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.
FZW32-40.5 outdoor high voltage isolated vacuum load switch after strict type test and long-term trial operation assessment, all the technical performance indicators have reached GB3804 and IEC standards, suitable for rated voltage 24KV, rated current 630A, three-phase AC 50Hz power supply network.
Main Features:
1. Vacuum arc extinguishing, no explosion risk, no need to repair.
2. The isolation knife is connected with the three-phase vacuum interrupter, and there is an obvious isolation fracture when the brake is opened.
3. All parts of the body are made of stainless steel, and the bottom frame is made of stainless steel or hot dip galvanized carbon steel with ultraviolet protection coating to ensure the normal operation of the body in the outdoor environment.
4. The installation mode is mainly double-rod, electric operation, and can also be operated by electric or remote control.
5. Large breaking capacity, safe and reliable, long electrical life, frequent operation.
6. Widely used in rural power grid, urban network, railway and other power distribution line transformation.
