Key Features

The fully prefabricated cabin assembly substation changes the traditional layout of electrical systems, civil engineering design, and construction methods for substations. The construction of substations is carried out in two main phases: factory production of prefabricated components and on-site installation. Standardized design, modular combination, industrialized production, and intensive construction make substation construction more environmentally friendly and refined.

1. In civil engineering: It improves the traditional layout of electrical systems, adheres to the principles of building energy conservation, material conservation, water conservation, and land conservation. The goal is to make the building structure lightweight, using on-site rapid assembly processes to shorten the construction period.

2. In electrical aspects: It requires the development of six major standard systems, including general substation design, component processing detailed drawings, factory production processes, on-site assembly processes, construction cost quotas, and assembly construction control.

3. The construction mode of fully prefabricated assembly substations requires the support of modern prefabricated parts and steel components. It redefines the traditional mode, and the prefabricated cabin has become an important part of power development.

Additional Information

Foundation Construction

The combined transformer should be installed on a horizontal concrete platform that can withstand its weight. Since most of the weight of the combined transformer is concentrated in the rear of the box containing the transformer body, and the front cabinet is mostly empty, the weight is relatively light. Therefore, the rear part of the platform should be strong enough to bear the weight of the combined transformer. At the same time, the front and rear platforms should be flat (generally, if it is difficult to achieve flatness, the foundation of the front cabinet can be slightly lower than the foundation of the rear transformer body, and concrete can be used to close it after positioning). This ensures the stable installation of the combined transformer.
