Henan Energy Electric Equipment Co., Ltd. was established in 2011 and is an excellent and reliable transformer manufacturer in China. The company mainly develops and produces oil-immersed transformers, dry-type transformers, box-type substations and high and low voltage complete sets of equipment.The equipment put into production and operation of the project advocates energy saving, intelligence, information 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.
24/20kV distribution transformer refer to a static electrical appliance in a power distribution system that converts AC voltage and current according to the law of electromagnetic induction to transmit AC power. In some areas, power transformations with a voltage level below 20kV are called "distribution transformer" or "blending" for short. The installation of "matched" places and places is both a substation. Distribution transformers should be installed on the column or open floor installation.
