also called the brake rod.
According to the length, the insulated operating rod can be divided into: 3 meters, 4 meters, 5 meters, 6 meters, 8 meters, and 10 meters. Insulated operating rods can be divided into the following according to the voltage level
10kv,35kv,110kv,220kv,330kv,500kv。The material of the insulated operating rod: the insulated operating rod is generally made of FRP epoxy resin rod and hand-rolled forming rod and mechanical pultrusion rod.
Both types of insulating rods have their advantages: the advantage of hand-rolled rods is that they are more tensile than those of machine-drawn rods, but their longitudinal strength is smaller than that of machine-drawn rods. The advantage of the electroscope pultrusion rod is that it is strong, but the lateral tension is smaller than that of the hand-rolled rod.

The reason why the high-voltage wire frame is strong is because of the use of nuclear stupid special design and materials, as follows
Steel rod: The high-voltage wire is usually made of high-strength steel rod, and the diameter and wall thickness of the steel rod will be determined according to the voltage level and span of the wire, so as to ensure sufficient strength and rigidity.
Insulators: The insulators used in high-voltage wire rack wires are usually made of fiberglass, which can withstand high voltage and harsh weather conditions well.
Wind resistance hanger: The high-voltage wire hanger needs to resist the blow of strong winds, so it will be equipped with a wind-resistant hanger, which can make the line more firm and stable.
Foundations and fixtures: High-voltage wire rack wires need to be installed on a solid foundation and the poles are secured to the foundation using steel or concrete fixtures to prevent tilting or shaking.
Installation and maintenance: The installation and maintenance of high-voltage wire rack lines requires professional technology and equipment to ensure the stability and safety of the line.
Therefore, the high high-voltage wire is strong because of the special design and materials, as well as the need for professional installation and maintenance.

Differences: 1. High-voltage lines: generally erected higher, with a height of about 10 meters or more, and the wires are exposed;
2. Low-voltage line: a stove hole-like erection is relatively low, with a height of about 5 meters, and there are insulators on the surface of the wires. In order to reduce the loss of power transmission over long distances, the voltage level is increased;
3. The low-voltage line is suitable for the electrical equipment to supply the world with electricity;
4. The role of high-voltage line insulation and power isolation.

Summary. Hello, I'm glad to answer for you, no, high-voltage line poles can't go along the road. Because the electricity carried by high-voltage line poles is very dangerous, if high-voltage line poles are built on highways, it will pose a threat to the safety of vehicles and pedestrians.
In addition, the construction of high-voltage line poles needs to follow certain codes and standards, and the efficiency and safety of power transmission need to be taken into account, and roads do not necessarily meet these requirements.
Hello lack of brightness, I am happy to answer for you, no, high-voltage line poles can not go along the road. Because it is judged that the power carried by high-voltage line poles is very dangerous, if the high-voltage line poles are built on the highway, it will pose a threat to the safety of vehicles and pedestrians. In addition, the construction of high-voltage line poles needs to follow certain codes and standards, and the efficiency and safety of power transmission need to be taken into account, and roads do not necessarily meet these requirements.
Legal basis: According to the "Regulations on the Protection of Electric Power Facilities" Article 10 Power Line Protection Zone: (1) Overhead Power Line Protection Zone:
The area in which the wire edge extends horizontally to the outside and is perpendicular to the ground in the two parallel planes, and the edge extension distance of the voltage wire at all levels in the general area is as follows: 1-10 kV 5 m 35-110 kV 10 m 154-330 kV 15 m 500 kV 20 m In densely populated areas such as factories and mines, towns, etc., the area of the overhead power line protection zone can be slightly smaller than the above provisions.
The bird is both feet on a wire, the potential of the high-voltage wire is very high, but the potential of the transmission line at this end is about the same as the potential at that end, the voltage added to the two ends of the wire in the transmission line is not large, so as to ensure that the electrical energy is rarely lost on the wire, with the wire as a resistance, because the wire is hundreds of kilometers or even thousands of kilometers long, and the voltage added at both ends of the wire is hundreds of volts, calculate the distance of the bird's feet, the potential difference between the bird's feet can electrocute an ant has to put a question mark, we say that the high-voltage electricity is tens of thousands of volts that is the potential of the wireWhy are people electrocuted? Standing on the iron tower, the iron tower is connected to the ground, so it is like connecting people and the ground, and the electric potential of the ground is zero. Then the potential difference between the wire and the ground is the potential of the wire, isn't it normal to electrocute people? >>>More

According to your physical fitness, it is best to do physical fitness improvement exercises about a month after you start exercising, that is, run every day, do not do other exercises first, but persevere, and it is best to stick to 30 to 45 minutes, not that you have to run all the time, you can run and walk, slowly increase the time of running, and reduce the time of walking. But be sure to do it for more than 30 minutes, and I'll give you new advice later.
