The Compact Sub Station (CSS) also known as Packaged Sub Station (PSS).

The Compact Sub Station (CSS) is a compact enclosure consisting of MV switchgear, a transformer, LV switchboard along with interconnections and auxiliary equipment to transform energy from medium to low voltage system located in three separate compartments which are segregated from each other by means of partitions in order to ensure personnel safety. Accessibility to operate or maintain the equipment is through lockable doors provided for each compartment to maximise security. Assembly of the complete substation is factory ready to minimise site installation time and cost. All equipment is of high quality and tested as a complete unit.
