Straight to CBTC | CEEG Joins DuPont China for a Stunning New Product Launch!

Shanghai is a city full of stories,

and full of infinite possibility.

Here, on the CBTC show floor,

CEEG showed its style and demonstrated its strength!

From July 26 to 28, the three-day CBTC 2023 China International Energy Storage and Lithium Battery Technology Exhibition opened at the National Exhibition and Convention Center in Shanghai. As a leading brand in power transmission and distribution, CEEG focused on cutting-edge energy storage products and technologies and held the "Pooling Green Power, Creating a Shared 'Lithium' Future — 2023 New Product Launch for the Amorphous Alloy Dry-Type Transformer for Energy Storage", and the event drew a lively, standing-room crowd!

1 Joining Forces, Opening the Future

At 2:00 p.m. on July 26, the 2023 new product launch for the amorphous alloy dry-type transformer for energy storage officially began. Zhang Xinrong, Deputy General Manager of CEEG; Mr. Liu Haifan, China Sales Manager for the Nomex® electrical insulation business at DuPont Water & Protection; Lian Junshan, Deputy Secretary of the CPC Committee at CEEG; together with industry media, partners and guests on site, witnessed the product's global debut. The event was hosted by Qian Xuelian, head of CEEG's Marketing Center.

Mr. Liu Haifan addressed the audience on behalf of DuPont. He noted that energy storage and lithium batteries are an important part of China's 14th Five-Year Plan for new infrastructure, and a vital component of DuPont's global market strategy. CEEG is a key strategic partner of DuPont, and the two companies have worked together since 1999 on transformers insulated with "paper".

Combining the high-temperature resistance, high mechanical strength, high electrical insulation and high stability of Nomex® aramid insulation with CEEG's refined craftsmanship yields transformers that are safer, more energy-efficient and more environmentally friendly. As the energy storage and lithium battery industries continue to grow, more and more amorphous alloy storage transformers will find their way into every sector, and DuPont looks forward to advancing hand in hand with CEEG toward the frontiers of the new energy storage industry.

Zhang Xinrong, Deputy General Manager of CEEG, delivered a speech. He noted that CEEG and DuPont have maintained a stable strategic partnership over many years, working closely to develop new products and open up the future. Their jointly developed products span a number of specialized industry fields and continue to lead the industry's innovation frontier.

The new-generation amorphous alloy dry-type transformer for energy storage launched today with DuPont opens a new chapter in the two companies' cooperation in energy storage. It is poised to become a "golden pairing" in the new energy storage supply chain and a new milestone in CEEG-DuPont collaboration. Going forward, CEEG will stay true to its mission of "delivering quality power to the world" and contribute its strength to China's role in the global green energy transition!

Before the media and audience on site, the two sides jointly unveiled the new product — the amorphous alloy dry-type transformer for energy storage. The launch marks another major breakthrough in CEEG's R&D, underscoring the company's technical strengths and strategic vision in the new energy sector and supporting the industry's vigorous growth.

2 Innovative Breakthroughs, Striving for Excellence

At the launch event, Chen Bangxiu, Senior Engineer at CEEG, gave a technical walkthrough detailing the new product's development process, technical highlights and applied innovations.

Product Highlights

1. The amorphous alloy dry-type transformer for energy storage uses DuPont™ Nomex® aramid insulation, offering high-temperature resistance, high mechanical strength, high electrical insulation and high stability;

2. Vibration model simulation analysis is applied to effectively reduce noise;

3. A proprietary semi-encapsulated structure provides strong dust protection, high insulation performance and strong overload capability;

4. The low-voltage winding uses foil-wound construction with Nomex® material for interlayer and end insulation. Lead busbars and copper are welded with argon-arc welding on dedicated equipment, and after overall drying the winding is cured through VPI vacuum pressure impregnation and high-temperature baking, significantly reducing load noise in operation;

5. The high-voltage winding uses segmented cylindrical layered coils with air-duct cooling, sealed end faces and an outer Nomex® paper wrap — dustproof, moisture-proof and salt-spray resistant;

6. The active part takes the windings as its load-bearing core with a suspended core structure, and the core's overlap joints use a special glue end-sealing process to keep stress on the core to a minimum while keeping weight light;

7. Flame-retardant, explosion-proof and non-polluting, with a high fire-safety rating — outstanding characteristics well suited to solar-storage-charging stations, data centers, hospitals, smart campuses and similar settings.
