Main testing equipment configuration for third level repair, installation, and testing qualifications
brief introduction
On December 1, 2017, the National Energy Administration made corresponding adjustments to the qualification equipment for power testing. The qualification equipment for testing in each province and region is the same, and some equipment that is not commonly used by power enterprises in actual work is omitted. A brief introduction to the new version of the construction equipment selection guide for the third level power facility license for installation (repair, testing) testing is provided.
Obtaining a third level installation (repair, testing) license, one can engage in the installation, maintenance, or testing activities of power facilities with voltage levels below 110 kV.
To learn about the application materials and filling specifications for the installation, maintenance, and testing of power facility licenses, you can click on "Application Specifications" to browse.
