CEEG's cast resin dry-type transformers, also called cast coil or encapsulated transformers, offer a maintenance-free, safe, and highly reliable power solution for demanding commercial and industrial applications worldwide. Our superior coil encapsulation technology, using high-quality epoxy resin, ensures exceptional performance in terms of short-circuit withstand, moisture resistance, and fire safety.

Backed by over 20 years of partnership with DuPont, CEEG VPI transformers combine industry-leading reliability with Class C (220°C) insulation. Designed for safety, resilience, and environmental protection, they offer high efficiency, superior overload, fully recyclable and zero harmful emissions, and NEMA 3R enclosure.

The CEEG 10kV oil-filled distribution transformer is meticulously handled at each stage to achieve low loss, low noise, low temperature rise, low partial discharge, high reliability, as well as no core hoisting and oil leakage. Products conform to a wide range of standards, including the United States, the European Union, Canada, the Middle East, Australia, and other markets for transformers

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.
