30-2500kVA 3D Wound Core Oil-Immersed Distribution Transformer
This series is widely used in 10kV and 6kV power transmission and distribution systems. The cores are entirely constructed using either three-dimensional or planar (user-selectable) laminated core structures. Compared to corresponding national standard products, no-load losses are reduced by an average of 30%, no-load current is decreased by 60–80%, and noise levels are lowered by 30–40%, delivering significant energy-saving benefits. Featuring a fully sealed corrugated oil tank structure, these transformers offer low losses and noise, an aesthetically pleasing design, excellent performance, maintenance-free operation, and extended service life. They represent a new generation of high-tech, high-performance, eco-friendly, and energy-efficient products within their category.
