Specialists of branch of JSC “MOESK” - Southern Electric Grids have completed the main part of the works on the first reconstruction stage of 110 kV “Bronnitsy” substation (SS) in Ramenskiy district of Moscow region.

Renovation of substation “Bronnitsy” is made in two stages. The first stage consists in substituting of both transformers by 25 MVA by more powerful ones – 40 MVA. Subsequently, the capacity increase of the feeding center up to 126 MVA and a substitution of the obsolete energy equipment are stipulated, including 110 kV outdoor switchgear and the process control system.

During a short period of time transformer T1 - 25 MVA was dismantled, whereupon a new oil receiver was constructed and a transformer with the capacity of 40 MVA was installed to a proper location.
