Audited Supplier Audited by an independent third-party inspection agency
Since 1999, China Electric Equipment (Jiangsu) Transformer Manufacture Co., Ltd. (CEEG) has proudly partnered with DuPont, pioneering the use of DuPont Nomex paper as insulation material in China. As trailblazers, CEEG was the first to incorporate this advanced insulation in their open-ventilated dry-type transformers, setting a benchmark in the industry.
Our VPI Transformer is meticulously engineered to excel in environments demanding impeccable fireproofing and resilience against harsh conditions such as extreme rating waves, dirt, and moisture. Ideal locations include airports, subways, power plants, mines, hospitals, skyscrapers, shopping centers, densely populated areas, oil industries, and nuclear power plants, ensuring safety and reliability where it's needed most.
Product Features
The CEEG Vacuum Pressure Impregnated Transformer stands as a paragon of durability and efficiency, offering an exceptional array of features: robust overload capacity, superior high-temperature resistance, unparalleled safety and reliability, fire retardancy, moisture resistance, eco-friendliness, low noise levels, ease of maintenance, minimal partial discharge, and a crack-resistant design.
1. DuPont Nomex® Paper
Since establishing a strategic partnership with DuPont in 1999, CEEG has been at the forefront, utilizing DuPont Nomex® Paper in manufacturing non-encapsulated dry-type transformers. This high-grade insulation material ensures a class H or C insulation standard, with tightly wrapped windings that withstand short-circuit impacts even after prolonged service, ensuring long-lasting performance and reliability.
2. Silicon Steel Core or Amorphous Alloy Core
Our cores, crafted in a three-phase structure, utilize premium cold-rolled grain-oriented silicon steel sheets, jointed at a precise 45-degree angle with 7-step seams, or superior amorphous alloy strips. Insulated tape separates core from windings, while specialized square tubes and draw plates secure the structure. Moisture and rust-resistant resin coats the surface, sharply reducing no-load loss, no-load current, and noise. Notably, the amorphous alloy core model slashes no-load loss by 60%, dramatically boosting energy efficiency.
3. HV & LV Coils
Our high-voltage winding features a continuous structure for enhanced mechanical strength and efficient heat dissipation. Its damp-proof design withstands heat shock with partial discharge under 5PC, recoverable after service life. The F-grade DMD lamination low voltage foil is pre-soaked in epoxy resin for impeccable layer insulation, processed via VPI equipment and a high-temperature curing machine, ensuring a void-free finish. High current taps on low voltage windings cater to demanding applications.
4. Additional Features
Our transformers offer versatile primary and secondary voltages to align with diverse customer specifications.
Equipped with fans to enhance emergency overload capacity, ensuring optimal performance under duress.
Boasting self-extinguishing capabilities, our transformers offer superior fire resistance compared to oil-based alternatives.
Expertly suited for managing harmonic loading, our transformer ensures stability and efficiency in complex applications.
Integrated core loop testing functionality specifically tailored for turbo generator sets.
Our transformers feature low energy content in case of fire, reduced weight, and excellent heat wave resistance, ensuring both safety and efficiency.
Certification
CEEG's dry-type transformers are certified with KEMA E2, C2, and F1 ratings for environmental, climatic, and fire behavior. We proudly stand among the earliest Chinese manufacturers to surpass the rigorous KEMA test, underscoring our commitment to excellence.
Strategic Cooperation with Dupont Since 1999
