20 kV Single-Phase Oil-Immersed Distribution Transformer

The single-phase oil-immersed distribution transformer with stacked core features compact structure, attractive appearance, small size, low temperature rise and noise, strong overload capacity, excellent electrical and mechanical performance, and reliable operation. Our energy-saving products are developed through research and application of new materials and processes, combining independent innovation with technology introduction. By optimizing the core and coil structure design, we achieve reduced no-load loss and noise. The products are professionally developed using advanced domestic and international technologies and equipment. The core uses high-performance cold-rolled grain-oriented silicon steel, with fully automatic robotic stacking machines, minimal shearing burrs, and low stacking factor, effectively reducing no-load loss, no-load current, and noise. No-load loss is reduced by 5% to 10% compared to manual stacking.
