Product Overview
The new energy integrated prefabricated substation, also known as a prefabricated skid-mounted substation or E-house, is a modular, factory-preassembled power distribution solution specifically designed for renewable energy applications. It integrates high-voltage switchgear, power transformers, low-voltage switchgear, auxiliary power systems, environmental control units, and monitoring systems within a standardized containerized or skid-mounted enclosure.
This innovative solution addresses the unique requirements of wind power, photovoltaic, and energy storage projects, where rapid deployment, minimal on-site construction, and reliable performance in remote or harsh environments are essential. The prefabricated design enables substantial reduction in project timelines, civil works, and installation costs compared to traditional brick-and-mortar substations. All components are factory-assembled, wired, and tested prior to shipment, ensuring plug-and-play commissioning upon arrival at site.

Key Features
1. Skid-Mounted & Containerized Design
The substation is built on a heavy-duty steel skid frame or within standard ISO shipping container dimensions, facilitating easy transportation by truck, rail, or vessel. The structural design withstands lifting, shipping, and handling stresses without compromising internal equipment alignment or performance.
2. Comprehensive System Integration
The prefabricated enclosure integrates all necessary power distribution and control equipment including medium-voltage switchgear, power transformers up to 35kV and 10MVA or higher, low-voltage distribution panels, DC power supply systems, and UPS units. Auxiliary systems such as lighting, fire detection and suppression, HVAC units for temperature and humidity control, and cable management systems are fully pre-installed and tested.
3. Renewable Energy Optimized Design
Specifically engineered for the operational characteristics of renewable energy plants including variable load profiles, frequent start-stop cycles, and intermittent generation patterns. The transformer is available with amorphous alloy cores for ultra-low no-load losses, making it ideal for photovoltaic and wind applications with long standby periods. On-load tap changers can be incorporated for voltage regulation in unstable grid environments.
4. Weatherproof & Environmentally Robust
The enclosure is constructed from high-strength, corrosion-resistant steel with C5 or higher anti-corrosion coating, suitable for coastal, desert, and high-altitude environments. Protection ratings of IP54 or higher ensure reliable operation in dusty, rainy, and extreme temperature conditions ranging from -40°C to +50°C. Thermal insulation and forced ventilation systems maintain optimal internal operating temperatures for all equipment.
5. Factory Pre-Assembled & Pre-Tested
Complete assembly, internal wiring, and system integration are performed under controlled factory conditions. All components undergo comprehensive factory acceptance testing including dielectric tests, protection relay calibration, control system verification, and communication protocol testing. This ensures immediate operability upon site delivery.
6. Intelligent Monitoring & Remote Control
Equipped with integrated SCADA-ready monitoring systems providing real-time data acquisition of voltage, current, power, energy, temperature, humidity, and equipment status. Remote communication via fiber optic, cellular, or satellite networks enables centralized control, fault diagnostics, and predictive maintenance. The system supports standard communication protocols including IEC 61850, Modbus, and DNP3.
7. Rapid Deployment & Minimal Site Work
The prefabricated design reduces on-site installation time by up to seventy percent compared to conventional substation construction. Only foundation preparation, external cable connections, and grid interconnection are required at site. This accelerated deployment schedule is particularly valuable for renewable energy projects with tight commissioning deadlines.
8. Enhanced Personnel Safety
The enclosure design incorporates safe access, emergency egress, and interlocking systems to protect operating personnel. High-voltage compartments include arc-flash mitigation and remote racking capabilities. Fire-rated partitions, smoke detection, and automatic extinguishing systems ensure rapid response to potential fire incidents.
