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.
This type of high-voltage vacuum load switch and combined electrical appliance is suitable for three-phase AC 40.5kV, 50HZ power system, or with a set of distribution equipment and ring network switchgear, combined power station and other supporting use, widely used in wind power generation, network construction and transformation projects, industrial and mining enterprises, high-rise buildings and public facilities, can be used as a ring network power supply unit or terminal equipment. It plays the role of power distribution, control and protection. The technical performance of the product meets the requirements of GB16926-1997 and IEC420.This product has the advantages of large breaking capacity, safety and reliability, long electrical life, frequent operation, compact structure, small size, light weight, and basically no maintenance. It has the ability to break the rated current, overload current, short circuit current and prevent the equipment from running without phase, the switch has an obvious isolation fracture, and is equipped with a ground switch and an electric spring mechanism related to the closing capacity, and has the remote control ability.
Note: There are manual operating spring mechanism and electrical operating spring mechanism.| Model | Type | Rated voltage | Rated current | Rated frequency | Poles | Customizable |
| FN21-40.5 | High-voltage load switch | 40500V | 630A | 50HZ | 3 | Acceptable |
1. Switching load current and switching short-circuit current: used to switch load current, closed-loop current, no-load transformer and cable charging current, switching short-circuit current;
2. Can withstand short-circuit current: load switch equipped with ground switch, can withstand short-circuit current;
3. The arc extinguishing tube of the arc extinguishing device is composed of: the main shaft drives the piston to compress air when the brake is opened, so that the compressed air is expelled from the nozzle at high speed and the arc is blown out. In the closing state can pass the normal working current and the specified short circuit circuit;
4. Trip device with high breaking capacity fuse: by the phase tripping function, can cut off the short circuit current for protection equipment.
2. Ambient temperature: -25ºC~+40ºC;
3. Relative humidity: the daily average is not more than 95%, the monthly average is not more than 90%;
4. No conductive dust, corrosive gases and water vapor;
5. No fire and explosive risk;
6. The earthquake magnitude is no more than grade 8;
7. Pollution grade: II.
