A prefabricated cabin-type substation is a type of substation with a steel structure as its main body, representing an integrated substation form. Its main features include factory-based production and on-site assembly, which can significantly reduce construction time and labor costs. Additionally, due to its modular design, it allows for easy expansion and maintenance.

A typical prefabricated cabin-type substation is composed of infrastructure, incoming and outgoing line devices, transformers, power distribution devices, control systems, and air conditioning equipment. The infrastructure mainly supports the weight of the substation. The incoming and outgoing line devices connect to high-voltage cables, the transformer converts voltage, the power distribution device distributes the electrical energy output by the transformer, the control system monitors and controls the electrical facilities, and the air conditioning equipment regulates indoor temperature and humidity.

The manufacturing process of a prefabricated cabin-type substation is generally divided into four stages: design, manufacturing, transportation, and installation. In the design stage, the substation is designed according to the customer’s requirements. The manufacturing stage takes place in modern factories, utilizing fully automated production lines to save labor costs and improve production efficiency. In the transportation stage, the substation is divided into several standard modules, which can be transported to the destination via different methods such as road, rail, or air. In the installation stage, professional installation teams assemble the substation on-site, completing it quickly.

The primary advantages of prefabricated cabin-type substations are speed, convenience, and safety. Since most of the manufacturing is completed in the factory using fully automated production lines, the on-site assembly takes only a few days before the substation is ready for use. In contrast, traditional above-ground substations require on-site construction of steel structures and infrastructure, resulting in longer construction times and higher labor costs. Additionally, prefabricated cabin-type substations save time and cost during transportation and installation. The modular design also makes this type of substation suitable for various environments and locations, meeting the needs of different customers.

In summary, prefabricated cabin-type substations use factory-based production and on-site assembly, offering the advantages of shorter construction times, reduced labor costs, and easier expansion and maintenance. As green energy development rapidly advances, prefabricated cabin-type substations will become an essential part of future power system construction.
