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.
ZW20KF-12 Outdoor high voltage intelligent demarcation vacuum circuit breaker rated voltage 12kV, three-phase AC 50Hz outdoor high voltage switchgear. It is mainly used to break and close the load current, overload current and short circuit current of the power system. It is suitable for protection and control of substations, industrial and mining enterprises and urban and rural distribution networks, especially for places and cities with frequent operations
Network automation distribution network.
This product is compatible with the controller, which can meet the requirements of the distribution automation system, and can reliably and effectively complete the traditional recloser function. It adopts mature box-type sealing structure, filled with SF6 gas, has good sealing performance, so that it is not affected by the external environment, is a maintenance-free product. Its spring operating mechanism adopts direct chain main transmission and multistage trip system, which has high operation reliability and is a good product of column circuit breaker.
