S11-M Oil-Immersed Power Transformer
S11-M series sealed oil-immersed transformers are high-efficiency, energy-saving power distribution equipment with fully sealed structure, low loss, low noise, and maintenance-free design. They are widely used in urban and rural power grids, industrial and mining enterprises, commercial buildings, and various power distribution systems.
Adopting high-quality silicon steel sheets and advanced technique, the no-load loss is greatly reduced. The fully sealed structure isolates the transformer oil from air, preventing moisture and oxidation, effectively extending service life and ensuring stable and safe operation for a long time.
This series complies with GB/T 6451, GB/T 1094, IEC 60076 and other international and domestic standards, with strong short-circuit resistance, low temperature rise, and reliable performance.
