Compact Substation

Electrical Overhead Corporation is a trusted manufacturer and supplier of Compact Substation in India, offering reliable and space-saving power distribution solutions for industrial, commercial, and infrastructure projects. Compact Substations (CSS) are factory-assembled units that integrate high-voltage switchgear, distribution transformers, and low-voltage switchgear into a single compact enclosure, ensuring safe and efficient power distribution.


Designed to meet modern electrical requirements, our compact substations provide superior performance, enhanced safety, and easy installation while minimizing space requirements. These substations are widely used in industrial plants, residential developments, commercial complexes, renewable energy projects, and utility networks across India.


A compact substation plays a vital role in electrical generation, transmission, and distribution systems by transforming voltage levels from high to low or vice versa. It ensures efficient power transfer from generating stations to end users through a reliable and secure power distribution network.


What is a Compact Substation?


A Compact Substation (CSS) is a prefabricated power distribution unit that combines:


  • High Voltage (HV) Switchgear
  • Distribution Transformer
  • Low Voltage (LV) Distribution Panel

into a single enclosed structure. This integrated design reduces installation time, saves space, and enhances operational safety compared to conventional substations.


Compact substations are manufactured according to national and international standards and are tested to ensure long-term reliability under demanding operating conditions.
