Model Meaning
Description
The S20-N×2 oil-immersed transformer is a product developed by our company through the research and application of new materials and new processes. By combining independent innovation with technology introduction and optimizing the design of the iron core and coil structure, we have achieved reduced air and load losses as well as lower noise levels. Compared with the current national standard JB/T10088-2004, the average noise level has decreased by 25%, and the product performance has reached the domestic advanced level.
Working Conditions
● Maximum ambient temperature: +40℃;
● Minimum ambient temperature: -25℃;
● Maximum monthly average relative humidity: 90% (at 20℃);
● Installation location: Indoor or outdoor.
