10kV S11 Oil Immersed Transformer

Key Features

• Reduced No-Load Losses: The S11 series achieves a remarkable 30% reduction in no-load losses compared to the S9 series, aligning with international energy conservation standards and contributing to significant cost savings and environmental sustainability.
• Lower No-Load Current: The no-load current is reduced by 22.4% compared to the S9 series, further enhancing energy efficiency.
• High-Quality Core Materials: The core is made of high-quality cold-rolled grain-oriented silicon steel sheets, known for their superior magnetic properties. This material choice results in lower core losses and enhanced energy efficiency.
  Fully Sealed Structure: The transformer is fully sealed, preventing the ingress of moisture and contaminants, and extending the service life of the transformer. This design also eliminates the need for an oil storage cabinet, reducing maintenance requirements.
  Advanced Winding Technology: The high and low voltage windings are made of oxygen-free copper, ensuring high conductivity and durability. The low-voltage windings for 500kVA and below use a double-layer cylindrical structure, while those for 630kVA and above use a double-helix or four-helix structure. The high-voltage windings use a multi-layer cylindrical structure, enhancing the transformer's ability to withstand short-circuit forces.
  Eco-Friendly Design: The manufacturing process of the S11 series is aligned with environmental stewardship, using materials and processes that minimize environmental impact and support sustainable development goals.
