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
FZN25, FZRN25 vacuum load switch and combination electrical appliances, suitable for three-phase AC 50Hz ring network or terminal power supply and industrial electrical equipment, for load control and short circuit protection, load switch switching load, closed loop current, no-load transformer and cable charging current. The combination can break any current up to the rated short-circuit current. Direct acting isolation fracture and vacuum arc chamber linkage. It has manual and electric functions.
FZN25, FZRN25 unique transmission structure design, arc extinguishing chamber only in the closing and breaking of the moment to withstand high pressure, so small volume, light weight.
FZN25, FZRN25 can realize the isolation fracture and arc extinguishing chamber fracture one-time operation.
FNZ25, FZRN25 in the static contact and moving contact guide torch between the grounding switch and the grounding valve, both to ensure safety and convenient maintenance.
