SGB Series H-Class Low-Noise High-Overload Environmentally Friendly Non-Encapsulated Dry-Type Transformer

² Voltage level: 10~35/0.4kV.

² Capacity: 30~3150kVA.

² Safety Protection Features:
Adopts an H-class insulation system combined with NOMEX® paper as the core material, boasting a long-term temperature resistance of 180°C and complying with the UL94V-0 flame-retardant standard, fundamentally eliminating fire hazards. The non-encapsulated open structure and oil-free design completely eradicate explosion risks, meeting the safety requirements of crowded and high-risk scenarios.

² High Efficiency and Energy-Saving Features:

Utilizes high-permeability silicon steel sheets and optimized electromagnetic circuit design, reducing power loss by 10%-20% compared to ordinary models. Both no-load loss and load loss reach industry-leading levels. With 120% long-term and 150% short-term overload capacity, it maintains efficient operation even under load fluctuations, minimizing energy waste.

² Low Noise and Quiet Operation Features:

Achieves operating noise below 42dB (far lower than the industry average) through optimized core lamination technology and winding structure layout. The design avoids mechanical vibration amplification and is paired with a quiet heat dissipation structure, making it directly applicable to noise-sensitive environments such as data centers and medical facilities.

² Environmental Adaptability Features:

The optimized thermal management system enables stable operation in tropical climates with humidity exceeding 95%. Corrosion-resistant components and sealing design enhance durability in harsh environments. Environmentally friendly materials are used throughout the entire process, with VOC emissions nearly zero, complying with green standards such as the EU RoHS and adapting to scenarios with strict environmental requirements.

² Easy Maintenance Features:

The non-encapsulated open structure combined with VPI (Vacuum Pressure Impregnation) technology allows daily inspection and maintenance without complex disassembly. The modular design simplifies component replacement, reduces downtime for maintenance, and lowers long-term operation and maintenance costs as well as labor input.

² Structural Reliability Features:

Features interleaved laminated high-voltage pancake windings and low-voltage foil conductors with uniform current density distribution, ensuring low leakage reactance and enhanced short-circuit withstand capacity. The precision-balanced electromagnetic structure paired with high-strength fixing components can resist mechanical stress during transportation and operation, extending the equipment's service life.

² Application Adaptability Features:

Compact in size and flexible in installation, it is suitable for diverse scenarios such as high-rise buildings, chemical parks, and urban power grid upgrades. It not only meets the high-quality power supply needs of precision equipment but also maintains continuous operation of the power system under complex working conditions, offering strong versatility.

Applicable to industrial production, high-rise buildings, transportation hubs, data centers, new energy projects and urban power distribution networks. Suitable for factories, hospitals, subways, communication base stations and other venues requiring stable power supply and environmental adaptability.
