    Box-type Substation

    Model: ZMXB2 Miniaturized intelligent prefabricated substation

    Application:

    With the development of modern urban power grid and the strategic goal of State Grid Corporation of China to build a world-class energy Internet enterprise. With the continuous increase of urban electricity consumption and the shortage of land resources, the demand for miniaturization of distribution stations (rooms) and distribution equipment is becoming more and more urgent. In the revision of the typical design of distribution network of State Grid Corporation of China, the miniaturization switch station type has been added, and after optimization, the area of each switch station can be reduced by more than 60% on average. The ZMXB2 series miniaturized intelligent prefabricated  substation developed by our company has the advantages of modular design, simple structure, minimum floor space, safety, reliability, no overhaul, less maintenance, high degree of automation and standardization, diversified appearance and coordination with the surrounding environment. It is suitable for crowded sections of modern cities and some relatively narrow spaces, and also meets the standard requirements of distribution automation of power grid companies.

    Features:

    This product is an alternative product of the United States, with small floor space, easy to make full use of the original environment and foundation for upgrading, short construction period and low investment. European-style box-type variable structure design, diversified appearance, can be designed to integrate with the surrounding environment. There is a communication room inside, which can realize remote control and data upload, and improve the efficiency of operation and maintenance. Compared with American box transformer, it has many functions, strong ring network ability and more stable and safer operation.

    ● Standardization: unified scheme, unified construction standards and modularization;

    ● Lean: totally sealed and insulated, popularize new technologies and processes, and improve the operation level of equipment;

    ● Shell mechanism: stainless steel or carbon steel is purchased, which has good corrosion resistance;

    ● Shell size: 2250*1300*2300 (width * depth * height unit mm).
