Oil Immersed Distribution Transformer

Product Description: S11 and S13 Series Oil Immersed Transformer

S11 Series Transformer

• Energy Efficiency: The core is made of high-quality cold-rolled grain-oriented silicon steel sheets with a multi-level step-type full-bevel joint structure. This design reduces no-load losses by 30% compared to the S9 series.
• Structural Design: The transformer features a simple and reasonable structure, ensuring good strength, light weight, unobstructed oil channels, and efficient heat dissipation.
• Environmental Compliance: The S11 series complies with national industrial policies and international standards, including IEC 60076 and GB1094, ensuring safety and reliability.
• Performance: The overall performance indicators of the S11 series have reached the world's advanced level, making it a leading choice for modern power distribution systems.

S13 Series Transformer

• Advanced Core Material: The core is made of the highest quality cold-rolled grain-oriented silicon steel sheets, with a more stringent manufacturing process that enhances performance.
• Energy Efficiency: The S13 series offers a 25% reduction in no-load losses and an 80% reduction in no-load current compared to the S11 series.
• Noise Reduction: The design reduces noise levels by 5-10 dB, making it suitable for urban and residential areas.
• Environmental Protection: The fully sealed corrugated oil tank structure prevents air and moisture from contacting the transformer oil, reducing oil aging and extending the service life of the transformer.

Applications

• Power Plants: Efficient energy generation and distribution.
• Electrical Grids: Reliable transmission of electricity.
• Petrochemicals and Metallurgy: Stable power supply for industrial processes.
• Industrial and Mining Enterprises: Continuous and stable power supply for manufacturing and processing units.
• Urban Infrastructure: Sustainable power solutions for airports, subways, docks, and residential areas.
