E-House (Prefabricated Substation)
Sieyuan's prefabricated substation, also known as an E-House, integrates transformers, high-voltage switchgear, medium- and low-voltage switchgear, control equipment and integrated automatic protection in a movable, sealed, shock-resistant, fireproof, wind-resistant and corrosion-resistant enclosure. Design, assembly, wiring and commissioning are completed in Sieyuan's factory, and the substation is then transported to site for rapid modular assembly and installation.

Product Highlights
Smaller Footprint
Adopting a compact and integrated layout, the overall footprint is significantly reduced, resulting in higher land utilization and conservation of site resources, with an overall reduction of over 40% in land occupation.
Engineered for Fast Deployment
The construction of prefabricated substations is straightforward. The equipment is pre-assembled and integrated in the factory, requiring only the lifting of the cabin on site. This reduces civil engineering work by over 70% and installation workload by over 60%. A rapid station construction within 3-4 months can be achieved.
Faster Path to a Lower Total Cost
Sieyuan Electric possesses the capability to integrate and optimize the design of entire station equipment, offering superior system solutions to achieve savings in overall station investment. By adopting a prefabricated cabin construction model, the overall cost can be reduced by 10%
