Since 1999, China Electric Equipment (Jiangsu) Transformer Manufacture Co., Ltd. (CEEG) has proudly partnered with DuPont to revolutionize transformer technology in China. We are the trailblazers in utilizing DuPont Nomex paper as insulation in our pioneering open-ventilated dry-type transformers.
Our Vacuum Pressure Impregnated Transformer, with its robust three-phase design, is expertly engineered to thrive in environments demanding exceptional fireproofing, handling of substantial rating waves, and exposure to dirt and moisture. Ideal for use in airports, subways, power plants, mining, hospitals, skyscrapers, shopping centers, densely populated areas, oil industries, and nuclear power plants.
Product Features
The CEEG Vacuum Pressure Impregnated Transformer is a masterpiece of engineering, delivering superior overload capacity, exceptional temperature resilience, and unwavering safety and reliability. This fire-retardant, moisture-resistant marvel is eco-friendly, operates quietly, requires minimal maintenance, and exhibits low partial discharge while remaining crack-free.
1. DuPont Nomex® Paper
In our landmark partnership with DuPont since 1999, CEEG blazed a trail as the first Chinese company to adopt DuPont Nomex® Paper for insulation in non-encapsulated dry-type transformers. This innovation provides a high insulation class of H or C, ensuring that the wrapped windings maintain a robust structure capable of withstanding short-circuit impacts over years of reliable service.
2. Silicon Steel Core or Amorphous Alloy Core
The heart of our three-phase transformer is crafted from premium cold-rolled grain-oriented silicon steel sheets, meticulously lap-jointed at 45 degrees with seven stepping seams, or from cutting-edge amorphous alloy strips. Encased in insulated tape for full protection from windings, the core is fortified with moisture and rust-resistant resin. This sophisticated design significantly reduces no-load loss, no-load current, and noise. Specifically, our amorphous alloy core model achieves a remarkable 60% reduction in no-load loss, dramatically boosting energy efficiency.
3. HV & LV Coils
Our high-voltage winding, with its continuous structure, delivers outstanding mechanical strength and excellent radiation capability. It resists dampness, withstands heat shock, and maintains a partial discharge below 5PC. Impressively, the winding is fully recoverable after its service life. The F-grade DMD lamination low voltage foil undergoes a meticulous epoxy resin presoak for layer insulation, followed by an advanced VPI (vacuum pressure impregnation) process and high-temperature curing, ensuring flawless void-free insulation. High current taps are available for the low voltage winding.
4. Additional Features
Our transformers accommodate multiple voltages on both primary and secondary sides, tailored to meet diverse customer requirements.
Equipped with fans, our transformers can handle increased emergency overload capacity, ensuring enhanced operational safety.
Boasting a self-extinguishing feature, our transformers offer superior fire resistance compared to traditional oil-based systems.
Perfectly engineered to handle harmonic loading, enhancing performance in challenging environments.
Specially designed core loop testing transformer for turbo generator sets, ensuring peak operational efficiency.
Our transformers feature low energy content in the event of a fire, reduced weight, and outstanding resistance to heat waves, ensuring maximum safety and efficiency.
Certification
Holding prestigious KEMA E2, C2, and F1 certifications, our CEEG dry-type transformers are recognized for their superior Environmental, Climatic, and Fire Behaviour standards. We proudly stand as one of China's foremost manufacturers to pass the rigorous KEMA test.
Strategic Cooperation with DuPont Since 1999
