Features / Highlights

1. Flagship product with high energy saving: S22-M-10 reaches the highest performance level of oil-immersed distribution transformers so far.

2. Overall Upgrade of Core Materials, Ultimate Energy Saving Use of ultra high permeability cold rolled grain oriented silicon steel sheets of 0.23mm and below thickness, 5-stage step-stack process and optimised winding and insulation design, no-load loss is reduced by about 20% compared to S20 series and by about 60% compared to traditional S11 series. The savings in electricity over the entire life of the equipment are many times the purchase cost of the equipment, giving a return on investment in 2-3 years. The lowest operating cost in the industry over the complete lifecycle.

3. Fully Sealed Double Corrugated Structure, No Maintenance During Lifecycle: Completely isolated from air and moisture by a reinforced fully sealed double corrugated tank structure, combined with ultra-resistant ageing seals and deeply refined insulating oil. It can slow down the ageing rate of the insulating oil by more than 80% and the designed service life can be more than 40 years. No core lifting, oil changes or maintenance are needed throughout the entire life cycle, only periodic visual inspections, drastically reducing the user’s total life cycle investment.

4. Ultra-quiet operation, suitable for the most sensitive environments ultra-high permeability magnetic core, optimised lamination process and structural design can achieve ultra-quiet operation, perfectly suitable for sensitive environments with extremely high noise requirements, such as hospitals, schools, high-end communities, data centres and communication hubs.

5. Excellent insulation reliability, strong short-circuit withstand ability: new insulation materials, optimised winding structure and refined manufacturing processes make the partial discharge far below the industry standard and greatly prolong the insulation life. It has a higher short-circuit withstand capability, capable of withstanding short-circuit impacts far beyond industry standards, ensuring safe and stable operation of the equipment under extreme conditions, with industry-leading trouble-free operation time throughout its entire lifecycle.

6. One to one customised service, perfect matching for all scenes. We have one to one customised service, can be customised all parameters, such as capacity, voltage, frequency, voltage regulation level, on-load tap changer, high temperature type, low temperature type, corrosion-resistant type, low noise type. Applicable to pole-mounted, platform-mounted, box-type, indoor distribution rooms and unattended stations, meet the demanding requirements of high-end distribution network projects, data centres, high-end commercial projects, large industrial parks and new energy power plants.

Product overview

The S22-M-10 series 10kV fully sealed oil-immersed distribution transformer is the highest energy-saving level and manufacturing process of oil-immersed distribution transformer at present, which leads the development direction of the industry. This series is based on the S20 series with comprehensive upgrades of core materials, multi-physics field collaborative optimisation design and refined manufacturing process control, so that the no-load loss and load loss of the transformer are the lowest in the industry, and the energy-saving performance is the best in the industry, and the total life cycle cost is the lowest. The product adopts a fully sealed double-corrugated oil tank structure, new aging-resistant seals and deeply refined insulating oil to completely isolate it from air and moisture, achieving zero-maintenance operation throughout the entire life cycle and greatly reducing the user's total life cycle investment. Meanwhile, the product also has the core advantages of ultra-quiet operation, superior short-circuit withstand capability, ultra-high insulation reliability and customised adaptability of all scenarios. It can fully meet the arduous use requirements of various high-end scenarios such as high-end commercial buildings, large industrial parks, data centres, communication base stations and newly-built high-standard distribution network projects, and is the preferred flagship model for high-end distribution network projects.
