Ukrainian side has shown the reinforcement measures taken for some substations, some of which use reinforced concrete to pour a cover to enclose the main control transformer, while others use metal nets or spring nets to make a protective cover, and some are simply surrounded with sandbags around them.
These protective measures cannot withstand the large-scale bombing of Russian "Pansy"-2 suicide drones. In fact, the best way is to build all these substations underground, so that ordinary drones and missiles can't penetrate them. However, the cost is high and the construction period is long.
