Against the backdrop of accelerating the comprehensive green transformation of economic and social development, the low-carbon retrofitting and construction of thermal power plants has become an industry trend. Leveraging its self-developed Fully Insulated Low-Temperature-Rise 3D Wound Core energy-saving technology, patented cooling system technology, and live-line fan replacement technology, Haihong Electric has provided safe and highly reliable low-carbon power distribution solutions for multiple thermal power plants, assisting them in achieving low-carbon transformation and ensuring safe, continuous operation.

With urban development, power upgrades in old urban areas face numerous challenges: difficult site selection, long construction cycles, unstable power distribution quality, and resident concerns about equipment safety and noise. The Miniaturized Double-layer Prefabricated Substation launched by Haihong Electric, with its outstanding advantages of small footprint, high safety, and reliability, is becoming a "powerful assistant" in the power equipment renovation of old urban areas, providing efficient and convenient solutions for the transformation and upgrading of urban power distribution equipment.

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.
