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.
