The SH-M Series Amorphous Alloy Oil Immersed Transformer utilizes an advanced iron core made from an amorphous alloy of iron and boron.
This alloy is rapidly cooled in a special process to produce thin, zonal slices with a disordered atomic arrangement, offering softmagnetic properties and a narrow hysteresis loop for low magnetization work, resulting in significantly reduced excitation losses.
The transformer features a three-phase, five-column design, making it more compact than traditional three-column models.
Its core has a rectangular cross-section with a lower yoke that can open, simplifying the coil installation process.
The low-voltage winding typically uses a cylindrical structure wound with copper foil, while the high-voltage winding adopts a multi-layer cylindrical design for balanced ampere-turns and reduced flux leakage.
Both windings utilize tension devices, plastic, and press-pack technologies to enhance strength and short-circuit resistance.
Like fully sealed oil-immersed distribution transformers, it incorporates a non-lifting-core structure, vacuum drying, oil splashing, and filling technologies, along with a corrugated oil tank that eliminates the need for an oil conservator.
Notably, its no-load loss is significantly lower than conventional designs, with the SBH11 series reducing no-load loss by 75% and the SBH15 series by about 80% compared to the S9 series.
This transformer requires no oil changes under normal operation, reducing maintenance costs and extending its lifespan.
The initial investment in this energy-efficient transformer can be recouped within four years through savings on electrical energy losses, making it a cost-effective choice for modern electrical distribution needs.
