Scope

Main technical content: This standard specifies the seismic design requirements for AC electrical facilities with voltage levels of 1000 kV and below, and DC electrical facilities with voltage levels of ±1100 kV and below. It also stipulates the mechanical performance testing requirements for seismic isolation devices used in electrical facilities. This standard applies to the seismic design of electrical facilities in substations (converter stations) and the performance testing of seismic isolation devices used in electrical facilities. It is suitable for Class I to IV sites of substations with voltages of 750 kV and below, or converter stations with voltages of ±660 kV and below, in areas with seismic fortification intensities of 6 to 9 degrees; and for Class I to III sites of UHV substations and converter stations in areas with seismic fortification intensities of 6 to 8 degrees. The seismic design of electrical facilities in UHV stations in areas with seismic fortification intensities of 9 degrees and above or in Class IV site areas requires special research.
