An E-House (Electrical House / Prefabricated Substation) is a factory-built, modular electrical room that integrates medium/low voltage switchgear, transformers, variable frequency drives, control systems, power quality equipment, and auxiliary systems into a standardized container or steel structure. It is fully assembled, wired, and pre-commissioned at the factory, then transported to site for rapid deployment.
Compared to traditional site-built electrical rooms, E-House offers:
Aspect | Traditional Electrical Room | E-House Solution |
Construction time | 6-12 months | 2-4 months |
Site work | Extensive civil works, wiring, testing | Foundation only + connection |
Quality control | On-site, weather-dependent | Factory-controlled, FAT included |
Relocatability | Fixed, non-movable | Fully movable and reusable |
Footprint | Large | Compact, space-saving |
E-House is widely adopted by ABB, Siemens, and other global leaders in oil & gas, mining, data centers, renewable energy, and green hydrogen projects.
With over 20 years of power electronics expertise, Sanhe Power Tech has strong capabilities in power quality, energy storage systems, and low-voltage switchgear. We deliver custom-engineered E-House solutions for diverse industrial applications.
