The YBF-12 Step-up Box Substation is a fully integrated, factory-assembled solution designed for solar photovoltaic power plants. It combines a high-efficiency oil-immersed transformer, HV and LV switchgear, and auxiliary systems in a single weatherproof enclosure. Rated primary voltage up to 12kV and secondary voltage 0.4kV, it steps up generator output for grid connection. The substation features a robust steel housing with IP54 protection, corrosion-resistant coating, and natural cooling. Integrated protection relays, surge arresters, and a smart control panel ensure reliable operation and remote monitoring. Typical capacity ranges from 200kVA to 2000kVA, catering to medium and large solar installations. Easy to transport, install, and maintain, the YBF-12 is ideal for utility-scale solar farms, commercial rooftops, and distributed generation projects.
