XJ Power Co., Ltd is a subsidiary of XJ Group Corporation of State Grid Corporation of China. XJ Power Co., Ltd researched the high-frequency switching DC power supply system in 1996 and put it in mass sale in 1998, the next year the product passed through the joint checkup by National Electricity Corporation and National Machine-Building Industry Bureau. The company has offered thousands sets of the PZ61 series high-frequency switching type DC supply system equipment to various substations and power plants ranged from 10KV to 500KV and even to 600MW generating units domestic and abroad for six years. The products supplied gained common praise from the users and clients for their stable and reliable running, excellent state of arts, good appearance and high intelligence.

In December 1999, the first DC supply system composed of nine 30A/220V high-frequency switching rectifier modules put into commercial running in a power plant in the country. This set is manufactured and supplied by the XJ Power Co., Ltd.  It has running normally and smoothly for more than four years long and performed very well. The rectifier modules of 30A/220V and 50A/110V type hold the largest capacity and the running time are longest in the country.

The accommodation provides uninterruptible DC power for the equipment of protection, control and drive, etc. in electrical power plants (single generating unit capacity≤1000MW)，hydro-power stations and various substations(35KV~750KV).
