The oil-immersed wind power transformer is specifically designed for harsh operating environments in wind farms. It is typically installed inside the wind turbine tower or on the base platform. Its primary function is to step up the low voltage generated by the wind turbine (e.g., 0.69 kV or 35 kV) to a higher grid transmission voltage (e.g., 35 kV or 110 kV), thereby reducing energy loss during power transmission.

Oil-immersed Wind Power Transformer Features

Environmental Adaptability: Excellent weather resistance, designed to withstand harsh conditions including high humidity, salt spray (for offshore wind power), windblown sand, and extreme temperature variations.
High Short-Circuit Withstand Capability: Utilizes high-strength electromagnetic wire and specialized winding techniques to endure frequent load fluctuations and grid disturbances in wind power systems.
Compact Design: Features a space-saving structure with a relatively small footprint to meet strict installation constraints within wind turbine towers or on platform bases.
Superior Sealing Performance: Hermetically sealed construction or equipped with pressure relief devices to prevent moisture and air ingress, delay insulation aging, and extend maintenance-free operation periods.
Outstanding Overload Capacity: Designed to accommodate short-term overloads during periods of high wind energy availability, maximizing energy utilization efficiency.
Low Loss Characteristics: Manufactured with high-quality silicon steel cores and advanced engineering to minimize no-load and load losses, complying with energy efficiency and environmental requirements.
