The current seismic requirement level of electrical equipment in China is lower than other international standards, such as IEEE 693, IEC 62271 and JEAG 5003. And the seismic level of electrical equipment is decided by combining several conditions of fortification intensity, site condition, and classification of design earthquake in China, which is not easy to determine the seismic level of electrical equipment quickly and conveniently. According to the characteristics of substation electrical equipment for high gravity center, large quality, soft structure and brittle material, and comparing domestic and foreign related codes about seismic fortification level of electrical equipment, the advantages of grading fortification were summarized, which would be more conducive to the work of production, call, qualification, and design for the electrical equipment. So grading fortification for electrical equipment in China was proposed. In order to obtain the grading fortification principle, the seismic reliability of electrical equipment was determined to calculate. Design earthquake accelerations of exceeding probability of 2% in 50 years which were higher than the norm value and obtained by survey were used as calculation parameters, two typical pillar electrical equipment were chosen as calculation modals, seismic reliability of electrical equipment in ordinary porcelain and high-strength porcelain was calculated using the FOSM method. The use of design earthquake accelerations of exceeding probability of 2% in 50 years will meet the seismic target of no collapsing with strong earthquake that will further assure seismic safety of electrical equipment. The seismic reliability of high-strength porcelain equipment was obviously higher than the value of ordinary porcelain equipment. So it is an effective method to improve equipment seismic capacity through replacing ordinary porcelain by high-strength porcelain. And the reliability results were as indexes to determine the low, medium and high levels. 0.1g and below was as low assessment level, peak acceleration was taken 0.1g. 0.1g~0.4g was as medium assessment level, peak acceleration was taken 0.4g. Above 0.4g was as high assessment level, peak acceleration was taken 0.6g.Comparing the peak acceleration with IEEE and IEC, it is found that the proposed seismic fortification for electrical equipment is more reasonable in whole district compared with IEEE and IEC, the acceleration value of each seismic level is moderate which is slightly lower than the value of IEEE and IEC. According to the grading level of seismic fortification, using ArcGIS technology, the distribution was mapped, and the applications of the series map will provide the dicision-making basis for reasonable planning electrical equipment.
