10kV S13 Oil Immersed Transformer

10kV S13 Oil Immersed Transformer

Key Features

Advanced Energy Efficiency

• Reduced No-Load Losses: The S13 series achieves a significant reduction in no-load losses compared to the S11 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 80% compared to the S11 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 S13 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.

• Commercial and Residential Power Distribution: The combination of efficiency and low noise makes them ideal for supplying power to commercial buildings, shopping centers, and residential complexes.
• Industrial Settings: Robust construction and the ability to handle varying loads make them suitable for industrial environments, including manufacturing plants and factories where consistent power quality is crucial.
• Rural Electrification: The S13 series can be used in remote locations where reliable power distribution infrastructure is needed to support agricultural activities and rural development.
• Substation Applications: These transformers are often used in substations as part of the step-up or step-down process, connecting power generation facilities to the distribution network.
• Renewable Energy Integration: As renewable energy sources like wind and solar become more prevalent, these transformers can play a role in integrating these intermittent energy sources into the grid by stepping up voltage levels for efficient transmission over long distances.
