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.
ZW51-12 type outdoor AC high-voltage vacuum circuit breaker shape structure is mainly composed of pillar members, operating mechanism, isolation switch, current transformer, etc., of which the isolation switch and current transformer can be selected according to user needs.
The product adopts full sealing structure, integral forming sleeve, outdoor core type current transformer and miniaturized spring operating mechanism (permanent magnet operating mechanism) with advanced and reasonable design, compact structure, reliable performance, no condensation, no rust and so on.
The product can be configured with an intelligent control unit (FTU) upgrade to an intelligent integrated switch to fully meet the needs of distribution automation.
