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.
ZW43-12Y(G)/630-20 outdoor high voltage permanent magnet vacuum circuit breaker (hereinafter referred to as permanent magnet switch) is a three-phase AC 50Hz, rated voltage 12kV outdoor high voltage switchgear. The permanent magnet switch is mainly used as the 10KV outlet switch in the substation and the line protection of the load current of the sub-station, the overload current and the short current in the three-phase AC power system of 10KV switch.
Permanent magnet switch is composed of vacuum switch body, single stable permanent magnet operating mechanism and intelligent controller, so it has a wide range of cooperation and flexible and convenient action program setting mode, with high reliability and safety, is a new type of "electromechanical integration" intelligent high voltage switchgear with control and protection functions.
The circuit breaker complies with GB1984-2003, DL/T402-2007, DL/T403-2000 and other technical standards.
