S11 Oil Filled High Voltage Transformer

S11 Electric Oil-Immersed Power Transformer

Key Features of S11 Oil-Immersed Transformers

Oil-Immersed Design

• Enhanced Cooling Efficiency: The oil-immersed design provides superior cooling capabilities, ensuring that the transformer operates at optimal temperatures. This is crucial for maintaining high efficiency and extending the service life of the transformer.
• Thermal Stability: The transformer oil acts as an effective coolant and insulator, absorbing and dissipating heat generated during operation. This thermal stability reduces the risk of overheating and ensures consistent performance under varying load conditions.
• Moisture Protection: The fully sealed design prevents the ingress of moisture and contaminants, protecting the internal components and extending the life of the transformer. This is particularly important in harsh environmental conditions.

Energy Efficiency

• Reduced No-Load Losses: The S11 series achieves a 30% reduction in no-load losses compared to the S9 series, aligning with global energy conservation standards. This significant improvement in energy efficiency leads to substantial cost savings and a reduced environmental footprint.
• 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.

Structural Integrity

• Robust Construction: The S11 series is designed with a robust structure and optimized oil circulation, ensuring exceptional structural strength and reduced weight. The enhanced oil flow design facilitates superior heat dissipation, reducing energy loss and maintaining operational efficiency.
• 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.

Environmental Compliance

• 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.
• Regulatory Adherence: Manufactured in strict compliance with IEC 60076 and GB1094 standards, ensuring that each transformer meets the stringent criteria set by the industry's leading standards for safety, reliability, and performance.
