JNYB-10/0.4 Series Photovoltaic Prefabricated Step-up Substation

Product Overview

The JNYB-10/0.4 series, also known as the Photovoltaic "Huawei" (Combined) Substation, is a high-performance power solution specifically engineered to meet the rigorous demands of the global solar energy market. As clean energy production accelerates, this substation serves as a critical link, stepping up the low-voltage output from solar inverters to 10kV or 35kV for efficient grid integration.

By integrating the transformer, high-voltage load switches, and fuses into a single, fully-sealed, and insulated unit, JNCN Power provides a compact, "plug-and-play" solution that optimizes both land use and installation speed.

Core Advantages & Engineering Excellence

Ultra-Compact & Lightweight Design: Engineered with high power density, our substation occupies a significantly smaller footprint than traditional modular designs, making it ideal for large-scale solar farms and distributed rooftop projects.
Advanced Surface Protection: The enclosure undergoes a specialized multi-stage treatment—including shot blasting, pickling, and phosphatizing—before receiving a high-durability primer and UV-resistant topcoat. This ensures the unit withstands extreme weathering, scratching, and UV degradation for over 25 years.
Superior Insulation & Thermal Management: Utilizing high-grade transformer insulation liquid as both a dielectric and heat dissipation medium, the unit maintains stable core temperatures even during peak solar generation hours.
Hermetically Sealed Reliability: The fully-sealed structure protects internal components from moisture, dust, and corrosive salt mist, making it suitable for coastal, desert, and high-altitude environments.
Flexible Protection Schemes: Equipped with high-voltage current-limiting fuses and specialized load switches, providing comprehensive protection against overloads and short circuits.
