On September 29, the world’s first 110kV energy-saving amorphous alloy 3D wound core oil-immersed power transformer was officially connected to the grid and put into operation at the Hongchang Substation of Shantou Power Supply Bureau, Guangdong, under China Southern Power Grid. The successful deployment of this critical equipment injects strong momentum into the power grid’s advancement of green power system construction and the implementation of the national “Dual Carbon” strategy, while also marking China’s entry into the global forefront of green power equipment technology.

Driven by the "Dual Carbon" goals, Haihong Electric has consistently fulfilled its "green development" mission through technological innovation, actively responding to the national call for energy conservation and carbon reduction. The company has deeply participated in government-led energy efficiency diagnostic initiatives for manufacturing transformer equipment. By leveraging its energy-saving 3D Wound Core technology, Haihong Electric addresses critical power consumption challenges, injecting robust momentum into industrial green transformation.

In an era of frequent extreme weather events, natural disasters like typhoons and torrential rains pose severe challenges to the reliability of power distribution systems. Relying on its highly reliable prefabricated substation technology, excellent insulation protection capabilities, and rapid-response after-sales services, Haihong Electric has repeatedly demonstrated its "steadfast and unshakable" quality during major disasters, proving to be a solid backbone for grid security.

When the transformer in the substation fails to meet energy efficiency requirements, or experiences issues such as overheating, excessive losses, or insufficient load capacity, must the entire substation be replaced? Not necessarily! From the perspective of user economic benefits and resource utilization, Haihong Electric offers a low-carbon, environmentally friendly solution—the Low Temperature Rise substations Upgrade Solution. This approach avoids wasteful extensive dismantling and replacement, focusing instead on precise upgrades. It effectively addresses problems like high losses and high temperature rise in substations, enhancing both performance and safety reliability, thereby revitalizing the original substation with new energy.

To promote the high-quality development of heavy-duty truck electrification, we must address the multiple severe challenges faced by charging and swapping stations: megawatt-level power impacts, continuous high-temperature environments, prolonged ultra-high load operations, dust erosion, and more. Practical engineering experience shows that Haihong Electric's Miniaturized Double-Layer Double-Transformer Substation provides a perfect solution.

The Implementation Plan for Large-Scale Equipment Renewal in Key Energy Sectors, jointly issued by the General Office of the National Development and Reform Commission and the Comprehensive Department of the National Energy Administration, identifies hydropower stations as one of seven key renovation areas. It advocates "prudently advancing the renewal and retrofitting of hydropower equipment." Addressing transformer upgrades for hydropower plants, HAIHONG Electric Co., Ltd. introduces the 110kV 3D Wound Core Power Transformer, providing a green, safe, and highly reliable equipment renewal solution. This technology has received national recognition and is listed in China's Catalog of Energy-Saving Technologies and Practices Proposed for International 'Top Ten' Contests under industrial energy-saving technologies.
