The quality supervision and inspection center of the National High and Low Voltage Electrical Appliance in Gansu Provincial Electricity Department

Test station in construction and the 110kV GISsubstation

Totally RMB1.5 billion was invested to the project covering an area of 300 mu. First phase will be the capacity for insulation type test (rated voltage of tested samples considered as 1200kV) of AC 1000kV and below grade electrical products (high voltage circuit breaker,isolating switch, current transformer, voltage transformer, lightning arrester and high voltage bushing, insulator, coupling capacitor, etc.); wire and cable type test ofAC 500kV and below grade and preliminary identification test; type test of power transformer withcapacity of 330kV/180MVA and 220kV/240 MVA and below grade; insulatorscontamination test of voltage 500kv and below grade; calibration and EMC test detection ability of voltage transformer 750kV and below grade.
