Key Technical Features

• Advanced Low-Loss Core Design:Constructed with high-grade, low-loss amorphous alloy or high-permeability silicon steel core, which dramatically reduces no-load (core) losses, the primary source of energy waste in transformers.

• Optimized Energy Efficiency:Meets or exceeds stringent energy efficiency standards (such as IE3, IE4 or Chinese GB Standard). Its design minimizes total ownership cost by prioritizing high performance at both full and partial loads.

• Robust Oil-Immersed Construction:The time-tested oil-immersed design provides excellent insulation and heat dissipation, ensuring stable operation, a long service life, and reliable performance under fluctuating load conditions.

• Reduced Operating Costs:The significant reduction in energy losses translates directly into lower electricity bills, offering a rapid return on investment and a smaller carbon footprint.

• Durable and Reliable Performance:Features a fully sealed tank to prevent oil oxidation, corrugated radiators for effective cooling, and high-quality components to ensure minimal maintenance and maximum uptime.

Performance Parameters: Technical Parameters of S11-30~1600/6~10/0.4 Series Oil-immersed Distribution Transformer
