Company Profile
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.
Product Description
As a clean way of energy production, photovoltaic power generation has developed rapidly at home and abroad, ZGS11-Z.G photovoltaic power generation modular substation is our self-developed series of product that meets the growing photovoltaic power generation power supply requirements based on the domestic and foreign advanced technology combined with the domestic demand.
Transformer, load switch, high-voltage fuse are installed in the transformer box, the use of transformer insulation liquid as the insulation and heat dissipation medium of the entire product. It adopts the fully sealed structure, the shell using a split, shot blasting, pickling, phosphating, respectively, spraying primer, intermediate paint, paint to achieve the surface of the anticorrosive properties, resistance to thick, ultraviolet radiation are more than the strength of the ordinary spraying, has the advantages of small size, light weight, easy to install and so on.
