Features/Highlights:

1.A mainstream standard configuration for power grids, a core energy-saving mainstay model for distribution network energy upgrading. 

2. Better core materials, the best energy efficiency in the industry: Made of high quality cold rolled grain oriented silicon steel sheet, optimised lamination process and winding design, no load loss is about 15% lower than S13 series and about 40% lower than traditional S11 series. Substantial savings in electricity costs over the entire lifecycle, investment returns recoverable in 3-5 years. 

3. Full sealing, Maintenance-free, good lifecycle cost: The fully sealed corrugated oil tank structure is adopted, no need for oil conservator, complete separation of air and moisture, greatly delays the ageing of insulating oil, designed service life is more than 30 years. Operation and maintenance costs are greatly reduced without the need for routine core lifting or oil changes, only periodic inspections. 

4. Ultra-quiet operation, ideal for sensitive surroundings: The high permeability magnetic core and optimised structural design fully satisfy the noise requirements of sensitive surroundings, such as residential areas, hospitals, schools, and high-end commercial buildings. 

5. Superior Short-Circuit Resistance and High Reliability: The optimised winding structure, high-strength insulation materials and advanced manufacturing processes provide superior short-circuit resistance and ensure reliable and stable operation even under extreme conditions. 

6. Suitable for All Scenarios, Flexible and Convenient Installation Customisable parameters: capacity, voltage, frequency, voltage regulation levels, high altitude type, low temperature type. It is suitable for pole-mounted, platform-mounted, box-type, indoor distribution rooms, unmanned stations and other installation methods. It is widely used in urban and rural power distribution networks, high-end commercial, industrial park, data centre and new energy power plants. 

Product Summary

S20-M-10 series 10kV fully sealed oil-immersed distribution transformer is a mainstream standard model for the current power grid construction and urban and rural power distribution network upgrading. This product series is based on the S13 series and further reduces transformer no-load and load losses through comprehensive upgrades of core materials, optimised electromagnetic and temperature field design and refined manufacturing process control. The S14 series is about 15% more energy efficient than the S13 series. This translates into significant savings in electricity costs over the entire product life cycle. It is the best mainstream choice for the present distribution network construction which is balance of cost-effectiveness and energy efficiency, with a short payback period. The product adopts a fully sealed corrugated oil tank structure, which can not only eliminate the oil conservator, but also isolate the insulating oil from air and moisture, delay the ageing of insulation, and realise maintenance-free operation and maintenance, greatly reducing the user’s total life cycle investment. The product also has the core advantages of low noise, strong short-circuit withstand ability and wide adaptability, which can be flexibly used for the power distribution of various scenarios such as urban and rural distribution network, industrial enterprise, commercial building and new energy power plant. It is the mainstream model for energy-saving designated for the distribution network construction of power grid companies.
