Transformer frame manufacturing specializes in the pre-assembly of transformers, supporting structures, connecting components, and protective devices within a factory, forming a standardized, rapidly installable complete frame system. The core business of these factories includes the design and welding of the frame steel structure, pre-installation of insulators and leads, prefabrication of the grounding system, and overall anti-corrosion treatment.
Unlike decentralized on-site processing, factory production utilizes specialized jigs, automated welding robots, and precision bending equipment to ensure that the dimensional tolerances of each frame component are controlled within millimeters, while significantly reducing the risks associated with working at heights on-site. During manufacturing, factories strictly adhere to national standards such as GB/T 10228 and DL/T 5352, conducting item-by-item testing of weld strength, anti-corrosion layer thickness, and electrical clearances, ultimately forming a closed-loop quality control system from material intake to finished product delivery. This specialized manufacturing model has become a key element in improving the overall efficiency and reliability of power infrastructure projects.
