>> Product Introduction
The 35kV three-phase oil-immersed distribution transformer is a high-efficiency power solution compliant with ANSI C57.12.00, IEC 60076, and GB standards. Featuring advanced C.R.G.O. silicon steel cores and oxygen-free copper windings, it delivers ultra-low losses (S11-M series achieves 30% reduction vs. S9-M). The sealed tank design with corrugated/expansion radiators eliminates oil oxidation, extending service life while reducing maintenance.
Ideal for utility and industrial applications, its mitered core structure ensures quiet operation (<65dB) and enhanced safety. The conservator-free construction minimizes footprint while preventing moisture ingress. With models ranging from S9-M to S11-M, it provides flexible options for 10kV-35kV distribution networks nationwide.
