XJ Group Corporation is the leading and large-scale backbone enterprise in the power equipment industry. In 2011, XJ Group Corporation became an electric power equipment manufacturing enterprise wholly owned by The State Grid Corporation of China (SGCC). It has begun to make its way into a brand new era of development. For many years, XJ Group Corporation has successively undertaken and completed development and manufacturing for a series of major international scientific projects and the manufacturing of major domestic engineering equipment, filling in many domestic voids. The main equipment that has been developed and manufactured has enjoyed widespread use across China's major domestic projects, accelerating the speed of progress in the domestication of China's major equipment, and has made important contributions to the raising of overall operation levels in the electric power industry.
It is a professional enterprise and a leading manufacturer and exporter of electric power products, parking systems, gateand garage door system, elevator and escalators, energy meters (watt-hour meters and automatic meter-reading system), water meters and gas meters, etc with the
Reliable quality and competitive price. Our products have been exported to Norway, Sweden, South Africa, Poland, South Korea, Japan, Britain, France, Netherlands, Germany, Hungary, Turkey, Cyprus, Croatia, Spain, Finland, Italy, Israel, Lebanon, U. A. E, etc.
