TSTY Wind Power Compact Substation

TSTY Wind Power Compact Substation (prefabricated substation dedicated for wind power) is an HV/LV prefabricated substation integrating high‑voltage switchgear, step‑up transformer, protective fuses, low‑voltage switchgear, and auxiliary control systems. Specifically designed for wind turbine systems, it steps up the low voltage AC output (0.69kV or 1.14kV) from the wind generator to 10kV or 35kV, delivering power to the grid via medium voltage lines. The substation features a compact footprint, external radiators for better heat dissipation, and advanced transformer technology for high reliability. The transformer oil serves as the insulating medium for the 10kV/35kV high‑voltage components, significantly reducing required clearance distances, enabling miniaturization and high protection.

Fully Sealed, High Protection
The enclosure is fully sealed, isolating the transformer oil from the atmosphere and greatly reducing oxidation and moisture ingress, thereby improving system stability and reliability. The HV/LV compartments achieve IP54 protection, while the transformer itself reaches IP68, capable of long‑term submersion, making it resistant to rain, salt spray, and sandstorms.
Efficient Cooling for Extreme Climates
External fin‑type radiators are easy to disassemble and maintain. Natural air cooling combined with forced ventilation ensures stable operation from -40°C to +55°C, suitable for high‑altitude, low‑temperature, high‑humidity, and coastal environments common in wind power.
Strong Anti‑Corrosion & UV Resistance
The enclosure is treated with a special shot‑blasting process and coated with salt‑spray and UV‑resistant paint. It withstands coastal salt‑fog corrosion, intense sunlight, and sand erosion in desert areas.
Intelligent Monitoring & Remote Operation
The transformer tank can be equipped with pressure and temperature gauges with communication interfaces. The load break switch can include a limit switch. Via RS485, Ethernet, or wireless modules, key parameters such as oil temperature, oil pressure, and load status can be remotely monitored, alarmed, and operated, supporting unattended wind farms.
High‑Performance LV Distribution
The low‑voltage side uses modern intelligent circuit breakers and moulded case switches with high breaking capacity and superior protection. It can integrate energy metering, surge protection, and redundant power supplies for auxiliary loads (e.g., tower lighting, communication equipment).

TSTY Wind Power Compact Substation is widely used in:

Onshore Centralized Wind Farms – Installed at the tower base or on a nearby concrete foundation for each turbine. Single‑turbine units or multiple units in parallel, stepping up power to 35kV collector lines.
Distributed Wind Power Projects – Suitable for wind turbines located in industrial parks, agricultural facilities, or remote villages, connecting directly to 10kV or 35kV distribution grids.
High‑Altitude & Low‑Temperature Sites – Equipped with special low‑temperature oil and reinforced seals, operating reliably at altitudes up to 4500m and temperatures as low as -40°C. Proven in Qinghai‑Tibet Plateau and Inner Mongolia wind farms.
Coastal & Offshore Wind Power – C5‑M anti‑corrosion coating and IP68 transformer enclosure allow temporary immersion, ideal for tidal flats, intertidal zones, and onshore collector stations for offshore wind farms.
Old Wind Farm Repowering – Compact design facilitates replacement of traditional discrete equipment, reducing downtime and increasing energy yield.

TSTY Wind Power Compact Substation is CE, IEC, UL, ISO, SASO‑certified, complying with IEC 60076, IEEE C57, and GB/T 17467 standards. With a CNAS‑accredited laboratory and over 30 years of power equipment manufacturing experience, TSTY has delivered products to more than 80 countries, providing safe, efficient, and intelligent step‑up and grid‑connection solutions for wind projects.
