Designed with advanced manufacturing technology and rigorous quality control, this transformer delivers reliable power distribution solutions for various industrial and commercial facilities. It features a cast resin insulation structure that ensures excellent electrical performance and mechanical strength, making it ideal for environments with strict safety requirements. The SC(B)12 energy efficiency class 3 dry-type transformer is engineered to operate efficiently under high load conditions, providing stable power supply while minimizing energy waste. Its compact design and low noise operation make it a preferred choice for indoor installations where space and acoustic comfort are important considerations.
The SC(B)12 dry-type transformer is constructed with a reinforced mechanical structure that significantly enhances its short-circuit resistance capability. The high-strength cast resin coils and rigid clamping system can withstand the mechanical stresses caused by sudden short circuits, ensuring uninterrupted power supply and reducing the risk of equipment damage.
With a fully enclosed and sealed design, the GB20052-2020 compliant transformer eliminates the need for regular oil changes and leak inspections. The cast resin insulation is resistant to moisture, dust, and chemical corrosion, allowing it to operate reliably in harsh environments with minimal maintenance. This translates to lower operating costs and less downtime for your business.
As an energy efficiency class 3 dry-type transformer, the SC(B)12 model achieves excellent energy conversion efficiency, reducing power losses during transmission and distribution. This not only lowers your electricity bills but also contributes to environmental sustainability by reducing carbon emissions.
The advanced design of the low noise dry-type transformer results in a smaller footprint compared to traditional oil-immersed transformers, saving valuable installation space. Additionally, it incorporates noise reduction technologies that keep operating noise levels to a minimum, creating a more comfortable working environment for employees.

The fireproof dry-type transformer is widely used in locations where fire safety and environmental protection are critical. Its non-flammable and non-toxic properties make it suitable for:
Commercial buildings, shopping malls, and hotels
Hospitals, schools, and other public institutions
Industrial plants and manufacturing facilities
Data centers and communication base stations
Underground parking lots and tunnels
High-rise residential buildings
Dry-type transformers use cast resin as insulation and cooling medium, while oil-immersed transformers use mineral oil. Dry-type transformers are safer, fireproof, and require less maintenance, making them ideal for indoor and high-risk environments. Oil-immersed transformers are generally cheaper but require regular oil changes and have higher fire risks.
Yes, the SC(B)12 dry-type transformer is designed with moisture-resistant cast resin insulation, allowing it to operate reliably in environments with relative humidity up to 95% without condensation. For extremely humid conditions, optional anti-condensation heaters can be installed.
With proper installation and maintenance, the high load capacity transformer has an expected service life of more than 30 years. Its durable construction and high-quality materials ensure long-term reliable performance.
