Medium Voltage Transformer

CEEG 30/33/34.5/35kV oil-immersed power transformers are designed for medium-voltage transmission and distribution networks, industrial, energy, public facilities, and other sectors. Built with a proven core-type structure and advanced manufacturing processes, these transformers deliver low loss, low noise, strong short-circuit withstand capability, and long service life, fully meeting international energy efficiency and reliability requirements. Additionally, CEEG provides flexible designs tailored to local grid standards, environmental conditions, and project-specific requirements.

CEEG 110/138kV oil-immersed transformers, also called liquid filled transformers, utilize a hybrid insulation structure, with DuPont Nomex insulation material (Class C heat resistance) used in the hot spot areas of the transformer. They use high-quality mineral oil or natural ester fluids. All indicators strictly comply with IEC standards, providing high overload capacity, safety, and reliability throughout their entire service life.

The CEEG mobile transformer is available in 10kV, 35kV, 110kV, and other options. The product meets the performance demands of vehicular transport on various road conditions and can operate for several months, or even one to two years.

The CEEG energy storage oil transformers, specifically designed for use in energy storage systems (ESS), offer enhanced short-circuit resistance, harmonic mitigation, temperature and cooling management, advanced insulation and material selection, compact and modular design, and corrosion and environmental resistance. These performances makes it suitable for integrating with renewable energy sources and battery storage systems.
