Underground transformer substation serviceable from the inside. Reinforced concrete skeleton. Entrance to the transformer substation is provided through a hatch built into a waterproof, removable steel cover measuring 2.20 x 1.25m (length and width). The ventilation of the underground transformer substation is carried out through two ventilation shafts with all-aluminum covers installed in the walls. Installation or replacement of the transformer substation's instrumentation can only be carried out through a removable steel cover in the roof part of the transformer substation.
