Abstract：As one of the important basic facility in substation, the seismic performance of substation insulators directly affects the seismic reliability of substation system. Using quasi-static loading test, the aseismic performance of substation insulators is discussed from three aspects: height, axial pressure ratio and number of insulators assembled. Bearing capacity, deformation capacity, hysteresis curve, and energy dissipation capacity are analyzed based on the above parameters. The test results show that all insulator specimens undergo bending failure after quasi-static loading test. The bearing capacity and energy dissipation capacity of the specimens gradually deteriorate with the increase of the height of the specimens. As the number of insulators decreases, The peak bearing capacity and energy consuming capacity of each insulator decreases as the number of insulators increases. Finally, a refined finite element model is established based on experiments and its reliability is verified, which lays a foundation for subsequent seismic analysis of power system.
