Product Application

Our products are widely applied across the entire power system chain, including power generation, transmission, transformation & distribution, and consumption. They also serve specific sectors and demanding scenarios such as the new energy field, rail transit, data centers and new infrastructure, as well as specialized and harsh environments like explosion-proof settings (e.g., petrochemical and coal mining industries), ships, and offshore platforms.

We Are Irreplaceable - Here's Why

Two decades of deep industry experience have given us a profound understanding of every detail and the grand scheme of transformers. We not only inherit time-tested reliable techniques, but also integrate cutting-edge online monitoring and intelligent protection technologies to give traditional power equipment a modern soul, safeguarding the past, present, and future of the power grid.

Fully Automated Powder Coating Technology
Advanced software
Wire Winding Manufacturing Technology
Insulation Technology And Treatment
Intelligence And Data Analysis
Corrosion Protection
Sheet Metal Technology

Our company utilizes fully automated powder coating technology, providing superior, durable, and environmentally friendly surface protection for transformer casings.

The coating is aesthetically pleasing, scratch-resistant, weather-resistant, and corrosion-resistant.

Through automated control, we ensure that the coating thickness is uniform and the adhesion is firm on every transformer casing. This technology greatly improves product consistency and reliability, ensuring long-term stable operation of transformers even in harsh industrial environments.

We hold over 100 state-recognized intellectual property assets and numerous software copyright registrations for our specialized systems. Our solutions are expertly tailored to meet the specific demands of power grids in different countries, ensuring perfect adaptation to local conditions and a superior user experience. Advanced software, such as our ERP (Enterprise Resource Planning) systems, provides the critical technological support that underpins our clients' smooth and efficient operations.

The winding process is one of our core manufacturing technologies. Through precise wire diameter control, compact coil arrangement, and rigorous insulation treatment, we ensure that every coil product achieves exceptional consistency, stability, and energy efficiency, laying a solid foundation for the superior performance of power equipment.

Our company is equipped with advanced AC/DC insulation withstand voltage testers and high-precision insulation resistance meters, which form a solid foundation of our insulation technology capabilities. Based on these devices, we are able to perform comprehensive and rigorous insulation performance evaluations, providing crucial technical support for the long-term safe and stable operation of customer assets.

Our online monitoring products are "intelligent sentinels" and "diagnostic experts" stationed at industrial sites. They perceive risks 24/7, accurately perceive risks, empower users to shift from "passive response" to "active prediction", safeguard operational security in all aspects, and optimize asset performance.

Our power equipment cabinets have passed the authoritative CX standard corrosion test, with their corrosion resistance performance certified by professionals. Building on this foundation, key products further employ a specialized oxidation treatment process, forming a dense protective layer on the cabinet surface. This significantly enhances the anti-oxidation and corrosion resistance capabilities in harsh environments, ensuring long-term stable operation of the equipment.

Strong Environmental Adaptability

Business Center

Our online monitoring system acts like a smart steward for your office building, silently protecting the power distribution system 24/7. It ensures smooth elevator operation and continuous air conditioning power, providing uninterrupted and reliable power for your business activities.
Green Community

Bringing professional-grade safety assurance to the community. Our equipment continuously monitors the transformers that supply power to the entire community, preventing overloads and malfunctions, and ensuring the electrical safety of every household.
The Heart Of Industry

The Heart of Industry: In harsh environments such as factories, mines, or substations, power stability is a lifeline. Our products are specifically designed for demanding industrial environments, providing the most robust protection for uninterrupted production and critical facilities.
