The SGB series non-encapsulated H-class dry-type transformers utilize specialized manufacturing technology from MORA (Germany), ensuring that the products meet fireproof, waterproof, and environmental protection requirements. They are ideal for distribution systems and are widely used in subways, ships, mines, chemical plants, power enterprises, and densely populated buildings where safety and fire protection are critical.

Performance Features:

1. Excellent heat dissipation, long thermal lifespan, and extremely strong overload capacity; can operate at 120% overload under IP45 conditions without forced air cooling for extended periods.
2. Extremely high safety and flame-retardant properties; does not produce smoke under long-duration burning at 800°C.
3. Exceptional resistance to thermal shock (can be fully loaded immediately at -50°C).
4. 100% waterproof sealing, with excellent hydrophobic and moisture-resistant properties.
5. Unique coil structure and strong field calculations result in virtually no partial discharge.
6. Low losses with significant energy-saving effects; compared to the SC9 series dry-type transformers, no-load losses are reduced by an average of 10%, and load losses are reduced by 5%.
7. After the end of the service life, insulation materials and copper wires can be easily separated for recycling, causing no environmental pollution.
