Underground equipment protection is a slow and expensive solution. The company is building other passive defense systems and hopes to increase air defense.
Hiding autotransformers underground to protect them from Russian shelling is expensive and time-consuming. It was reported on August 21 at Ukrainergo.
“It is not enough to just hide the transformer, it is necessary to protect all related equipment from attackers. This cannot be done for several months in all substations at the same time. Therefore, when preparing for the next winter, we mainly use other methods of protection,” explains the company.
It was noted that there are no underground substations of the 750 kV voltage class in the world, where part of the equipment operates. Ukrainergo.
No one has ever buried a 750 kV transformer underground. Yes, there are indeed underground substations of the lowest voltage class, but they were immediately planned and designed as underground … High-voltage autotransformers 330 and 750 kV are large and heavy. They produce a lot of heat during operation and can heat up to 90℃ or more. If the heat is not efficiently removed, the equipment may fail due to overheating,” the power engineers stressed.
They added that the minimum excavation depth for such a project is about 25 meters, which is comparable to digging an eight-story building underground. Such construction will not be noticed by the enemy and will last up to a year.
“The underground protection of the transformer is not necessarily a quick solution, which we need in war conditions. Especially this winter, when we have reasonable risks of new attacks on the power system from the country aggressor. We are building other passive protection systems , and also counting on increasing the density of the Ukrainian air defense,” the company summarized.
In the past it has been reported Central energy providing protective structures around the thermal power plant, which should protect the station from Russian attacks.
