S20/S22 Series Dry Type Three-Phase Transformer: Pioneering Energy Efficiency and Environmental Stewardship

Transformer is a device that uses the principle of electromagnetic induction to change AC voltage. Its main components are primary coil, secondary coil and iron core (magnetic core). Its main functions include voltage conversion, current conversion, impedance conversion, isolation, voltage stabilization (magnetic saturation transformer), etc. Classification by insulation and cooling method. Transformers can be divided into oil-immersed, dry-type and gas-insulated types according to insulation and cooling methods. Among them, oil-immersed transformers include oil-immersed self-cooling type, oil-immersed air-cooling type, oil-immersed water-cooling type and forced oil circulation cooling type. Oil-immersed Power Transformers have been widely used because of their advantages of good heat dissipation, low loss, large capacity and low price. The S20 and S22 series of eco-friendly oil-immersed transformers are designed to meet the growing demands for energy efficiency and environmental sustainability in power distribution systems. Each series builds on the previous one, offering progressively better energy efficiency and sustainability features, making them ideal for modern power infrastructure.
