Product Introduction：

S20-M-10 series 10kV full sealed oil-immersed distribution transformer is the mainstream standard model in the current power grid construction and urban and rural distribution network upgrading. Based on S13 series, this series greatly reduces the no-load and load losses through the comprehensive improvement of the core materials, the optimised design of the electromagnetic and temperature field and the refined control of the manufacturing process. It increases energy efficiency by about 15% compared to the S13 series, which results in considerable savings on the electricity bill for its entire life cycle and a short investment return period. Full sealed corrugated oil tank structure without oil conservator to separate the insulating oil from air and moisture , to delay the ageing of the insulation , to achieve maintenance free operation and maintenance , to greatly reduce the total investment of the user in the whole life cycle . At the same time, the product has low noise, strong short-circuit withstand capability, wide adaptability and other core advantages. It flexibly adapts to the power distribution needs of various scenarios including urban and rural distribution networks, industrial enterprises, commercial buildings and new energy power plants. At present, it is the best mainstream choice for distribution network construction, with a balance between cost and energy efficiency.

Technical Parameter：

Application scenarios: 

The excellent energy-saving performance, high reliability and maintenance-free advantages of S20-M-10 series transformers make it a mainstream standard model in current power grid construction and are widely used in the following scenarios: 

1. Urban and Rural Distribution Network Construction and Renovation As the main energy-saving model of power grid companies for distribution network construction, it is widely used in new construction, reconstruction and upgrading projects of urban and rural distribution networks, meeting the standard construction requirements of power grid. 

2. High-end commercial buildings in power distribution networks of urban core areas: Provides power distribution security for high-end office buildings, large shopping malls, star-rated hotels, hospitals, schools, and other buildings in urban core areas. The low noise and high reliability are appropriate for the sensitive environment of urban core areas. 

3. Large industrial parks and manufacturing enterprises It realises the centralised power distribution security for industrial parks, large manufacturing enterprise production bases and industrial parks. Good energy saving performance can significantly reduce the electricity cost of enterprises. High short-circuit resistance Suitable for the impact requirements of industrial loads. 

4. Data centre and communication base station: Ensure the safety and stability of power distribution security of core equipment of data centre and communication base station. The high reliability and low loss characteristics are suitable to the 24-hour continuous operation requirements of data centres. It is the core power supply equipment of new infrastructure projects. 

5. New energy power stations and energy storage facilities: It is the core power distribution and step-up equipment for photovoltaic, wind power generation and energy storage power stations, which is adapted to the fluctuation characteristics of new energy power generation, ensuring stable grid connection of power and efficient operation of energy storage systems. 

6. Transportation infrastructure facilities: Provides security of power distribution in airports, railway stations, subway stations, highways and other transportation infrastructure. High reliability and maintenance free features are suitable for the unattended operation and maintenance requirement of transportation infrastructure.
