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.
Product Description
FN12-12D and FN12-12DR are three-phase high-voltage switchgear with rated voltage of 12KV and rated frequency of 50Hz. They are used to divide load current, closed-loop current, no-load transformer and cable charging current, and close short circuit current. They can break short circuit current and install load switch of ground switch. Can withstand short circuit current, mainly used in three-phase ring network or terminal power supply urban distribution power station and industrial electrical equipment, for load control and short circuit protection.
