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.

Air-12 series of environment-friendly gas insulated metal enclosed switchgear is the use of vacuum arc extinguishing chamber arc extinguishing, environment-friendly gas as the main insulating medium, a small amount of solid insulation support, the main loop without any encapsulation, Distribution switchgear with zero gauge pressure or small positive pressure (air pressure of the air box ≤0.02MPa) in normal operation, and the insulation capacity of the relative ground and phase to meet the air insulation requirements at zero gauge pressure.
Environment-friendly gas insulated metal closed switchgear is the most commonly used three-phase AC intelligent environment-friendly gas insulated cabinet, and is widely used in a variety of complete sets of switchgear, with the concentration of the domestic population, the power market must be supported, environment-friendly gas insulated switchgear is also with the development of the market, the demand will be more and more large. At the same time, because the product brings together data collection and control, data processing and storage, switching equipment online monitoring and advanced analysis and other functions in one, online intelligent monitoring and management of the distribution network, so that the distribution network runs in the best state of safety, reliability, quality and efficiency, and realizes the remote monitoring, control and management of the power system distribution network. It realizes the needs of power grid optimization, power safety, power management, energy saving and consumption reduction. At the same time, the system can be widely used in transportation, factories, hospitals, schools, buildings, residential areas and commercial office buildings and other intelligent power distribution fields.
