The special pre-installed box-type substation for wind power generation is a complete set of substations that are manufactured and assembled in the factory in advance, including step-up transformers, high-voltage load switches, low-voltage switches and auxiliary equipment such as power transformers, arranged in a common shell and passed the type test. It is the same as the European box-type substation in structure and form, so it is also called “wind power European substation”. Its performance fully conforms to GBT17467-2010 “High Voltage/Low Voltage Pre-installed Substation”. It is a new type of step-up equipment launched for the special requirements of wind power generation. Because it has the advantages of strong complete set, easy installation, short construction period, low operating cost, high structural strength and strong anti-corrosion performance, it is fully suitable for beaches, grasslands, deserts and other operating environments with harsh natural conditions. The product has passed the type test of Wuhan High Voltage Research Institute, and its performance fully meets the requirements of wind farms.
