In order to meet the needs of high-quality economic development

China’s power grid is transforming from high-speed development to high-quality development

which puts forward higher requirements for the quality of high-voltage electrical equipment that forms the basis of the power grid. The vast majority of high-voltage electrical equipment have passed the type test verification

but in the actual operation of the power grid

one of the reasons for the operation accident is that the supplied products are inconsistent with the key parts of the type test object and the performance and quality of the replaced key parts do not meet the requirements. Product certification is an internationally accepted means of quality control

which is used to provide third-party certification for the quality of supplied products to meet the requirements of standards or specifications

but it has not been widely used in the field of high-voltage electrical equipment. From the perspective of product certification

this paper analyzes and discusses how to introduce product certification technology into high-voltage electrical equipment manufacturing industry

and uses the analytic hierarchy process（AHP） to evaluate and compare the factors affecting the quality

so as to provide relatively objective and reasonable certification results.
