Project Description
The new “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Order No. 28) promulgated by the former State Electricity Regulatory Commission on December 18, 2009 shall be repealed at the same time. Litai Power briefly introduces the new version of the guide for the selection of construction machinery and equipment required for the first-level power facility license for installation (repair, test) testing.
This table describes laboratory standards such as high-voltage generating equipment, electrical measuring instruments, oil and gas testing instruments, and commonly used instrument tables.
