HJ-EHouse Series Prefabricated Modular Substation
Up to 40.5kV / Fully Customizable / Turnkey Solution
The HJ-EHouse Series Prefabricated Modular Substation is a highly engineered, walk-in “Electrical House.” It is custom-designed to integrate medium voltage switchgear, low voltage MCC panels, transformers, HVAC, and smart control systems into a single, ruggedized transportable module. It serves as a plug-and-play nerve center for complex and remote power projects.
Ideal for Harsh Environments & Heavy Industries:
- ✓ Mining, Metallurgy & Oil/Gas Facilities
- ✓ Large-Scale Renewable Energy (Solar/Wind Step-up Stations)
- ✓ Data Centers (IDC) & Telecom Hubs
- ✓ Remote Infrastructure & Mobile Power Solutions
1. Drastic Reduction in Civil Works & Time
Unlike traditional brick-and-mortar substations, the HJ-EHouse is 100% factory-assembled and wired. This parallel construction methodology drastically reduces on-site civil works, weather-related delays, and labor costs, shrinking overall project deployment time by up to 50%.
2. Extreme Environmental Resilience
Engineered for the world's harshest environments. The enclosure utilizes a robust welded steel structural frame combined with fire-retardant sandwich panels. Featuring marine-grade anti-corrosion coating (up to C5-M) and advanced thermal insulation, it ensures stable operation in deserts, offshore platforms, or high-altitude regions.
3. Walk-in Design & Smart Climate Control
The spacious walk-in design provides operators with a safe, weather-protected environment for maintenance. Integrated HVAC (Heating, Ventilation, and Air Conditioning) systems maintain optimal internal temperatures and humidity, extending the lifespan of sensitive electronic components.
4. Advanced Safety & SCADA Integration
Safety is built-in. The E-House comes fully equipped with automated fire detection and suppression systems, emergency lighting, and access control. Integrated smart grid SCADA systems allow for real-time remote monitoring and unmanned operation capabilities.
Global Factory Acceptance & Turnkey Support
As a true Turnkey EPC partner, we conduct a comprehensive integrated Factory Acceptance Test (FAT) on the entire E-House system (including all internal switchgear and wiring) prior to dispatch. This guarantees that the unit is ready to energize immediately upon site positioning.
Depending on project size, the HJ-EHouse can be shipped as a single transportable skid or as multiple modular sections engineered for seamless on-site bolting and interconnection.
