Release Time:2025-06-18 17:49:22

Under the "Dual Carbon" goals, the global energy structure is undergoing accelerated transformation, and the power equipment industry is witnessing a new wave of technological upgrades. As the global leader in 3D wound core transformer technology, Haihong Electric, with its continuous innovation capabilities and market expansion strength, is emerging as a new quality productive force driving the development of the global energy-saving transformer industry.

Haihong's Digital and Green Technologies

Recently, Haihong Electric was invited to deliver a keynote speech at the EPOWER 2025 The 25th Shanghai international New Electric Power Equipment Exhibition, sharing its cutting-edge technological achievements in the energy-saving transformer sector with global industry experts.

Haihong Electric’s digital technology applications span the entire process of product manufacturing and operation. Its self-developed digital systems, such as the fully intelligent control manufacturing system for 3D wound core transformers and the Haihong Intelligent Energy-Saving Monitoring System, significantly enhance efficiency and quality through intelligent collaboration and digital management.

Smart products, including the Intelligent 3D wound core Oil-Immersed Transformer, Integrated Primary and Secondary 3D wound core Oil-Immersed Transformer, Intelligent 3D wound core Dry-Type Transformer, and Photovoltaic Intelligent Double-Layer Dry-Type Transformer Substation, are built based by the 3D wound core technology and incorporate intelligent monitoring capabilities. These products meet the development needs of smart grids for "observability, measurability, and controllability," providing safe, highly reliable, efficient, intelligent, and green terminal equipment for smart grid construction.

World-Leading 3D wound core Technology

Haihong Electric’s independently developed 3D wound core transformer technology revolutionizes the traditional planar laminated structure with a three-dimensional design, achieving breakthroughs in energy efficiency, noise reduction, and short-circuit resistance. Several innovative 3D wound core transformer models have not only filled international gaps in energy-saving transformer technology but have also been widely applied in major national projects such as the Beijing Winter Olympics, Hong Kong-Zhuhai-Macao Bridge, Daya Bay Nuclear Power Station, and Baotang Grid-Side Independent Battery Energy Storage Station.

Expanding Global Collaboration Network

Haihong Electric’s influence in the global market continues to grow. In recent years, an increasing number of international clients have visited Haihong’s production facilities to witness its robust R&D capabilities in 3D wound core technology. The company has actively expanded its overseas presence, promoting the global application of its technology through licensing agreements and engineering project collaborations. To date, Haihong has established technical partnerships in over 60 countries and regions worldwide, contributing its internationally leading energy-saving technology to the Belt and Road Initiative.

Facing the opportunities of global energy transition, Haihong Electric will further deepen the application of 3D wound core technology in the renewable energy sector. Backed by over 400 domestic and international patents, the company will solidify its technological leadership. Haihong’s future lies not only in providing high-efficiency, energy-saving transformers but also in advancing the industry toward green and low-carbon development, showcasing China’s manufacturing prowess in energy-saving transformers to the world.
