The necessity of securing seismic performance of non-structural structures and of seismic design for electrical equipment installed in buildings is emphasized. The electrical cabinet refers to a power system that receives power from the power plant and distributes the amount of power required by the receiver at each place of use. The pendulum-type seismic isolator allows the upper load to be supported on the pendulum-type table fixed to the frame with very high rigidity. This can obtain the seismic isolation effect that fundamentally blocks the horizontal displacement caused by the earthquake from being transmitted to the superstructure. In this paper, the concept and basic configuration of a pendulum type seismic isolator will be reviewed.
