20kV Oil-immersed Distribution Transformer

Product Description

The 20kV oil-immersed distribution transformer features a compact structure, small size, strong overload capacity, excellent electrical and mechanical performance, and reliable operation. The core is made of high-performance cold-rolled grain-oriented silicon steel sheets, processed by fully automatic robotic stacking machines, resulting in small shearing burrs and low stacking factor, effectively reducing no-load loss, no-load current, and noise. The low-voltage winding is wound with high-quality copper foil, offering excellent insulation withstand capability and strong resistance to radial stress caused by short circuits.
