On December 1, 2017, the National Energy Administration made corresponding adjustments to the power test-qualified equipment. The test-qualified equipment in each province is the same, and at the same time, it saves some power companies in practice.

Equipment that is not commonly used in international work. Obtain a five-level installation (repair, test) license, and be able to engage in installation, maintenance or test activities of power facilities with voltage levels below 35 kV. Need to understand

You can click "Declaration Specification" to browse the application materials and filling specifications for the license for installation, repair, and testing of electric power facilities.
