The YBF-10/0.4kV series is a specialized, prefabricated "Box-type" substation engineered specifically for the renewable energy sector. It acts as the critical power conversion link in Photovoltaic (PV) plants and Wind farms, stepping up the low-voltage output (0.4kV, 0.6kV, or 0.69kV) from inverters and turbines to the 10kV/11kV medium-voltage collection grid.

Designed for high-reliability in remote, harsh environments, the YBF series combines the transformer, high-voltage switchgear, and low-voltage control systems into a single, weather-sealed enclosure that is "plug-and-play" ready for rapid site deployment.

• Optimized for Inverter Harmonics: The internal transformer and switchgear are specifically designed to handle the high-frequency harmonics and variable load cycles characteristic of solar and wind energy production.

• Corrosion-Resistant "Box" Design: The enclosure is available in high-grade Aluminum Alloy, Stainless Steel, or Glass-fiber Reinforced Cement (GRC). It features a protection rating of IP54, ensuring long-term durability against salt spray, desert sand, and intense UV radiation.

• Intelligent Thermal Management: Features a dual-layer ventilation structure with an air-interlayer to prevent solar radiation from overheating the internal components. Automated forced-air cooling is triggered by smart temperature sensors.

• Rapid Deployment & Low Civil Cost: As a completely prefabricated unit, the YBF substation requires only a simple concrete base on-site, significantly reducing construction time and labor costs compared to traditional built-in-place stations.

• Compact Footprint: The streamlined layout allows for installation in tight spaces, such as at the base of wind turbine towers or between rows of PV arrays.

1. Utility-Scale Solar Farms: Stepping up power from central or string inverters for efficient medium-voltage transmission.

2. Onshore Wind Power: Reliable voltage conversion located directly at the site of the wind turbine generator.

3. BESS (Battery Energy Storage Systems): Serving as the interface between large-scale battery banks and the utility grid.

4. Hybrid Energy Microgrids: Balancing renewable inputs with local industrial distribution.

• Integrated Smart Monitoring: Every unit can be equipped with remote telemetry systems (RTU/FTU) for real-time monitoring of transformer oil temperature, pressure, and electrical loads via SCADA.

• High Safety Standards: Includes comprehensive mechanical interlocks (five-proof) and pressure relief valves to ensure the safety of maintenance personnel in remote areas.

• Flexible Component Selection: We offer global brand integration (ABB, Schneider, Siemens) for breakers and relays, or cost-effective, high-performance domestic alternatives.

• Proven Performance: Our substations have been deployed in high-altitude, extreme cold, and high-humidity environments worldwide, with a proven service life exceeding 25 years.

Q: Can the substation handle bidirectional power flow?

A: Yes. The YBF series is designed for the modern smart grid, supporting the bidirectional flow required for energy storage and grid-tied renewable systems.

Q: Is the low-voltage side compatible with 690V wind turbine outputs?

A: Absolutely. We customize the low-voltage winding of the transformer (0.69kV) specifically for modern wind turbine and large-scale inverter requirements.

Q: How is the unit shipped?

A: The unit is shipped as a fully assembled "Complete Set." For very large capacities (above 2500kVA), we may ship in modular sections that are easily bolted together on-site.
