Product description

Highlights at a glance

  • 100% electrolytic copper windings and low-loss grain-oriented silicon steel to slash electricity consumption, run cooler under peak demand, and deliver a CE & ISO-certified weatherproof design for decades of reliable outdoor operation. Built for next-generation grid infrastructure, this three-phase oil-immersed transformer cuts no-load and load losses by up to 30%, significantly lowering total cost of ownership (TCO) and O&M expenses. The hermetically sealed tank with IP54-rated corrosion resistance withstands extreme temperatures, UV exposure, and coastal humidity, making it ideal for substations, industrial parks, and renewable microgrids. Advanced natural/mineral oil thermal circulation ensures stable heat dissipation, while premium copper conductivity minimizes I²R losses and extends insulation life. Fully compliant with IEC 60076, DOE 2029, and EU Ecodesign efficiency standards, it supports optional IIoT DGA monitoring for predictive maintenance, seamless smart-grid integration, and circular oil reclamation. Compact, utility-grade, and future-proof engineered to keep your power network lean, green, and uninterrupted.
