Our Services / Compact Substation (CSS) Installation

Compact Substation (CSS) Installation

As industrial space becomes premium, Compact Secondary Substations (CSS) offer a powerful, space-saving solution. We supply and install these factory-assembled units that integrate High Voltage switchgear, Transformers, and Low Voltage distribution into a single, safety-compliant enclosure.

Infrastructure Setup

Site Preparation & Plinth

We verify soil bearing capacity and construct a specialized concrete plinth with precise cutouts for HV and LV cable entry. This ensures the heavy CSS unit sits level and cables can be routed without stress.

Unit Placement & Assembly

Utilizing heavy-duty cranes, we position the CSS (often weighing 5-10 tons) safely. Since these are pre-fabricated, site work is minimized to assembly and connection, reducing project timelines significantly.

System Integration

HT & LT Terminations

We perform the critical connections—terminating the incoming 11kV/33kV supply to the RMU section and connecting the heavy-duty LV busbars/cables to your main distribution panel.

Safety Interlocks & Earthing

We connect the CSS body, transformer neutral, and lightning arresters to a dedicated earth grid. We also verify all mechanical interlocks to ensure the unit cannot be opened while live, ensuring operator safety.
