The project involved a TR2 transformer (rated capacity: 2,500 kVA) at the production facility of a leading optoelectronics manufacturer in Chongqing, China. This transformer is dedicated to supplying power to the facility's sensitive and critical process equipment, primarily MOCVD (Metal-Organic Chemical Vapor Deposition) machines and other core production tools. The stable operation of these high-precision tools is directly linked to the plant's production yield, uptime, and product quality.
