Oil Immersed Transformer for Solar Farm is commonly used in utility-scale solar farms where medium voltage step-up, outdoor durability, and continuous operation are required. Its insulating oil provides both cooling and dielectric protection, making it suitable for high-capacity solar inverter stations and grid connection systems. Oil Immersed Transformer for Solar Farm can be designed with ONAN cooling, mineral oil or ester fluid, low-loss core, reinforced windings, tap changer, oil temperature indicator, pressure relief device, and customized voltage ratings.
