Product Presentation


With the development of the industrial revolution, human science and technology has been greatly improved but also brings serious environmental pollution and resource shortage caused by the massive consumption of fossil fuels, so that human beings have to find new energy to replace traditional fossil fuels.


With the continuous progress of science and technology, new energy power generation has covered wind, photovoltaic and marine energy, etc., which has promoted the rapid formation of the related supporting industry chain. Based on the design and manufacturing of the original combined transformer and pre-installed substation, Combined with the requirements of wind turbines, solar photovoltaic inverters and their related transmission networks for booster equipment, the special substation for new energy power generation has been widely used in major power generation companies and various environmental conditions.


This series of products implement the national standard GB1094 《Power transformer》, GB/T6451 《Three-phase oil-immersed power transformer technical parameters and requirements》 and GB20052 《Power transformer energy efficiency limit value and energy efficiency grade》.


ZGS11-Z.G series; Photovoltaic power generation is a special combined substation for photovoltaic field, which is a special equipment that increases the voltage of 0.27kV-0.315KV at the export of the inverter to 38.5kV and connects the output to the grid. Our products combined the needs of domestic photovoltaic power generation with the current situation tailored for photovoltaic power generation of new products, which is reliability, safety, economy, small footprint, small investment, easy installation and maintenance, good looking and other characteristics. This product adapts to the trend of establishing photovoltaic power generation on a large scale in the country, and is the ideal supporting product of photovoltaic power generation system.


Structural Features


● The product is specially designed according to photovoltaic technology and has the characteristics of meeting the special requirements of photovoltaic ring network.


● Divided cabin structure, high voltage cabin, low voltage cabin and transformer cabin constitute a separate unit. The high-voltage outlet unit and low-voltage inlet unit are separated from the transformer, which is more safe and reliable, and the layout structure can be divided into mesh type, font type, L-shape and other shapes.


● The radiating fin is directly exposed to the air and has strong heat dissipation ability, which can prevent the failure of the electrical components due to the overheating of the temperature in the cabin.


● Strong overload capacity, low loss, strong short-circuit resistance and lightning protection ability, superior performance.


● The cabin is made of new materials, with anti-theft function, and can resistant to seawater, salt spray corrosion after anti-corrosion spray treatment.


● Small size, simple structure, reasonable layout, convenient transportation and installation.


● Good looking , and can be well coordinated with the surrounding environment.


● High degree of automation and agility in communicating.
