Design Considerations For Seismic Performance Of Fuses In High-risk Areas In Power Systems

For buildings and infrastructure located in strong earthquake zones, relevant standards (such as IBC or OSHPD) require electrical equipment to maintain its structural integrity and functional status under seismic loads. Testing procedures cover stringent conditions such as multiaxial vibration and sustained loading to verify the dynamic response of components under high-intensity seismic loads.

Against this backdrop, the drop out fuse seismic resistance grade for use in earthquake zones must reach level 8 or above, with an emphasis on product design and engineering specifications. Determining the seismic resistance rating classification typically requires assessment based on seismic intensity or the seismic zone where the equipment is located, and professional evaluation is used to determine the fuse design and installation method.
