Dry-Type Transformer

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 SCZ18-10000/35 high voltage large capacity dry-type transformer is designed for long-distance power transmission demanding large capacity power and strong environmental resilience, especially the rise of clean energy has led to an increase in ultra-high voltage (UHV) transmission in recent years.

Designed for Marine Protection: Salt spray, mold, moisture, dust, and shock resistance. 
Product Diversity: Includes single-phase, three-phase, combination three-phase transformers, and offshore platform transformers.
Available in Both Epoxy Casting and VPI processes
DuPont Nomex® Insulation System: Excellent fire resistance and high insulation class.
Full Marine Classification Certification: Certified by leading classification societies, including CCS, ABS, BV, DNVGL, LR, KR, RINA, NK, and others.

1. Reduce no-load losses by 60% To 80% compared to the silicon steel transformer
2. Improved energy efficiency, energy conservation, and seismic resistance certifications
3. Green manufacturing with a shorter production process
4. Ideal for enhancing power system efficiency and promoting sustainability

CEEG produces rectification equipment that converts AC power from the grid into industrial-grade DC power, widely used in industrial production, transportation, and electrochemistry. In recent years, with the explosive growth of the hydrogen energy industry, CEEG dry type rectifier transformers have seen increasingly extensive application in water electrolysis for hydrogen production.

The variable frequency transformer rectifier is specifically designed to provide multiphase rectified power for medium and high-voltage frequency converters. Supported by DuPont Nomex® insulation, the rectifier is suitable for a wide range of medium to high voltage inverters, effectively filtering harmonics, protecting motors, dissipating heat, and preventing flames.
