Recently we were selected to design and supply 2 x 2MVA packaged sub-stations for a contractor on a Government project.
We packaged our own built Mitsubishi/Leroy Somer combination generator and the transformer MV Switchgear/LV Switchgear.
The generators were installed within 65dBA @ 1mtr enclosures. The generator room and LV room were connected by corridor. Each room was 3,500mm wide to include additional walk around space.
The substations and generator were built as complete units off-site for factory testing them stripped for transport and rebuilt onsite.
