The Development of Insulation Materials in Harbin Electric Machinery Company Limited

摘要

This paper introduces the progress of insulation technology for Harbin Electric Machinery Company Limited (HEC) from four aspects including the stator coil insulation system, anticorona technology, rotor insulation technology and supplementary insulation system. Rich-resin mica tapes molded insulation system is the key technology of HEC. The stator coils made by rich-resin molded technics reaches the advanced level in the world, "once mold cure technic of the corona and insulation materials" is another HEC key technology. The anti-corona technology of more than 20 kV generators, which is always improved and innovated by learning from foreign advanced experience, has been the special anti-corona technology system for HEC. HEC have study a series of new products by using these two key technologies. The generator rotor insulation technology and supplementary insulation materials are developed and innovated all the time with researching new products and improving insulation materials.
