After several decades of reform and opening, the development of China's electric power has made great progress, the manufacturing industries have gradually entered a world-class level, and many well-known international companies have chosen to set up factories in China.
At the same time, we realized that many developing countries' power infrastructures are still very poor,so our mission is to provide the most cost effectiveproducts to world, and these products are transformed to meet relevant international
standards (IEC and IEEE) based on widely used and proven reliable products in China in recent thirty years.

Eventually, we could help the developing regions to update their energy quality and improve people’s life.
