Overview 

The S11 series oil-immersed transformer is a high-efficiency, energy-saving power transformer designed with a fully sealed structure, primarily used in 10kV, 50Hz power transmission and distribution systems. It is widely applicable for power and lighting supply in residential areas, commercial streets, industrial and mining enterprises, as well as rural areas. This transformer utilizes advanced technologies and materials in its design and manufacturing to achieve goals of low loss, low noise, and high efficiency, while also reducing maintenance requirements and environmental pollution.


Environmental Conditions

  • Maximum ambient temperature: +40℃

  • Minimum ambient degree: -25℃

  • altitude: < 1000m

  • Maximum monthly average relative humidity: 90%(20℃)

  • Installation location: installed in a place without fire, explosion danger, serious pollution, chemical corrosion and violent  vibration, indoor or outdoor.


Product Features

  • Reduced Losses: Utilizing premium silicon steel sheets and an optimized core structure, the S11 series dramatically lowers both no-load and load losses, manifesting in significant energy savings.

  • Minimized Noise: Through an innovative core structure and winding arrangement, coupled with advanced noise reduction technology, operational noise is substantially mitigated, ensuring a quieter environment for users.

  • Fully Sealed Design: The transformer's fully sealed corrugated oil tank design isolates it from external air, preventing oil contamination and moisture ingress, thereby improving insulation strength and extending its lifespan.

  • Enhanced Efficiency: The adoption of high-performance materials and forward-thinking design not only achieves reduced losses but also promotes efficient operation, leading to lower energy consumption and operational cost.

  • Robust Short-circuit Resistance: A specially designed winding configuration enhances the transformer's resilience against short-circuits, safeguarding the stability of the power grid and the safety of the electrical system.

  • Ease of Maintenance: The fully sealed construction diminishes the need for regular maintenance, while the thoughtful design allows for straightforward inspections and maintenance, streamlining routine upkeep and troubleshooting.
