Technical Data for 10 kV Class S22 Three-Phase Dual-Winding No-Excitation Voltage-Regulating Distribution Transformer (Level 1 Energy Efficiency)

This oil-immersed transformer meets the Level 2 energy efficiency requirement of the GB 20052-2020 energy efficiency standard. It is a product independently developed by our company, leveraging high-permeability, high-performance electrical steel sheet materials and newly researched and applied manufacturing processes. Through optimized and innovative design of the core and winding structures, it achieves reduced losses and noise, making it a truly proprietary development. With low losses and low noise—noise levels are on average 20% lower than those specified in the current national standard JB/T 10088-2016—the product performance has reached an advanced domestic level, delivering significant energy-saving benefits, improving power quality and supply reliability, and serving as an environmentally friendly, green, energy-efficient device. The winding ampere-turn distribution is well balanced, resulting in minimal leakage flux, high mechanical strength, and strong short-circuit withstand capability.
