The Group and Siemens have jointly established enterprise for the production of mutual inductors, electric reactors and pipe casing, and more specifically, 35-550kV oil-immersed mutual inductors, 72.5-800kV gas insulated switchgears(GIS), 72.5-1000kV capacitor voltage transformers, 10-69kV epoxy resin cast mutual inductors, hollow dry electric reactors, 17.5kV-550kV AC/DC epoxy resin oil-immersed capacitor casing pipes, and 40.5kV-1100kV oil-immersed capacitor casing pipes. Seven 1,000kV capacitor voltage transformers have been in operation at the Jindongnan-Jingmen ultra high-voltage trial demonstration project of State Grid Corporation of China. Meanwhile, LOPO low power mutual inductors have been successfully used in smart transformer station.
