Product Description

Product Description

S11-250/10 oil-immersed distribution transformer

  

High-Efficiency Power Transformer

  Our premium power transformer delivers stable voltage conversion for industrial, commercial and residential use. With low energy loss, robust core design and corrosion-resistant casing, it ensures reliable operation even in harsh environments.

  Compact size, easy installation and compliance with international safety standards make it an ideal choice for power distribution systems.

 

High-Insulation Power Transformer

 

     This industrial transformer excels in top-tier insulation performance, crafted with advanced nano-insulation materials and vacuum-sealed technology.

    It effectively blocks current leakage and withstands extreme voltage fluctuations, ensuring zero breakdown risks even in long-term heavy-load operations.

    Compliant with CE and UL standards, it's a safe, durable solution for critical power supply systems.

 

Excellent Voltage Regulation and Transformation

    Our oil-immersed transformer features excellent voltage regulation and transformation performance for stable power supply. With a precise winding turn ratio, it achieves accurate voltage conversion matching grid requirements.

    Equipped with a tap changer (±5%/±2×2.5% range), it fine-tunes output voltage to adapt to grid fluctuations. Boasting low voltage regulation rate (≤±2.5%), it ensures consistent power quality for industrial and power grid applications, delivering reliable and efficient voltage transformation.

 

Outstanding Low-loss Performance

    This oil-immersed transformer is engineered for outstanding low-loss performance, slashing energy consumption significantly. It features an optimized core and winding design that minimizes no-load and load losses, with high operational efficiency (≥98.5%).

    The low loss design reduces heat generation, lowering cooling demands and extending the transformer's service life. Ideal for long-term continuous operation in industrial and power grid applications, it delivers cost-effective and eco-friendly power transformation.
