2.4.5. The mechanical calculation of the elements of the overhead line should be carried out according to the methods described in Ch. 2.5.

2.4.6. Overhead power lines should be placed so that the supports do not block the entrances to buildings and entrances to courtyards and do not impede the movement of vehicles and pedestrians. In places where there is a danger of collision with vehicles (at the entrances to yards, near exits from roads, at the intersection of roads), the supports must be protected from collision (for example, by bollards).

2.4.7. On the overhead line supports at a height of at least 2 m from the ground after 250 m on the overhead line, the following should be installed (applied): the serial number of the support; posters showing the distances from the overhead line pole to the cable communication line (on poles installed at a distance of less than 4 m to the communication cables), the width of the security zone and the phone number of the overhead line owner.

2.4.8. When passing VLI through forests and green spaces, clearing is not required. At the same time, the distance from the wires to trees and bushes with the largest SIP sag and their largest deviation should be at least 0,3 m.

When passing overhead lines with uninsulated wires through forests and green spaces, cutting down the clearing is not necessary. At the same time, the distance from the wires with the largest sag or the largest deviation to trees and bushes should be at least 1 m.

The distance from insulated wires to green spaces should be at least 0,5 m.

2.4.9. The structures of the overhead line supports must be protected from corrosion, taking into account the requirements of 2.5.25, 2.5.26 and building codes and regulations.

2.4.10. Protection of overhead lines from electrical overloads should be carried out in accordance with the requirements of Ch. 3.1.

Machine for thinning flowers in gardens 02.05.2024

In modern agriculture, technological progress is developing aimed at increasing the efficiency of plant care processes. The innovative Florix flower thinning machine was presented in Italy, designed to optimize the harvesting stage. This tool is equipped with mobile arms, allowing it to be easily adapted to the needs of the garden. The operator can adjust the speed of the thin wires by controlling them from the tractor cab using a joystick. This approach significantly increases the efficiency of the flower thinning process, providing the possibility of individual adjustment to the specific conditions of the garden, as well as the variety and type of fruit grown in it. After testing the Florix machine for two years on various types of fruit, the results were very encouraging. Farmers such as Filiberto Montanari, who has used a Florix machine for several years, have reported a significant reduction in the time and labor required to thin flowers. ... >>

Advanced Infrared Microscope 02.05.2024

Microscopes play an important role in scientific research, allowing scientists to delve into structures and processes invisible to the eye. However, various microscopy methods have their limitations, and among them was the limitation of resolution when using the infrared range. But the latest achievements of Japanese researchers from the University of Tokyo open up new prospects for studying the microworld. Scientists from the University of Tokyo have unveiled a new microscope that will revolutionize the capabilities of infrared microscopy. This advanced instrument allows you to see the internal structures of living bacteria with amazing clarity on the nanometer scale. Typically, mid-infrared microscopes are limited by low resolution, but the latest development from Japanese researchers overcomes these limitations. According to scientists, the developed microscope allows creating images with a resolution of up to 120 nanometers, which is 30 times higher than the resolution of traditional microscopes. ... >>

Air trap for insects 01.05.2024

Agriculture is one of the key sectors of the economy, and pest control is an integral part of this process. A team of scientists from the Indian Council of Agricultural Research-Central Potato Research Institute (ICAR-CPRI), Shimla, has come up with an innovative solution to this problem - a wind-powered insect air trap. This device addresses the shortcomings of traditional pest control methods by providing real-time insect population data. The trap is powered entirely by wind energy, making it an environmentally friendly solution that requires no power. Its unique design allows monitoring of both harmful and beneficial insects, providing a complete overview of the population in any agricultural area. “By assessing target pests at the right time, we can take necessary measures to control both pests and diseases,” says Kapil ... >>

Mouse under the table 07.02.2000

Thirteen-year-old German schoolboy Moritz Pletzing invented the computer mouse for legs. It is placed under the table.

The left foot adjusts the horizontal movement of the cursor on the screen, the right foot - vertical. The "foot" mouse is connected in addition to the usual one. It is convenient because the hand does not need to be torn off the keyboard, as a result of which the speed of work on the computer is significantly increased.

The schoolchild's invention, shown at the traditional 34th exhibition of works by young scientists and inventors, will also be useful to disabled people.
