The SBH21-10kV series oil-immersed amorphous alloy distribution transformer represents a significant technological leap forward in reducing power grid distribution losses and mitigation of atmospheric pollution. Engineered as a highly efficient, new-type green distribution solution, this transformer utilizes an iron core constructed from premium iron-based amorphous alloy ribbons. Compared to traditional silicon steel core transformers, the SBH21 series achieves an extraordinary reduction of approximately 80% in standing no-load losses, providing magnificent energy-saving benefits across standard electrical utility grids.
The core material features high saturation magnetic induction, low exciting current, and excellent thermal stability, derived from a rapid cooling production process that leaves metal atoms in a disordered, non-crystalline state. Structurally, the SBH21-10kV transformer adopts a reliable single-frame or three-phase five-column wound core design with a tightly clamped, formed frame structure. The low-voltage windings are engineered as copper foil structures, which drastically lower structural loss, optimize thermal dispersion, and significantly bolster short-circuit resistance. It has been fully certified as a national energy-saving product and is highly recommended for modern ecological grid projects.
