History
Innovation and breakthroughs, pioneering spirit and remarkable achievements
Faced with increasingly fierce market competition, the factory has established "technological innovation" as its core driving force. We have increased investment in R&D, assembled a professional technical team, and are committed to developing high-voltage, high-precision, miniaturized, and environmentally friendly products. We have successfully developed specialized instrument transformers and transformers suitable for smart grids and new energy (such as wind and solar) power generation, significantly improving the technological content and added value of our products. Our manufacturing process is moving towards automation and informatization, introducing advanced silicon steel sheet shearing lines, vacuum casting equipment, and fully automated testing lines to ensure product consistency and superior quality. Our market network has been further deepened, expanding from traditional power systems to multiple fields such as rail transit, industrial power, and data centers, establishing long-term and stable cooperative relationships with many well-known domestic enterprises.
Steady development, the brand is beginning to reveal its potential.
Steady development, the brand is beginning to reveal its potential. Entering the new century, China's power construction entered a period of rapid development. The factory seized the opportunity, expanded its production scale, and introduced advanced equipment, achieving an initial transformation from workshop-style production to modern manufacturing. The product line expanded from a single series of current and voltage transformers to a much richer range, and the factory began to venture into the field of power transformers, forming a complementary product structure. We highly value product quality and technological innovation. Many of our products have passed type tests by national authoritative testing institutions and obtained numerous product certifications. "Reliable and durable" has become the general market assessment of our "Four Mutual" products, and our brand influence is gradually spreading throughout the country.
Laying the foundation and starting a business, embarking on a new journey through hard work
In 1988, riding the wave of China's reform and opening up, the Sihui Instrument Transformer Factory was officially established in Guangdong. From the very beginning, we established power instrument transformers as our core product. In the rudimentary factory buildings, the first generation of Sihui instrument transformer workers, with their superb skills and hardworking spirit, hand-wound reliable instrument transformers, winning the trust of early customers and laying a solid foundation for the factory's survival and development. During this period, we initially established a quality management system, and our products successfully served power grid renovation and construction projects in Guangdong Province. The "Sihui" brand began to emerge in South China.
