The Market for Water-Cooled Transformers

Currently, in the maritime propulsion system, water-cooled transformers are primarily sourced from foreign equipment suppliers, both domestically and internationally. Our company is the first domestic manufacturer to produce water-cooled transformers for marine applications and has accumulated numerous significant achievements in this field.

Development History of CEEG Marine Transformers

In 2006, we commenced trial production of marine transformers and entered the market.

In 2007, our marine and offshore platform transformers underwent product appraisal organized by the Jiangsu Provincial Economic and Trade Commission and the Zhenjiang Municipal Economic and Trade Commission. A panel of experts unanimously acknowledged that our products possessed exceptional characteristics, including strong overload capacity, low losses, low noise, compact size, lightweight, and easy installation. The main performance indicators had already reached the leading domestic level.

In 2008, we initiated research and development on 12-pulse and 24-pulse rectifier transformers and entered the market.

In 2009, we commenced research and development on marine water-cooled transformers and secured our first batch of orders for eight units of 1600kVA transformers in 2010.
