Standard Input-Output Norms require imported transformer inputs to match manufacturing requirements; suspension of the SION is recorded. Standard Input-Output Norms prescribe specific inputs and allocated weights/volumes for outdoor Current Transformers above 36 KV up to and including 72.5 KV, listing components such as CRGO steel laminations, nickel-iron magnetic strips, copper winding materials, insulating paper, porcelain insulator, mild steel, and transformer oil. Determination of input proportions for manufacture must be followed, and applicants must ensure imported goods are those used or required in the export product. The SION is suspended per Public Notice No. 03/2024-25 dated 03-05-2024.
