As a professional manufacturer and exporter of distribution and power transformers, I recently attended the 4th EESA Energy Storage Exhibition one of the most influential and professional energy storage industry events in Asia Pacific. Held at the National Exhibition and Convention Center (Shanghai), this exhibition gathered more than 600 leading enterprises from the global energy storage chain, attracted over 60,000 professional visitors from more than 30 countries and regions, and became a key platform for showcasing cutting edge technologies, industrial cooperation and international trade.
Industry Influence of EESA 2025
The 4th EESA Exhibition has become a wind vane of the global energy storage industry. It covered the entire industrial chain including energy storage systems, PCS, BMS, EMS, core components and integrated solutions. High-level forums and technical seminars focused on global energy transition, large-scale energy storage construction, safety standards and overseas market expansion.
This event strongly boosted the connection between Chinese equipment manufacturers and the global market. A large number of international buyers from Europe, Southeast Asia, the Middle East and North America showed strong interest in Chinese-made transformers and energy storage supporting equipment, marking a new stage of China’s energy storage equipment going global.
Application Trends of Dry-Type and Oil-Immersed Transformers
During the exhibition, I focused on the application and technological trends of dry-type transformers and oil-immersed transformers in energy storage, grid connection and new energy supporting scenarios, and conducted in-depth exchanges with industry peers, technical experts and overseas customers.
- Dry-Type Transformers
Preferred for indoor, urban, commercial & industrial, data center and distributed energy storage due to high safety, flame retardancy, low noise and easy maintenance.
Clear trend toward higher energy efficiency, compact structure, intelligent monitoring and environmental protection.
Strong demand in gridconnected energy storage, microgrid and peak shaving systems.
- Oil-Immersed Transformers
Still the first choice for large-scale energy storage power stations, wind and solar farm integration, outdoor substations and high-capacity power distribution.
Advantages: strong load capacity, high reliability and cost-effectiveness for long-term operation.
Development trends: environmentally friendly insulating fluids, low loss, enhanced shortcircuit resistance and digitalized on-line monitoring.
Both types are core equipment for energy storage systems. The exhibition confirmed that stable, efficient and safe transformers are essential for largescale energy storage projects.
