Compact Sub Station

The Compact Sub Station (CSS) also called Packaged Sub Station (PSS).

The Compact Sub Station (CSS) is a compact enclosure that comprises MV switchgear, a transformer, LV switchboard along with interconnections and auxiliary equipment for the transformation of energy from medium to low voltage system which is located in three separate compartments segregated from each other by means of partitions for the safety of personnel. Each compartment is fitted with lockable doors to access to operate or maintain the equipment to ensure maximum security. Factory assembled for complete substation assembly to reduce installation time and cost on site. All of the equipment is high quality and is tested as a single unit.

Medium Voltage Switchgears
The MV Switchgear compartment is Equipped with Compact Ring Main Unit (RMU) & Vacuum Circuit Breaker (VCB).

Transformer
Dry and oil type transformer can be installed inside the transformer compartment , the transformer rating for oil type transformer is up to 2500 KVA. The transformer compartment is designed to allow smooth flow of air and natural cooling to meet the temperature rise requirement as per standard.

Switchboard LV
LV Switchboard compartment consists of Low Voltage distribution board fed from the transformer secondary side. The LV Switchboard can be designed on customer’s requirement. The Panel can take different types of switching devices Breaker (ACB or MCCB) or fuse switches.
