The "Administrative Measures for Installation (Repair, Test) Power Facilities Permits" will come into effect on October 11, 2020. The "Administrative Measures for Installation (Repair, Test) Power Facilities License" (State Electricity Regulatory Commission Order No. 28) promulgated by the former State Electricity Regulatory Commission on December 18, 2009 shall be repealed simultaneously. Huatian Power briefly introduces the new version of the guide for the selection of construction machinery and equipment required for the four-level power facility license for undertaking (repair, test) testing.
Obtain the four-level installation (repair, test) license, and can engage in the installation, maintenance or test activities of power facilities with voltage levels below 35 kV.
