Special 150-meter towers-diverters equipped with external lightning protection components will be installed for the cosmodrome Vostochny in the Amur region. The corresponding message appeared on the second of September on the website of the Federal Agency for Special Construction. The installation was made by the Main Directorate №4 of the Special Construction of Russia.
According to the website, the installation of lower sections of the second tower on the concrete foundation is being carried out now. This will ensure the height of the tower- lightning rod of 40 meters. After that, a 250-ton crane will be used to increase the height of the tower to another 40-50 meters.

To increase the height, a unique jack-up crane, fixed on the already finished part of the lightning rod tower, will be used. The next metal sections of the tower will be raised from it. With the installation of the next sections "the creeping crane" will rise to new heights on the already installed parts. The agency's website also reports that the work is complicated by the highest requirements to the connection of elements, as well as the wind load on vertical constructions. In this regard, installation of lightning protection components at this facility will be performed by the installers and welders of high qualification.
Unique lightning protection and grounding system on the comodrome Vostochny was designed taking into account the peculiarities of the climatic conditions of the region and the characteristics of the objects' complex. It consists of freestanding masts of different heights. At the moment, eight lightning rods 50 meters high and three lightning rods 18 meters high are already installed.
Design and installation of construction of lightning rods should always be carried out taking into account the wind load, regardless of the type of object for which lightning protection is intended. Read more about the wind load on lightning rods in our article on a separate page.
