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.
FZW28-12F series outdoor demarcation vacuum load switch is suitable for outdoor three-phase AC power distribution system with rated voltage of 12kV and rated frequency of 50Hz as open and close load current and short circuit current.
It is suitable for substations, industrial and mining enterprises, cities and rural power grids as protection cities, automated distribution networks of rural power grids and places of frequent operation;
The boundary load switch is composed of FZW28-12 vacuum load switch and controller, which are electrically connected through aviation socket and outdoor sealed control cable. It can reliably judge the zero sequence current and interphase break current inside and outside the detection boundary, and can be suitable for distribution systems with different neutral ground modes.
