Power Cable Laboratory

Power Cable Laboratory is located in Wuhan Campus of China Electric Power Research Institute. Founded in 2000 and approved as one of the first "Laboratories of State Grid Corporation of China" in 2007, the Laboratory is in the charge of State Grid Corporation of China and is operated and managed by High Voltage Department under China Electric Power Research Institute.

It specializes in the research on safe operation performance standard, engineering design specifications, test methods, and operation and online monitoring technology of power cable line equipment.  The major research directions of the Laboratory include power cable operation reliability and charged detection technology (online monitoring), cable current carrying capacity optimization technology, power cable aging mechanism and state evaluation technology, high-voltage cable line field test and defect location technology, DC crosslinking cable technology, and basic UHV AC cable technology, etc. Furthermore, the Laboratory also engages in formulation and revision of technical standards for the whole process of operation and research on relevant technical instruments, ranging from supervision on power cable manufacturing, inspection of incoming goods, cable pavement and accessory installation, final acceptance inspection and test, cable line operation management, and state maintenance, etc.

The Laboratory is equipped with UHP cable test hall, outdoor preliminary identification test field, 800kV/30A and 800kV/6A non-PD power frequency series resonance systems, 1600kV/40mA and 800kV/30mA DC power systems, 3000kV/600kJ and 3600kV/720 kJ impulse voltage systems and relevant non-electrical performance test equipment. It can carry out type test and preliminary identification test on 500 kV (and below) DC and AC land cable and submarine cable systems. Owning FTIR spectrometer, differential scanning calorimeter, broadband dielectric and impedance spectrometer, crosslinking DC cable space charge testing system, cable conductor AC resistance test system and other apparatus and equipment, it can also conduct experimental research on basic properties of cable and cable materials.
