Lower Transformer Temperature Rise: We Have Always Focused on Fundamental Research

Against the backdrop of the global energy transition, improving transformer energy efficiency is key to energy conservation and emission reduction. In this field, Haihong Electric has always looked deep into the core—fundamental research on transformer temperature rise.

Recently, as the country’s call to strengthen fundamental research and achieve high-level scientific and technological self-reliance gains momentum, the entire team at Haihong Electric has been deeply inspired. As emphasized by Mr. Xi Jinping, fundamental research is the source of the entire scientific system. Haihong Electric firmly upholds this spirit, believing that corporate innovation is not an overnight achievement. Instead, it requires starting from fundamental research and going through a long period of exploration before translating into practical applications.

Take Haihong’s renowned 3D Wound Core Technology as an example. Both breakthroughs in full insulation technology and the conception of a unique cooling system originated more than two decades ago. To tackle the industry challenge of "reducing operating temperature rise," Haihong’s team started with the most basic physical principles—material properties, magnetic circuit structures, and product designs— equipment R&D, process improvement, and material adaptation. It is this determination to "sit on the cold bench" that makes Haihong understand: without 28 years of accumulation and breakthroughs in fundamental research, there would be no low-temperature-rise transformers today. Innovation demands relentless effort and uncompromising investment.

Responding to the call of the Party and the country, Haihong Electric has integrated foundational innovation into the company’s DNA. Currently, we strongly advocate for "micro-innovation" across all links—from product R&D, equipment design, testing, and production processes to after-sales service. Every employee is encouraged to propose new ideas. Whether optimizing a process or improving a tooling fixture, any attempt to enhance efficiency and reduce temperature rise is fully supported by the company. This culture of innovation with full employee participation has deepened Haihong’s technological moat.

Despite our profound expertise, we remain true to our original aspirations. Over 28 years of development, Haihong Electric has adhered to the business philosophy of "Genuineness, Honesty, and Sincerity". Amid intense market competition driven by low prices, we fearlessly explore uncharted technological territories. Haihong never takes shortcuts. We rely on real technical data, serve customers with sincerity, and manufacture products that users can trust. This steadfast brand identity is the secret behind the long-term stability and energy-efficient operation of Haihong’s products.

The path of fundamental research is long and challenging, but progress is achievable with persistence. Rooted in fundamental research and thriving on micro-innovation, Haihong Electric continues its journey toward green energy efficiency, delivering cooler, quieter, and more efficient "Chinese cores" to the global power system.
