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.
FZW-27.5/D1250-20 type outdoor high voltage AC vacuum load switch-isolation switch combination electrical appliance (hereinafter referred to as combination electrical appliance), single-phase column structure, novel structure, obvious visible fracture, the use of operating mechanism to drive the vacuum arc extinguishing chamber, with large breaking capacity, no arc when breaking and closing current, no fire and explosion risk, fast and frequent operation, Long electric life, maintenance-free and so on.
Combined electrical appliances are single-phase AC 50Hz, rated voltage 27.5kV single-pole outdoor high-voltage switchgear (altitude 2000 meters), widely used in electrified railway, used as load breaking current, no-load transformer, cable current, capacitor current and closing short-circuit fault current.

Altitude: ≤2000m;
The load isolation switch is installed on an outdoor column, and must be able to break and close the normal load current of the line, and can integrate the function of the isolation switch to form an obvious visible fracture. The negative tea isolating switch can be installed in the power supply place of the locomotive depot, subdivision kiosk, return section, station yard and other sections, instead of the isolating switch installed on the column, eliminating the circuit breaker dedicated to cutting off the normal load current.
