Power Generation Prefabricated Compact Secondary Substations 10kV 15kV

The substation complies with international and national standards, offering high integration, compact footprint, reliable performance, and simple on-site installation. Its modular design allows positioning closer to load centers, reducing cable losses and improving power supply quality. The enclosure is fully sealed, corrosion-resistant, and equipped with temperature-controlled forced ventilation and automatic thermal management.

Key Features

• Integrated design ：Combines MV switchgear, transformer, and LV distribution equipment in one factory-wired, pre-commissioned enclosure, minimizing site work
• Compact footprint： Requires less land than conventional civil substations and can be placed closer to load centers
• Flexible relocation： Unitized transportable design allows reuse at different sites
• Supplementary switchgear options：Available with ABB air-insulated or gas-insulated MV secondary switchgear for enhanced reliability
• Transformer flexibility：Supports both oil-immersed and dry-type transformers to suit application requirements
• Robust enclosure ：Corrosion-resistant, moisture-proof, anti-rust steel enclosure with thermal management, rated IP23 (HV/LV compartments) and IP55 (oil transformer) / IP65 (dry transformer)
• Full secondary integration ：Equipped with control, protection, live-line indication, metering, and lighting systems

Technical Parameters

• Wind farm auxiliary power systems
• Solar photovoltaic plant collection and distribution
• Thermal and hydro power plant auxiliary power supply
• Secondary distribution networks in industrial parks, residential communities, and commercial complexes
• Remote or temporary power supply requiring rapid deployment
