Product Classification
Classified by structural characteristics
Fully sealed oil immersed transformer: The S13 (22) - M transformer adopts a fully sealed corrugated sheet oil tank design, eliminating the traditional oil storage tank. The expansion and contraction of corrugated sheets are used to compensate for changes in oil volume, isolating the interior of the transformer from the atmosphere, thereby preventing oil degradation and insulation moisture, and improving operational reliability.
Classified by performance level
Energy saving transformer: The S13 (22) - M transformer uses high-quality high permeability oriented silicon steel sheets as the iron core. After optimized design, the no-load loss is reduced by an average of 45% compared to the national standard, and the load loss is reduced by an average of 35%. It belongs to the new generation of energy-saving products.
Classified by application scenario
Distribution Transformer: S13 (22) - M Transformer is suitable for power plants (stations), substations (distribution stations), industrial, commercial, building and other fields of distribution systems, providing stable and reliable power supply for various users.
Classified by series affiliation
S13-M series transformer: S13 (22) - M transformer can be regarded as a specific model or upgraded version of the S13-M series transformer. This series of transformers has strong overload capacity, short-circuit and overvoltage resistance, as well as energy-saving, environmental protection, reliable long-term service life and other characteristics.
