Henan Energy Electric Equipment Co., Ltd. was established in 2011 and is an excellent and reliable transformer manufacturer in China. The company mainly develops and produces oil-immersed transformers, dry-type transformers, box-type substations and high and low voltage complete sets of equipment.The equipment put into production and operation of the project advocates energy saving, intelligence, information and mechanization. The company has established the Henan Triangle Energy-saving Transformer Engineering Technology Research Center,with 71 utility model patents and 15 invention patents.With years of accumulation in the transformer industry and strong technological innovation capabilities, HZEC Products are sold to the Middle East, North America, South America, Europe, Southeast Asia, Africa and other regions, covering more than 40 countries.
The 220kV transformer is a high-voltage oil-immersed transformer with a core-type structure. It can be classified by phase number into single-phase transformers and three-phase transformers; by voltage regulation method into on-load tap-changing transformers and no-load tap-changing transformers; by winding coupling method into power transformers and autotransformers; by the number of windings into double-winding, three-winding, and three-winding plus balance winding transformers. Additionally, it includes special types such as split transformers and combined transformers. The product is designed according to IEC international standards, IEEE standards, and current national standards.
Advanced electrical, magnetic, thermal and mechanical force calculation software is used to calculate the electromagnetic field and magnetic leakage distribution, carry out wave process analysis, and select a reliable insulation margin to ensure reliable product performance.
