Latest News

Accelerating the replacement of high-cost, high-energy, outdated production processes and production is the future development trend. If the company lacks the spirit of high-tech innovation, the long-term precision is positioned at the level of medium and low-end transformer products, and does not improve the energy-saving of transformers. Improve the structure and production process of the transformer, so that the energy consumption level of the transformer can be improved steadily, and it will lose its competitiveness and be slowly eliminated.
