Package/Compact SubStation (PSS/CSS)
Factory-built substation integrating MV switchgear (RMU/VCB), distribution transformer, and LV switchboard in one weather-proof kiosk for fast deployment, minimal footprint, and safer operation. Pre-wired and type-tested assemblies cut site work, speed up commissioning, and simplify maintenance.
Standard: Type-tested to IEC 62271/202 for internal-arc, ingress protection, mechanical impact, and temperature rise; MV sections per IEC 62271 series; LV equipment per applicable IEC/IS standards.
Use:Ideal for 11/22/33 kV urban networks, commercial campuses, metro/rail stations, renewable evacuation, brownfield upgrades, and tight industrial plots where uptime and space efficiency matter.

Factory-built PSS/CSS integrating RMU/VCB, transformer, and LV panel for safer 11/22/33 kV distribution with minimal
Product Description
Swastik’s Package/Compact SubStation (PSS/CSS) is a factorybuilt, typetested substation that integrates MV switchgear (RMU/VCB), a distribution transformer, and an LV switchboard inside a weatherproof, arcconsidered enclosure. Designed for rapid deployment and small footprints in urban and industrial sites, it reduces site work, accelerates commissioning, and improves safety with segregated compartments, interlocks, and IP-rated access.
* Voltage class: 11/22/33 kV primary, 415 V secondary; 50 Hz.
* Ratings: up to 2.5 MVA (project-specific).
* Safety: internal-arc compliance options, mechanical/key interlocks, visible earthing, clear mimic labeling.
* Construction: galvanized steel enclosure, segregated MV/Tx/LV bays, forced/natural ventilation as required, padmountable with trenchfriendly cable entry.
* MV section: compact RMU/VCB incomer and feeders with extensibility, earthing switches, and interlocks.
Technical Specifications
Comprehensive technical details and performance parameters
These days, the need for electrical power is growing quickly. That could be fulfilled by the power generating substations. You will find various types of power generating substations such as:
- Hydro-electric
- Atomic and
- Thermal
Based on the accessibility of various sources, substations are building at various locations. However, such locations might not be nearer to load centers. The power usage could be achieved by the load center. Therefore, it is vital to transmitting power from the substation to load center locations. Long and high transmission networks are necessary for this function.
Take note that compact substation is divided into three compartments.
- Transformer distribution compartment
- Low voltage distribution compartment
- High voltage distribution compartment
Each of them has different parts: Bear in mind that the compact substation designs are dependent on the need. For Transformer Distribution Compartment, there is:
- low voltage inlet switchgear
- low voltage outlet switchgear
- low voltage compensation switchgear
CSS is a prefabricated substation, factory-designed, tested and ready-to-install and is fully compliant with IEC 62271-202 (IEC 61330). Our compact substations are engineered to the highest possible standards for personnel safety and aesthetics, designed to help solve problems of footprint and space limitations experienced within dense urban load centers. The incomer as well as outgoing feeders are enclosed in an SF6 environment as to make the design compact. Compatible instrument for monitoring of SF6 gas pressure is mounted on the Ring Main Unit, RMU to monitor the gas pressure. SWASTIK CSS has the highest installation base in India. In distribution system, RMU is widely used as it is a complete package and only needs installation and cable connection. Everything else is within the package. This greatly reduces the commissioning time.

FAQ'S
A PSS/CSS is a factory-built, weather-proof substation that integrates MV switchgear (RMU/VCB), a distribution transformer, and an LV switchboard in one enclosure for fast deployment, smaller footprint, and safer operation.
Typical configurations support 11/22/33 kV primary at 50 Hz with secondary 415 V, and transformer ratings up to about 2.5 MVA; final voltage class, fault duty, and capacity are sized to project requirements.
Segregated MV/Tx/LV compartments, internal-arc-considered design options, IP-rated doors, mechanical/key interlocks, and clear mimic labeling reduce risk, speed isolation, and cut outage time during maintenance or faults.
Systems can include numerical relays, multifunction energy metering, fault passage indication, event logging with time-stamping, and remote monitoring/control via standard industrial protocols for SCADA/PLC.
Ideal for space-constrained urban networks, commercial campuses, metro/rail stations, industrial estates, brownfield capacity upgrades, and renewable evacuation where quick commissioning and compact footprint matter.
