Henan Energy Electric Equipment Co., Ltd. was established in 2011 and is an excellent and reliable power equipment manufacturer in China. The company mainly develops and produces oil-immersed transformers, dry-type transformers, box-type substations, high-voltage switches, and medium and low voltage complete sets of equipment. The equipment put into production and operation of the project advocates energy saving, intelligence, informatization, 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.
ZW27A-12 outdoor column oil-free high voltage vacuum circuit breaker synthesizes the advantages of current domestic column vacuum circuit breaker, absorbs the mature experience of Japan Toshiba's VSP5 column automatic sectioner, and is ahead of similar domestic products in performance. It better meets the needs of the electricity department, and is the leading vacuum circuit breaker in the field of products in our country. The circuit breaker is suitable for the three-phase power system of 12kV and below AC 50Hz, which is used for dividing and combining load current, overload current and breaking short circuit current.
