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.
ZW12-12 type outdoor high-voltage vacuum circuit breaker is mainly used for 10KV overhead lines as outlet, segment and user boundary switch. The circuit breaker consists of two parts: switch body and intelligent control device. When the circuit breaker is used as a demarcation switch in the power supply line of the ring network, it should be equipped with double-sided PT (a removable switch body). The circuit breaker body can also be built-in special zero sequence current transformer, increase zero sequence grounding protection and alarm function, in the unidirectional injection power supply mode as a segment switch, branch switch or user boundary switch used, you can choose the built-in single PT or built-in single side double PT control device, can achieve automatic fault isolation and fault location function
