10kV Class S22 (Level 1 Energy Efficiency) Series Dual Winding Non-excitation Voltage Regulating Fully Sealed Transformer

The core of this product is made of high-permeability grain-oriented cold-rolled silicon steel sheets with a 45° fully mitered joint design, featuring low no-load current and low losses. The windings are made of high-strength paper-insulated or enameled copper wire, with a layer or disc structure, offering strong short-circuit resistance. With a capacity range of 30–63,000kVA, it is suitable for a wide range of applications.
