Since 1999, CEEG has cultivated a pioneering partnership with DuPont, proudly becoming the inaugural Chinese company to incorporate DuPont Nomex paper into the insulation of open-ventilated dry-type transformers. This alliance signifies a milestone in technological advancement and innovation.
This exceptional product is specifically engineered for environments demanding rigorous fireproof standards and performance amidst large power fluctuations and challenging conditions like dirt and moisture. Ideal applications include airports, subways, power plants, mining industries, hospitals, high-rise buildings, shopping centers, densely populated areas, oil sectors, and nuclear power facilities.
Product Features
The CEEG Vacuum Pressure Impregnated Transformer stands out with its robust overload capacity and superior high-temperature resistance. It is synonymous with safety, reliability, and fire retardance, offering moisture resistance and eco-friendly characteristics. Enjoy minimal noise, straightforward maintenance, low partial discharge, and a crack-free experience.
1. DuPont Nomex® Paper
Since establishing a strategic relationship with DuPont in 1999, CEEG has been at the forefront in utilizing DuPont Nomex® Paper for non-encapsulated dry-type transformers. This innovative insulation material endows transformers with a high-class insulation grade of H or C. The tightly wrapped windings exhibit remarkable durability, capable of withstanding short-circuit impacts even after extensive service use.
2. Silicon Steel Core or Amorphous Alloy Core
Our three-phase core is crafted from premium-grade cold-rolled grain-oriented silicon steel sheets, meticulously lap-jointed at 45 degrees with seven stepping seams, or high-quality amorphous alloy strips. Insulated tape wraps the core to prevent winding contact. A unique square tube and draw plates secure the structure, while moisture and rust-resistant resin protect the surface. This design significantly reduces no-load loss, no-load current, and noise. The amorphous alloy core model is particularly efficient, boasting a 60% reduction in no-load loss and substantial energy efficiency improvements.
3. HV & LV Coils
Our high-voltage winding features a continuous structure that ensures exceptional mechanical strength and thermal dissipation. It excels in damp-proofing and heat shock tolerance, with partial discharge below 5PC, and offers recyclability post-service life. The F-grade DMD lamination low voltage foil undergoes epoxy resin presoak for layer insulation, followed by VPI (vacuum pressure impregnating) and high-temperature curing to achieve void-free insulation. High-current taps for low voltage winding are also available.
4. Additional Features
Flexible primary and secondary voltage options to cater to customer specifications
Fan installation enhances emergency overload capacity
Self-extinguishing capabilities provide superior fire resistance compared to oil-based alternatives
Engineered to manage harmonic loading efficiently.
Core loop testing transformer uniquely designed for turbo generators.
Features low energy content during fires, reduced weight, and excellent heat wave durability
Certification
CEEG's dry-type transformers proudly possess KEMA E2, C2, and F1 certifications, highlighting their excellence in environmental, climatic, and fire behavior classes. As one of China's pioneering manufacturers to pass the KEMA test, we set a benchmark in quality and performance.
Strategic Cooperation with Dupont Since 1999
