Under the national “dual-carbon” goals, the power grid sector faces growing demand for environmentally friendly and energy-efficient equipment. Traditional transformers suffer from high energy losses and pollution risks. In contrast, dry-type distribution transformers feature an oil-free design that eliminates the risk of soil and water contamination caused by insulating oil leakage. These transformers also utilize premium silicon steel sheets and advanced winding processes to minimize both no-load and load losses.
High-performance models like the SCB18 series enable significant reductions in overall power consumption. As new energy-efficiency standards continue to take effect, these next-generation transformers are rapidly replacing outdated equipment and becoming the preferred choice in power system modernization.
What Is a Dry-Type Distribution Transformer?
A dry-type transformer uses solid insulation materials—such as epoxy resin—to encapsulate its coils, while cooling is achieved through natural or forced air circulation. With no insulating oil required, these transformers completely avoid oil leakage and fire risks, providing a safe and eco-friendly power solution.
Energy-saving, low-noise dry-type transformers represent an evolution of standard dry transformers. They incorporate advanced materials like high-grade silicon steel or amorphous alloys along with optimized coil designs to deliver both improved efficiency and quieter operation.
Why Choose Energy-Saving, Low-Noise Dry-Type Transformers?
1. Exceptional Energy Efficiency
Energy-efficient dry-type transformers deliver outstanding performance through two key design optimizations:
Low No-Load Loss: Even when idle, transformer cores consume energy due to magnetization. Using amorphous alloy cores reduces these losses by 60–80% compared with traditional silicon steel cores.
Low Load Loss: Optimized coil design minimizes resistance during load operation, improving system efficiency.
Because transformers operate continuously throughout the year, the cumulative savings are significant. Selecting Level 1 or Level 2 energy-efficient transformers in compliance with China’s GB 20052 standard allows companies to lower energy bills and typically recover cost differences within just a few years—making these products a high-return, long-term investment.
2. Ultra-Low Noise Performance
In areas such as hospitals, schools, offices, or residential buildings, low noise levels are essential. Traditional transformers often generate disturbing hum caused by core magnetostriction—the vibration of silicon steel under magnetic influence.
Noise Reduction Technologies: Modern dry-type transformers use step-lap core structures, reduced flux density, high-pressure insulation, and vibration-damping components. These technologies bring noise levels down to below 50–55 dB, ensuring quiet operation that meets environmental standards and enhances comfort in sensitive locations.
3. Safety and Reliability
Safety is one of the greatest advantages of dry-type transformers:
Oil-Free Design: Completely removes fire and pollution hazards associated with oil leakage. The epoxy resin structure is flame-retardant and self-extinguishing.
Strong Insulation & Overload Resistance: Epoxy resin casting provides excellent protection against moisture, dust, and corrosion, while allowing superior overload capability and long service life.
Maintenance-Free Operation: Unlike oil-immersed transformers, these units require no oil inspections or replacements, significantly reducing maintenance costs.
4. Environmentally Friendly Solution
Energy-saving dry-type transformers contain no toxic substances such as PCBs and are manufactured from recyclable materials. Their low environmental footprint during production and operation aligns with green energy development initiatives and helps companies strengthen their sustainable brand image.
