At present, State Grid Eastward Electricity Transmission from Anhui, UHVAC project, double million on-load voltage regulation AC UHVAC transformer, undertaken by Baosteel and Baoding Tianwei Group, has successfully completed all the modelling test and routine test. All standards in technical agreement are followed, meeting all the needs from our clients, which is another breakthrough of Baosteel grain oriented silicon steel in the field of high end transformer. This time, State Grid has paid high attention to Baosteel's supply of GO silicon steel for double million project, and dispatched expert team to Baosteel several times to conduct the spot certification. In order to fulfill the supply task, Baosteel silicon steel team has actively visited the relevant clients, learn their request, promote material selection and supply strictly according to the procedure, and give full play to sequence synergy advantage during production process. In addition, consistency production key control point is continuously streamlined, adhering to PDCA+earnest, executing CP control plan so as to control the physical quality and properties.
It is reported that Eastward Transmission Project is the landmark program of UHVAC power transmission technology application in China. The boosting transformer of this line is the double million UHV transformer with highest voltage level and largest capacity in the world. The technology and manufacturing difficulties for Baoding Tianwei Group are huge. Therefore, the on-load AC transformer, as Baosteel is the material supplier, has been put into testing phase, and completed all type tests and relevant research experiments, with all the index superior to the requirement, earning the general consents from supervising experts of State Grid. Meanwhile, it symbolizes the high end process of Baosteel GO silicon steel has step onto a new stage.
