The "small houses" used for power distribution that we see in industrial areas and residential areas are quality prefabricated substations, and a more vivid name can be called box-type substations. What you see may only be one kind. In fact, quality prefabricated substations are mainly divided into the following types:
1. European prefabricated substation
From the perspective of use, this may be the most widely used type of quality prefabricated substation. Their modular design makes it very convenient to manufacture and install. The equipment is completely pre-customized in the factory, and the appearance styles are more diverse, which can meet all the needs of customers to a great extent. European prefabricated substations are commonly used in 10kv~20kv power supply and distribution. European-style box-type substations generally consist of high-voltage switchgear, power transformers, and low-voltage switchgear.
2. American prefabricated substation
This is also a kind of box-type substation, which was introduced into China successively from the European-style box-type substation. The shape of the American-style box-type substation is different from that of the European-style box-type substation. Combined substation equipment. Therefore, they have another name called combined box change. In our country, the use of American-style box-type transformers is relatively much less.

3 buried substation
That is, a quality prefabricated substation buried underground. According to the needs, it can be divided into semi-submerged and fully submerged. The former is generally used for power supply in municipal construction and landscape gardens. Therefore, it is also called a landscape box change. The latter is to bury all the pre-installed box substations in underground built containers, and use them after waterproofing and anti-corrosion treatment.
4. Miniaturized box transformer
This is actually based on the specific products in the alternative box change design. It belongs to the range of European-style box change, but it is quite special. They occupy less land, have different internal structures, have a more personalized appearance, and have a higher degree of intelligent control. They are one of the representative products of modern and future quality prefabricated substations.
