The SF-M type 3000kVA 11.5kV three-phase oil-immersed distribution transformer is a high-efficiency power distribution solution that fully complies with IEC 60076 and national industrial standards. Adopting high-performance C.R.G.O. cold-rolled silicon steel core and high-purity oxygen-free copper windings, this transformer is configured with a standard 6.39% short-circuit impedance, realizing ultra-low no-load and load loss with greatly improved energy efficiency compared with traditional models. It adopts a fully sealed corrugated tank structure without conservator, which effectively isolates air and moisture, prevents insulating oil oxidation and deterioration, and significantly reduces daily maintenance workload while extending overall service life. The optimized mitered core structure ensures low-noise stable operation, with strong environmental adaptability. It is widely applicable for heavy-load industrial power supply, municipal grid reconstruction and large-scale commercial power distribution projects, serving as a reliable core power distribution equipment for 11.5kV power grid systems.
